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.
