A scheme to calibrate FY-4 high-precision dynamic goniometry system based on high-resolution imager is introduced. The program uses the imaging method to obtain the standard template image projected from the goniophotometer system. Combined with the image evaluation software, the comprehensive performance of the goniometry system is given qualitatively to assist in the calibration of the goniometry system. High-precision goniometry system is used to measure the pointing accuracy and dynamic scanning accuracy of the scanning mirror in the scanning space remote sensing instrument, which is of great significance to accurately calibrate it. The test results show that this method can calibrate the parameters of the goniometer system and verify whether the various performances of the goniometer system meet the engineering requirements.
