Combined measurement method for initial installation and adjustment of optical-mechanical system

The invention discloses a combined measurement method for initial installation and adjustment of an optical-mechanical system, and relates to the technical field of optical-mechanical system installation and adjustment. The combined measurement system comprises a laser tracker, three theodolites and a PSM (Pulse Scientific Modulation) adjustment microscope; the combined measurement method comprises the following steps: placing a target module at a theoretical position according to mechanical positioning; establishing a global coordinate system through a laser tracker, and determining the space coordinate of the curvature center of the target module under the global coordinate system; a cooperative target ball of the laser tracker is placed at the space coordinate position of the curvature center of the target module; adjusting the PSM installation and adjustment microscope to a cooperative target ball of the laser tracker for auto-collimation; and based on a global measurement network established by three the
