In order to facilitate image recognition and artificial intelligence technology in the traditional measurement indus-try,a non-touch-based AprilTag image recognition method is proposed,and multi-group experiments are carried to study the effect that the observation distance,camera pitch angle,navigation angle exert on Tugen control measurement accura-cy. from. Experiments show that in the cases of robot cam-era α∈(-7.4°,10.6°),pitch angle β∈(-8.9°,9.9°),the dis-tance L∈(250mm,300mm)between the camera center and the center of the AprilTag image,the integrated error of AprilTag image recognition is E<0.4,which proves that the identification effect is good. The coordinate measurement er-ror of the robot camera's X-axis,Y-axis,Z-axis can be con-trolled in millimeter level. This paper verifies the feasibility of this method.
