| description | The invention relates to a multichannel non-uniformity correction method and system of an infrared test system. The multichannel non-uniformity correction method comprises the following steps: inputting a first excitation signal to the infrared test system; converting the first excitation signal into an image area array, and obtaining an AD value mean value of pixel points in the image area array; inputting a second excitation signal to the infrared test system; converting the second excitation signal into an image area array, and obtaining an AD value mean value of pixel points in the image area array; obtaining a gain coefficient according to the average value of the AD values of the pixel points in the image area array; and performing non-uniformity correction on the current signal data input by the corresponding signal transmission channels according to the gain coefficients of the different signal transmission channels. The signal data is compensated through the gain coefficient of the signal transmissio |
