Precision measurement method based on complex irregular shape precise measuring lens

The present invention discloses a spacecraft precision measurement method based on a complex irregular shape precise measurement lens. According to the method, through setting a complex precise measuring mirror, the precise measuring optical path in closed cabin interior equipment is led out, and the precise measurement of the high precision equipment in the closed cabin in a whole machine closed cabin state is realized. According to the method, the precision measurement state of the high precision equipment and a flight state converge, the precision error of a traditional closed spacecraft brought by measuring cabin interior equipment in a cabin opening or cabin segment pull state is eliminated, and the effectiveness of precision measurement data is ensured. 本发明公开了种基于复杂异形精测镜的航天器精测方法，该方法通过设置复杂的精测镜面将密闭舱内部设备的精测光路引出，从而实现密闭舱体内高精度设备在整器合舱状态下的精度测量。该方法可以使高精度设备的精测状态与飞行状态趋于致，消除了传统密闭航天器在开舱门或分舱段拉高状态下测量舱内设备带来的精度误差，保证了精测数据的有效性。
