The so-called civil field refers to several fields such as electric power, construction, medicine, and petrochemical. Internationally, thermal cameras are widely used in these fields. However, the application of infrared thermal cameras in these civil fields in my country is still in its infancy, and the entire development space is still relatively large. Next, let us understand the application of thermal cameras in the civilian field. Here are some answers.
Here is the content list:
Applications in the power industry.
Applications in the construction industry.
Applications in the medical industry.
Applications in the petrochemical industry.
Although the power industry is currently the industry with the most civil infrared thermal cameras in my country, as the most mature and effective means of online power detection, thermal cameras can greatly improve the operational reliability of power supply equipment. Therefore, with the continuous development of my country's economy, the power industry in other provinces will also use thermal cameras more.
According to the investigation of the application of thermal cameras in the construction industry by relevant departments, although there are many construction enterprises in my country, they have not yet reached the level of having a thermal camera in everyone. If every construction enterprise is equipped with a thermal camera, it will not only promote the market demand for thermal cameras but also greatly improve the work efficiency of construction enterprises and reduce costs.
The human body is a natural source of infrared radiation. When the human body develops a disease, the heat balance of the human body will be destroyed, so the measurement of the temperature change of the human body is an important indicator for the diagnosis of diseases in clinical medicine. The thermal camera can accurately display and record the temperature distribution of the human body for further pathological analysis. Today, medical thermal cameras have become an effective tool for diagnosing superficial tumors, vascular diseases, and skin conditions. In medical research, the application of thermal cameras in medicine has become a special research topic.
We know that much important equipment in petrochemical production works under high temperature and high-pressure conditions, and certain dangers are lurking, so online monitoring of the production process is very important. The use of thermal cameras can detect information related to product conveying and piping, refractory and thermal insulation materials, ruptures, thinnings, blockages, and leaks in various reactors. In this way, the two-dimensional temperature distribution on the surface of equipment and materials can be obtained quickly and accurately, thereby ensuring the safety of use.

The thermal camera will be subject to certain wear and tear during use, and these problems will cause the performance of the thermal camera to decrease. Therefore, the daily maintenance of the thermal camera is necessary. It not only reduces the generation of dirt and wear but also effectively increases the service life of the thermal camera. Next, let us learn more about the maintenance methods and precautions of thermal cameras. Here are some answers.
Here is the content list:
Maintenance method.
Maintenance Precautions.
To avoid damage to the thermal camera, first use compressed air to remove large particles of dust attached to the inside and outside of the thermal camera, and then wipe it off with a clean, soft cloth. When cleaning the camera lens, gently wipe the lens with a soft cotton cloth dampened with a little non-corrosive solution or a mild diluted soap solution. When cleaning the thermal camera body, use a clean, slightly damp cotton cloth to gently wipe, if necessary, soak the cloth with a solution of water and a small amount of mild soap before wiping. When the use is completed, the thermal camera should be covered with the lens cover as soon as possible, and stored in the carrying case to avoid dust. After the thermal camera has been used for a certain number of years, it needs to be calibrated. Generally, it needs to be calibrated in about 2 years under normal use.
In the process of maintaining the thermal camera, pay attention to the following points. First, do not use too much force when wiping the thermal camera to avoid damage to the thermal camera. Second, when wiping the lens of the thermal camera, it is forbidden to completely immerse the cotton cloth in the liquid. The lens is the information transmission window, and the maintenance of the lens is very important. Third, when wiping the camera body, be careful not to use strong acid or strong alkaline detergent for cleaning. Also, remember not to place the thermal camera in a cool and humid place. Fourth, to avoid damage to the thermal camera, it is necessary to ensure that the working environment does not exceed the working tolerance limit of the thermal camera equipment.

The thermal camera has incomparable advantages and characteristics of other products of the same type. The infrared thermal camera has excellent performance and remarkable effect. However, thermal cameras also require scientific use. If it is not cared for and maintained during use, or it is often operated in an incorrect and non-standard way, it will also affect the accuracy and service life of the instrument, and cause the instrument to fail to varying degrees. Next, let's take a look at the common failure analysis of thermal cameras. Here are some answers.
Here is the content list:
Sometimes it works and sometimes stops, and the measurement process is unstable.
The monitor screen shakes and cannot be stabilized.
Image quality is unclear or misplaced.
This may be caused by improper wiring or poor contact with the thermal camera. With the increase of use time and frequency, foreign matter such as dust may be deposited on the line connection, and the metal may also undergo an oxidation reaction when exposed to the air for a long time. These will form obstacles to the line connection, resulting in short circuits and other conditions. If this happens to the thermal camera, it must not be taken lightly, because if it is handled improperly, it will not only seriously affect the performance of the device, but may even cause irreversible damage, causing losses and inconvenience to users.
