Claim 1:
2. The method according to claim 1, wherein the establishing the modeling coordinate system taking the three-dimensional towered checkerboard as a basis, and generating the simulated point cloud of the three-dimensional towered checkerboard comprises:
by taking a bottom left protrusion of the three-dimensional towered checkerboard as an origin, along a distribution direction of the three-dimensional towered checkerboard, respectively establishing an x-axis, a y-axis and a z-axis, to establish the modeling coordinate system; and
generating the simulated point cloud of the three-dimensional towered checkerboard under the modeling coordinate system according to structure information of the three-dimensional towered checkerboard, with a point spacing of the simulated point cloud being less than 1 mm.
