Title: COORDINATE MATCHING METHOD AND APPARATUS FOR THREE-DIMENSIONAL CHECKERBOARD
Abstract:
A coordinate matching method for a three-dimensional checkerboard, the three-dimensional checkerboard comprising at least three mutually perpendicular surfaces. The method comprises: establishing a spatial rectangular coordinate system Oxyz for the three-dimensional checkerboard, setting the three surfaces respectively into an xOy plane, an xOz plane, and a yOz plane; setting the coordinates of key points; and forming a mesh-like array in each plane. Also disclosed is a coordinate matching apparatus for a three-dimensional checkerboard.
