Title:
赤色立体地図画像を用いた点群種類推定装置及び赤色立体地図画像を用いた点群種類推定プログラム
Document Type and Number:
Japanese Patent JP6993644
Kind Code:
B2
Abstract:
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
