Problems solved by technology

[0003] With the widening of the application range, the defects of thermal infrared in the detection of small temperature difference experiments are becoming more and more prominent. Due to the small temperature difference between the damage of the agricultural products itself or the temperature difference between the diseased part and the intact part, the experimental results are easily affected by the environment and cause errors.

[0004] In view of the above problems, the current main method to solve the problem is to heat or refrigerate the agricultural products, and artificial manufacturing errors, but this kind of treatment often causes the destruction of the internal structure and nutrients of the agricultural products, so the control of the temperature and humidity inside the sample chamber is realized. Adjusting and maintaining the temperature and humidity required for the experiment is of great significance to the acquisition of thermal infrared images

[0005] In addition, thermal infrared images need to be collected simultaneously with RGB images during the acquisition process. To ensure that the target sample is collected at the same position and attitude requires the cooperation of multiple sensors. Although some of the existing equipment can achieve RGB images and thermal infrared images The images are shot on the same camera, but due to the differences in the focal length and field of view of the cameras, it is impossible to achieve a complete match of the images, which brings problems to the post-image processing

Moreover, the thermal infrared camera is shooting the target sample room. Due to the different sizes and shapes of the samples, the focus of the camera is not accurate, and the recognition is not clear.
