Automatic zero calibration system and method for photoelectric stabilized platform

An automatic zero calibration system for a photoelectric stabilized platform comprises a master inertial navigation module for a plane, an IMU module, an inertial navigation calculation module, and acontroller. The invention further provides an automatic zero calibration method for the photoelectric stabilized platform, which is based on the automatic zero calibration system for the photoelectricstabilized platform. The automatic zero calibration system and method for the photoelectric stabilized platform has the advantages that the added inertial navigation calculation module can calculateattitude angle information of the photoelectric stabilized platform through navigation information output by the master inertial navigation module for the plane and triaxial angular velocity information output by the IMU module, and outputs the attitude angle information to the controller; the photoelectric stabilized platform is controlled by the controller to rotate until the heading angle and the pitch angle of the photo
