[0022] see figure 1 , The device used in the present invention consists of a mount 1, a laser displacement sensor 2, a flat plate 3 and a laser tracker 4. The laser displacement sensor 2 is installed on the mount 1 .
[0023] The steps of the method of the present invention are described in detail below.
[0024] The specific implementation steps of the inventive method are as follows:
[0025] Step 1: Set up the laser tracker 4 on the ground, so that the mounting base 1 and the panel 3 are included in the measurement range of the laser tracker 4;
[0026] Step 2: Fix the mount 1, and the laser tracker 4 measures the three reference holes A, O and B on the mount 1, and establishes the measurement coordinate system OXYZ, where the hole O is the origin, OA is the X axis, and OB is Y axis, determine the Z axis according to the right-hand rule;
[0027] Step 3: Use the laser tracker 4 to measure the three reference holes C, D and E on the plane plate 3, and then establish the ...
