Title:
POINT GROUP DATA PROCESSING DEVICE, POINT GROUP DATA PROCESSING METHOD, AND POINT GROUP DATA PROCESSING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2011/070927
Kind Code:
A1
Abstract:
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.
