1. A method for processing a point cloud of an object, the method comprising:
scanning, by a scanning device, a worktable from a plurality of angles, the worktable having a plurality of points labeled thereon, and the plurality of angles achieved by rotating the worktable at a predetermined angle of rotation; obtaining, from the scanning device, a plurality of sets of points scanned by the scanning device, each set of points corresponding to one of the plurality of angles of the worktable, and each point of each set of points corresponding to one labeled point of the plurality of points of the worktable; determining a positional relationship between every two adjacent sets of the plurality of sets of points; calculating, according to the positional relationships, a transformation matrix of the plurality of sets of points; scanning, by the scanning device, an object placed on the worktable from the plurality of angles to obtain a plurality of point cloud sets of the object; obtaining, from the scanning device, a coordinate point of each point in each of the plurality of point cloud sets; aligning each point cloud set to a same visual angle according to the transformation matrix; combining the point cloud sets according to the transformation matrix to obtain an overall point cloud of the object; determining overlapping points of the overall point cloud; and removing the overlapping points to obtain a simplified point cloud. |
