Abstract

The embodiment of the invention discloses a calibration method and device for a cubic prism group, relates to the technical field of aerospace, and mainly aims to solve the problem that the mechanicaltest cost of the cubic prism group is high. According to the technical scheme, the method comprises the steps of calculating a first coordinate value corresponding to a first cubic prism and a secondcoordinate value corresponding to a second cubic prism according to a light spot returned to a light spot image plane image by a cubic prism group; adjusting the position of the light spot reflectedto the light spot image plane image by the first cubic prism after the mechanical test, enabling the first coordinate value before the mechanical test to be consistent with the first coordinate valueafter the mechanical test, and calculating a third coordinate value corresponding to the second cubic prism; and determining whether a difference value between the second coordinate value and the third coordinate value is smaller than a preset error threshold value or not.

Description

technical field [0001] The embodiments of the present invention relate to the field of aerospace technology, in particular to a method and device for calibrating a cube prism group. Background technique [0002] With the development of communication technology, the promotion and application of artificial satellites have also developed rapidly. Artificial earth satellites are also called artificial satellites. At present, artificial satellites are the fastest-growing and most versatile spacecraft. [0003] Collimation measurement is required before the launch of the satellite to ensure the precise direction of the satellite launch, and the collimation measurement requires mechanical testing of the stability of the cubic prism group, and when the stability of the cubic prism group is mechanically tested, The need to use an expensive theodolite directly leads to a great increase in the cost of mechanical testing of the cubic prism group. Therefore, how to reduce the cost of me...