This situation is mostly caused by the interference of the transmission signal of the thermal camera or the damage of the signal transmission of the transmission cable. With the rapid development of information technology, within the scope of people's living space, the unit density is almost filled with signals of different transmission frequency bands, which will inevitably interfere with each other and affect the stability and safety of the equipment. As the transmission cable is a very important key link in the whole system, the transmission reliability of different media and equipment is also different. If the on-site environment is harsh, it will be affected to different degrees. It is recommended to take corresponding measures to eliminate the interference of surrounding signals as much as possible during the operation of the thermal camera, and at the same time, select the configuration you want to adapt to according to the actual situation to avoid affecting the imaging quality.
The overall operation of the thermal camera involves the linkage of multiple links such as the host, monitor, and transmission equipment. If this happens, you need to check each link one by one to find the key to the problem. For example, check whether the parameter settings of the instrument are correct and standardized, whether the host is operating normally, whether the monitor has line connection problems, whether the transmission equipment is intact, and so on. If necessary, seek help from professional technicians.

The thermal camera can convert the temperature distribution image of the target object into a video image by detecting the infrared radiation of the object. With thermal cameras, we can see things that our eyes cannot, such as people hiding behind the grass. The research scope of infrared detection technology includes the transmission, reception, and subsequent information processing of infrared radiation. It has penetrated many fields of military and civilian use and has become one of the most important detection technologies today. Next, let's dive into some technical information about thermal cameras. Here are some answers.
Here is the content list:
The state of thermal imaging technology.
The development of detector technology.
The development of infrared thermal imaging technology has gone through three generations. The first-generation thermal cameras all work in long-wave infrared. The long-wave infrared radiation energy of the target at room temperature far exceeds the medium-wave infrared radiation, and there is an atmospheric transmission window at 8-14 μm. In this way, a small number of detection elements and optomechanical scanning technology can meet the application requirements of long-wave infrared imaging. One of the highlights of the second generation of infrared imaging technology is the emergence of area array infrared focal plane detector technology, which expands the working band of thermal imaging technology to medium-wave and short-wave infrared. The third-generation thermal imaging detection technology is developing in the direction of large area array, multi-color detector, and high sensitivity.
Uncooled infrared detectors are mainly developed in the direction of smaller pixel pitch, wafer-level packaging, and ASIC integration. Smaller pixel pitch means that larger area array detectors can be made on the same size chip. Wafer-level packaging can greatly improve economies of scale and production efficiency, thereby reducing production costs. The use of chip integration instead of PCB circuit board-level component integration significantly reduces the size of the imaging module and also reduces the cost of mass production. Infrared detectors are a key component of thermal imaging in thermal cameras. It can be divided into refrigerated and non-refrigerated types. Cooled infrared detectors have many advantages, such as faster response speed, higher sensitivity, longer detection distance, and more stable performance. However, the performance advantage can only be realized in a low-temperature environment. This makes the cooling infrared detectors have a high cost, large volume, and weight, and are mainly used in military and scientific research fields. At present, its development direction is mainly in improving the working temperature, reducing the dark current, miniaturization, multi-wavelength detection, and system integration. Uncooled infrared detectors are small in size, low in cost, and have a long service life, but their accuracy is relatively poor. They are widely used in military and civilian fields that do not require high imaging performance.

A monocular thermal camera is to transform the invisible infrared energy emitted by the object into a visible thermal image, and the different colors on the thermal image represent the different temperatures of the object being measured. So how should we choose a monocular thermal imaging camera? Here I will briefly introduce the relevant content.
Here is the content:
Pixel aspect.
Temperature aspect.
Resolution of the monocular thermal camera.
The first step is to determine the pixel level of the monocular thermal camera to buy. Most monocular thermal cameras are related to the pixel level. Relatively high-end products in the civilian monocular thermal imaging camera pixel 640*480=307,200, this high-end monocular thermal imaging camera to capture the infrared picture clear and delicate, measured at 12 meters the minimum size is 0.5*0.5cm; mid-range monocular thermal imaging camera pixel 320*240=76,800, measured at 12 meters the minimum size is 1*1cm; low-end monocular thermal imaging camera The minimum size of the target is 2*2cm at 12 m. The higher the pixels, the smaller the size of the target.
The temperature range of the object to be measured is determined according to the temperature range to choose the appropriate temperature band of a monocular thermal camera. Most of the monocular cameras on the market today are divided into several temperature classes, not the larger the temperature class span the better, the temperature class span of small temperature measurement will be relatively more accurate. In addition, the general monocular thermal camera needs to measure objects above 500 ℃, it is necessary to equip the corresponding high-temperature lens. The temperature resolution reflects the temperature sensitivity of a monocular thermal imaging camera, the smaller the temperature resolution of the monocular thermal imaging camera the more obvious the perception of temperature changes, try to choose this parameter value of small products.
