Method and device for monitoring motion process of space manipulator

The invention provides a method and a device for monitoring a motion process of a space manipulator. The method comprises the following steps of: determining a plurality of motion process intermediate points for executing a target task by the space manipulator; constructing a simulation motion track sequence of the space manipulator; constructing an actual motion track sequence of the space manipulator; performing fitting degree analysis on the simulation motion trail sequence and the actual motion trail sequence; based on a joint point detection model of the space manipulator, the priority of image data shot by a plurality of monitoring cameras in the current space manipulator motion task process is analyzed, and a main monitoring camera is determined according to the priority; the spatial position of the mechanical arm is calculated through the multiple movement process middle points and projected to an image plane shot by the main monitoring camera, and the calculated value of the spatial position of the m
