POINT GROUP KIND ESTIMATING APPARATUS USING RED THREE-DIMENSIONAL MAP IMAGE, AND POINT GROUP KIND ESTIMATING PROGRAM USING RED THREE-DIMENSIONAL MAP IMAGE

摘要

PROBLEM TO BE SOLVED: To obtain a point group kind estimating apparatus using a red three-dimensional map image which can reduce time and costs because a noise of the red three-dimensional map image is automatically removed.;SOLUTION: A point group kind estimating apparatus comprises an automatic filtering unit 112, a red three-dimensional map generating unit 118, a teacher data generating unit 124, a noise region estimating model generating unit 128, a noise detection removing unit 132, and the like. On the basis of a laser point group obtained by a laser scanner mounted on an air plane for scanning laser irradiated on a ground, a feature other than a foundation which exists upon generation of DEM, that is, features of a noise are leaned by deep learning to detect and remove the noise.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
