[0048] The present invention will be further described below in conjunction with the accompanying drawings.
[0049] Figure 2 to Figure 5 As a result of the experiment, the abscissa is the image frame number, and the ordinate is different image non-uniformity description parameters. When utilizing the first step of the present invention to carry out parameter estimation in the experiment, select four different temperature points T 1 , T 2 , T 3 , T 4 They are 15°C, 25°C, 40°C, and 55°C respectively. The infrared images to be corrected at the temperature point T are processed, and the values of the temperature T are 20°C, 50°C and 40°C respectively.
[0050] figure 2 (a) is the change curve of the gray mean square error of the infrared image sequence at 20°C, the left picture is the result before correction, and the right picture is the result after correction; figure 2 (b) is the non-uniformity change curve of the infrared image sequence at the temperature point of...
