The invention provides a method for autonomous measurement of the pose of tripod structure of a solar panel on a non-cooperative spacecraft. The method is as below: first providing an autonomous recognition algorithm based on Hough changes of sliding window and characteristic structure of inscribed circle of triangle, so as to obtain the image coordinates of the feature points of the tripod; then calculating the relative pose represented by the rotation matrix and translational matrix by combining with a P4P algorithm and the known dimension and characteristic structure of the spacecraft. The invention is applicable to the relative position measurement in observation, tracking and docking of the non-cooperative spacecraft in a close range rendezvous stage. The invention has the following beneficial effects: the method can automatically complete feature extraction and pose solution of tripod part of the solar panel; the whole process does not require manual intervention or arrangement of marker on the target; and the method has high real-time performance and autonomy, and overcomes the disadvantages of influence of transmission delay and transmission reliability on measurement results under remote control, and instability of system.
