Point cloud distribution visualization device, point cloud distribution visualization method, and point cloud distribution visualization program

摘要

PROBLEM TO BE SOLVED: To provide a point cloud distribution visualization device capable of creating a point cloud distribution visualized image which is a color image in which a distribution state of a point cloud representing a surveying object is expressed by color difference from three-dimensional point cloud data. A point cloud distribution visualization device 100 calculates a normal vector calculation unit 110 that obtains a normal vector n of a point cloud from three-dimensional point cloud data, and angles θ and φ of a normal vector n with respect to a horizontal plane or a vertical plane. It has an angle calculation unit 120 to be obtained, and a point cloud distribution visualization unit 130 that generates a color image G in which each part of the survey target is colored according to the angles θ and φ.
