1. There is weak detail differentiation and low visual contrast.
The contrast of the infrared thermal picture is low, which reduces the capacity to detect details, as the infrared thermal imager relies on temperature difference to image, and the temperature difference of the overall object is not large.
2. Transparent barriers, such as window glass, prevent a clear view of the goal.
Since the infrared thermal imager relies on temperature difference for imaging, and transparent obstacles such as window glass, the infrared thermal imager cannot detect the temperature difference of the object behind it, so it cannot see the target clearly through the transparent obstacle.
3. High cost and expensive
At present, the cost of infrared thermal imager is still the biggest factor limiting its widespread use, but with the emergence of uncooled infrared focal plane arrays, it provides an effective means to obtain high-resolution and high-reliability devices at low cost. With the development of science and technology, the breakthrough of key technologies, and the improvement of processing efficiency, the cost will be greatly reduced in the future.
4. Long-distance monitoring cannot be achieved, and the monitoring screen can only determine whether there are suspicious persons entering, but cannot clearly see the face and appearance characteristics
Thermal imaging cameras are widely used in both military and civilian applications. With the maturity of thermal imaging technology and the advent of various low-cost thermal imaging cameras suitable for civilian use, it plays an increasingly important role in various sectors of the national economy.
