摘要	The extraction method of kinematic formula for a drift adjusting mechanism in space cameras was researched to accurately control the drift adjusting mechanism and to improve the imaging quality. The distribution law of test data for the drift adjusting mechanism was analyzed, and the model of distribution law was built. Based on three-parameter trigonometric function fitting method by use of angular frequency one-dimensional search, the test data were handled by the least square fitting. The distribution law of fitting residual was studied, and the inherent error components were extracted and modified, so that the fitting accuracy was further improved. The test results show that on basis of the kinematic formula of drift adjusting mechanism extracted by the proposed method, the control precision of drift adjusting system is less than 30, equal to that of least square fitting (maximum fitting deviation 20.5107). The kinematic formula also satisfies the requirements of control system, realizes high precision control of the drift angle and reduces the demand for part processing, assembling, and production costs.
