Pose error compensation system and method for tower-mounted optical measurement device

The invention provides a system and a method for compensating the pose error of a tower-mounted optical measurement device, which can solve the problem that the existing error compensation system and method are not suitable for an optical measurement device arranged at the top of a lifting tower with a certain height. The system comprises a base plate, a rotary table, a pose monitoring camera, a self-positioning module, an optical measuring device and at least four azimuth marks located in a view field of the pose monitoring camera, and the rotary table is used for driving the optical measuring device to turn to an object to be measured and giving an azimuth angle and an elevation angle of the optical measuring device relative to the object to be measured. The pose monitoring camera is used for acquiring an image of each azimuth mark in real time, the self-positioning module is used for acquiring a plane coordinate of the optical measurement device in real time, and an included angle formed between the azimut
