The invention discloses a high-precision laser ranging method for photoelectric equipment, and belongs to the technical field of laser ranging of the photoelectric equipment. The invention particularly relates to a method for realizing high-precision laser ranging by using a timing system synchronizing signal of photoelectric equipment and GPS time information. The photoelectric equipment modulates the received GPS time information into a whole second, generates a timing system synchronization pulse signal of one period, and sends the timing system synchronization pulse signal and the GPS time information modulated into the whole second to the laser subsystem. And after the laser subsystem receives the timing system synchronization pulse signals, timing is carried out between two adjacent timing system synchronization pulse signals, and the precise time in the laser subsystem is calculated according to the timing time and the GPS time of the whole second. When the laser subsystem carries out laser ranging, a
