Hidden space point coordinate mirror image measurement method

The invention discloses a hidden space point coordinate mirror image measurement method. The method comprises the following steps: 1, reasonably arranging a reflector and a reflector surface calibration tool; 2, at least three taper holes are formed in the reflecting mirror surface calibration tool; 3, correspondingly placing a target ball of a laser tracker on the taper hole, and measuring the coordinate value of the mark point; 4, adjusting the hole of the target ball, and measuring the mirror image coordinate value of the mark point; 5, calculating a coordinate value of a central point; 6, calculating a space plane where the mirror surface of the reflector is located; 7, measuring coordinate values of mirror image points of the hidden points; 8, drawing a vertical line of the space plane through the mirror image point; 9, calculating a vertical point CZ coordinate value of the vertical line; and 10, extending the vertical line, and calculating the actual coordinate value of the hidden point.
