Ground object spectrum testing method and system based on high-definition 3D scanning

Abstract

The invention belongs to the technical field of electronics and science, and discloses a ground object spectrum testing method and system based on high-definition 3D scanning. The method comprises the steps: selecting a ground object to be measured, and carrying out preprocessing; connecting a 3D scanner with a mobile workstation through a data line and a power line; performing high-precision scanning on an actual ground object by using the 3D scanner to obtain ground object model data segmented by a triangular mesh and storing the ground object model data; extracting normal vector coordinates of each surface element; calculating two azimuth angles theta of the normal vector of each surface element and counting the azimuth angles of all the surface elements to obtain the total number of the azimuth angles of each angle, and then drawing a relational graph of the number of the angles and the corresponding angles; and performing hypothesis testing on the obtained statistical data. The method fills the blank in the field of establishing models based on specific terrain and ground features in China in the current market, and provides a basis for deducing the shape of the ground feature according to the ground feature spectrum.