Simply put, the smaller the spatial resolution value of the monocular thermal camera, the higher the spatial resolution, the more accurate the temperature measurement, the smaller the spatial resolution value, the smallest target to be measured can cover the pixels of the monocular camera, the test temperature that is the true temperature of the target being measured. If the spatial resolution value is larger the spatial resolution is lower, the smallest target being measured can not completely cover the pixels of the monocular thermal camera, the test target will be affected by its environmental radiation, the test temperature is the average temperature of the target being measured and its surrounding temperature, the value is not accurate enough.
The above is the introduction of how to choose a monocular thermal camera. If you need to buy a monocular thermal imaging camera, you can choose our company, we have many kinds of such products. Our company's website is http://www.argustecn.com/, we would love to welcome you and we hope we can have good cooperation.
Resolution is an important indicator of night vision cameras and many optical imaging systems, which affects the ability of optical instruments to identify and observe. The night vision camera needs to be tested for its resolution before leaving the factory. At the same time, long-term use will also reduce the resolution, so the resolution needs to be checked regularly. So what is the relevant information about the resolution of the night vision camera? Let's take a look at it next.
Here is the content list:
Detection principle
Measures to Improve Positioning Accuracy
The basic principle of automatic resolution detection of night vision cameras is: firstly, locate the resolution pattern, then judge whether the resolution pattern is distinguishable according to the objective criterion of the resolution, and determine the resolution of the instrument according to the judgment result. Resolution auto-detection is performed as follows:
First, a camera is used to capture an image of a special resolution target plate, and the image is preprocessed. Then, the transformation algorithm is used to detect the positioning lines in the image. According to the positions of the four positioning lines, the position of the center of the resolution pattern in the whole image, the size of the pattern, and the inclination can be obtained. A resolution pattern consisting of stripes with equal spacing and the same direction is extracted, the contrast of each pattern is calculated, and whether the area is distinguishable is judged according to the size of the contrast. Contrast is calculated starting from the pattern with the widest line and working downward until it reaches an indistinguishable pattern. For the left and right resolution patterns in the same group, the one with low contrast is used as the contrast of the group of patterns. Take the number corresponding to the previous set of patterns of the indistinguishable pattern as the resolution of the night vision device under inspection. If the first group of resolution patterns is unqualified, it is determined that the resolution of the night vision device is lower than the corresponding value of this group; if the last group of resolution patterns is still distinguishable, it is determined that the resolution is higher than the corresponding value of this group. To achieve the purpose of automatic detection, it is necessary to study the objective criterion of night vision camera resolution and the method to improve the positioning accuracy.
For the image of the night vision camera resolution target board, the pixels on the image can be divided into three categories: pixels in the resolution pattern area, pixels in the positioning line, and pixels in the noise. For noise pixels, it can be removed by opening operation; for pixels in the resolution pattern area, to achieve a good removal effect, you can first perform an opening operation on the entire image to remove the positioning line; then expand the image to appropriately expand the night vision camera resolution pattern area, and finally invert the image and the original image and perform AND operation with the source image to remove the resolution pattern area well. At this time, an image with only four positioning lines can be obtained, and high detection accuracy can be obtained by detecting this image. Since the night vision device belongs to an electronic imaging system, it will have a lot of random noise. Even when the human eye directly observes the image, it will find that there is noise and flickering in the image. This directly leads to the uneven brightness of the image, which will seriously affect the image positioning accuracy.
To reduce the influence of this factor, the method of taking the average of multiple images is adopted. After averaging, the noise in the image is significantly reduced, and the positioning line becomes very uniform, which is convenient for target segmentation and positioning. After several times of positioning the average results of different numbers of images, with the increase of the number of participating average images, the positioning accuracy shows a trend of improvement. When the number of averaged images reaches about 10, the positioning accuracy is basically below 2 pixels. Continuing to increase the number of images has little effect on its accuracy and will slow down the detection speed. Since the positioning accuracy is related to the number of images involved in averaging, the number of pixels occupied by each resolution pattern area is more than 90 × 90, and the pixels of the pattern boundary are removed in the final contrast calculation. (80% of the pixels are taken from the positioning center for contrast calculation), so a positioning error of 2 pixels will not affect the contrast calculation. Therefore, the average result of 10 images is taken in the program to achieve positioning. When the human eye directly observes the target through the night vision device, the image seen still has such electronic noise. To ensure that the detection result is consistent with the image observed by the human eye, the night vision camera resolution pattern area in a single image is still used. Perform resolution interpretation. To further reduce the detection error, in the contrast calculation of the night vision camera resolution pattern area, 80% of the pixels are taken from the positioning center for contrast calculation, excluding the influence of the pixels at the edge of the resolution pattern.
