The aerial photographs taken by UAV and the laser scanner measurement data are restored by software as point group data having 3D coordinate values such as terrain / features etc.
* Software used may differ depending on the region. Screen shows one example.
Unnecessary points (noise) such as vegetation in the acquired point cloud data are eliminated using point cloud processing software.
When all the measurement point group data is used, the load in data processing becomes high, so representative points are extracted and the point cloud density is reduced.
TIN (irregular triangulation) is placed a thinned point cloud. Create surface data of terrain and rock segment boundary.
