Method system and computer program for topographical change detection using LiDAR data

摘要

The present invention is a method for real-time detection of terrain changes using lidar data, and a system therefor, which generates continuous point cloud data having absolute coordinates based on lidar data in real time, removes noise, reduces data, matches data, and By comparing the real-time topography change through the comparative analysis process, the overall processing is simple and the data volume to be processed is significantly reduced, which suggests a method for quickly and effectively detecting the real time topography change.
