Deformation monitoring method and system for measuring robot

The invention discloses a deformation monitoring method and system for a measurement robot, and the method comprises the steps: obtaining no less than five observation reference points of the measurement robot, judging the stability of the observation reference points, removing unstable observation reference points, and keeping stable observation reference points, the method comprises the following steps: periodically observing a monitored object based on a stable observation datum point to obtain observation data, establishing an EM algorithm model, estimating missing data in the observation data based on the observation data to obtain a complete observation data value, and finally analyzing a deformation result of the monitored object according to the complete observation data value. The technical effects of processing the deformation monitoring missing data of the measurement robot and improving the accuracy of the deformation monitoring result are achieved. 本发明公开了一种测量机器人的变形监测方法和系统，包括：获取测量机器人的观测基准点，其中，观测基准
