Laser rangefinder point cloud

Abstract

The article presents a technology for measuring distances by emitting light (laser) and measuring the return time of this reflected light to the receiver. For this, modern devices are used — LIDARs, which are an active optical rangefinder. The architecture of the *.las file linker forming point clouds based on LIDAR data has been developed. The parameters that are measured by the LIDAR system and are the basis of *.las files have been considered. The structure and content of files with arrays of LIDAR data points have been studied. The result of the work is the development of an algorithm used to synthesize a 3D model of a scanned area and select the image of the desired object based on the cloud of environmental points. The advantage of the proposed method is the high accuracy of object detection (several centimeters at a distance of 100 meters) along with its versatility, which allows it to be used for a wide range of applications.
