查询词典 geometric

The root-cause for the synchronous error of multiple axes of the vehicle panoramic sight platform was found after analysis with the geometric method. Since the synchronous error is caused by the windage angle produced in the working process of the optoelectronic platform, the method to correct the angular deviation at any distance is proposed. The experiment for solving the problem was implemented. The experiment indicates that the method is valid.
