Dynamic calibration method and dynamic calibration system for positioning equipment

The invention discloses a dynamic calibration method and a dynamic calibration system for positioning equipment. According to the system, a differential positioning equipment mobile terminal is placed on a slope of a right triangle slope and can slide along the slope; the rigid ruler is arranged at the upper end of the moving end of the differential positioning equipment, the rigid ruler is parallel to the slope of the right triangle slope, and the rigid ruler is used for accurately measuring the sliding distance of the detected equipment on the right triangle slope; performing difference calculation on the differential positioning equipment base station and the detected equipment, and outputting high-precision differential positioning data; and the camera is arranged above the mobile end of the differential positioning equipment and is used for shooting the scales on the rigid ruler. According to the technical content of the invention, the error condition in elevation calibration of the detected equipment ca