The above is the relevant information about the resolution of the night vision camera. If you are interested in the night vision camera, you can contact us.
Because thermal imaging is a passive, non-contact detection and identification of targets, it is concealed and undetectable, thus making long range thermal camera safer and more effective for operators. Apart from that, do you know what other advantages thermal scope has to offer? Let's take a look at them in detail. Here are some answers.
Here is the content list:
The long range thermal camera is highly detectable and works over long distances.
The long range thermal camera is a true 24/7 surveillance system.
long range thermal camera visualizes the temperature field on the surface of an object, independent of bright light.
The long range thermal camera is highly detectable and has a long-range of action. Using infrared thermal imaging technology, it can be used to see beyond the range of enemy defensive weapons and has a long range of action. Handheld and light-weapon mounted thermal scopes allow the user to see the human body at distances of over 800m; they can be used at distances of 2 to 3km for targeting and firing; onboard ships, they can observe the water up to 10km, in helicopters at 15km they can detect the activities of individual soldiers on the ground, in reconnaissance aircraft at 20km they can detect crowds and moving vehicles on the ground, and they can analyze changes in seawater temperature to detect underwater submarines, etc. The thermal scope can detect underwater submarines by analyzing changes in seawater temperature.
Infrared radiation is the most widespread radiation in nature, while the atmosphere and smoke clouds absorb visible and near-infrared light, but are transparent to infrared light from 3 to 5 μm and 8 to 14 μm, which are known as the "atmospheric window" for infrared light. These two wavelengths are known as the "atmospheric window" for infrared light. They enable clear observation of the target in the night when there is no light at all, or in harsh conditions such as rain or snow, where there is a lot of smoke and clouds. Thanks to this feature, the long range thermal camera can truly be used for 24/7 monitoring.
The thermal imaging technology visualizes the temperature field on the surface of the object, independent of glare, and allows monitoring in the presence of obstructions such as trees and grass. Whereas an infrared thermometer can only display the temperature value of a small area or point on the surface of an object, thermal scope measures the temperature at all points on the surface at the same time and visualizes the temperature field on the surface of the object and displays it in the form of an image. Since the long range thermal camera detects the amount of infrared heat radiation energy of the target object, it is not affected by bright light, unlike a mic-voluminous intensifier which can appear as a halo or shut down when in bright light.

The thermal camera uses an infra-red detector and an optical imaging objective to receive a graphic representation of the infra-red radiation energy distribution of the target to be measured, which is reflected on the photosensitive element of the infra-red detector, thus obtaining an infra-red thermal image that corresponds to the heat distribution field on the surface of the object. This thermal image corresponds to the heat distribution field on the surface of the object. Next, let's take a look at the structure and applications of the thermal camera. Here are some answers.
Here is the content list:
The structure of the thermal camera.
Applications of the thermal camera.
The thermal camera usually consists of an optical unit, a focusing (zoom) unit, an internal non-uniformity correction unit (hereinafter referred to as the internal correction unit), an imaging circuit unit, and an infrared detector (chiller) unit. The optical assembly consists mainly of the infrared objective lens, which converges the thermal radiation of the scene, and the structural component, which supports and protects the relevant group of components. The focus (zoom) unit consists of a servo mechanism and a servo control circuit, which realizes the focus and field of view switching of the infrared objective lens. The internal calibration component consists of the internal calibration mechanism and the internal calibration control circuit and is used to achieve the internal (non-uniform) calibration of the thermal imaging camera. The imaging circuit assembly usually consists of the detector interface board, the main processing board, the chiller driver board, and the power supply board, which together realize the functions of power-up control, signal acquisition, signal transmission, signal conversion, and interface communication. The infrared detector (chiller) component converts the infrared radiation transmitted by the infrared objective into an electrical signal.
Firstly, thermal camera monitors generators and motors for unbalanced loads, high bearing temperatures, heating of carbon brushes, slip rings, and collector rings, shorted or open windings, blocked cooling lines, overloads, and overheating. Secondly, thermal scope allows maintenance checks to be carried out on electrical equipment. It is also useful for security, roof leak detection, environmental protection, energy-saving, non-destructive testing, forest fire protection, medical inspection, quality control, etc. Thirdly, the thermal scope can monitor sudden changes in the natural environment such as volcanic eruptions and landslides. Fourthly, thermal camera monitors transformers for bushing overheating, overload, loose connectors, poorly blocked cooling tubes, poor contact, unbalanced three-phase loads, etc. Fifthly, thermal scope monitors electrical installations for poor contact, overload, loose connections or overheating, unbalanced loads, etc. The applications of thermal scope are becoming more and more widespread and will play a significant role in the research, medical and electronics industries.
