Specific space measurement method and system based on laser pose target and machine vision

The invention relates to a specific space measurement method and system based on a laser pose target and machine vision, and the method comprises the steps of integrating the laser pose target and a plurality of cameras into a combined body, and measuring the relative relation between the center line and coordinates of the laser pose target and each measurement camera; obtaining the direction difference, the inclination angle difference and the rolling angle difference of the laser pose target relative to the laser beam; obtaining the geodetic coordinates of the center of the laser pose target and the orientation and zenith angle of the laser beam; calculating the exterior orientation elements of the combined body and each measurement camera; using a laser plummet to emit laser spots to the working face to be measured, and using the measuring cameras to shoot the laser spots to obtain images; and using a control terminal to process and calculate the geodetic coordinates of the laser spots, and finally generat
