POINT GROUP DATA PROCESSING DEVICE, POINT GROUP DATA PROCESSING METHOD, AND POINT GROUP DATA PROCESSING PROGRAM

摘要

In order to retrieve features of an object to be measured from point group data thereof and automatically generate a three-dimensional shape in a short time, a point group data processing device (1) comprises a non-plane removing unit (16) that removes points of non-plane regions from the point group data of the object to be measured; a plane labeling unit (17) that adds identical labels to points on the same planes other than those removed by the non-plane removing unit (16); a three-dimensional edge retrieving unit (11) that retrieves three-dimensional edges on the basis of at least one of convex envelopes that convexly wrap the planes and intersections of the planes sectioned by the plane labeling unit (17); a two-dimensional edge retrieving unit (12) that retrieves two-dimensional edges from within the planes sectioned by the plane labeling unit (17); and an edge integrating unit (13) that integrates the three-dimensional edges and the two-dimensional edges.
