The Research Of Three-dimensional Laser Radar Measurement Technology

Three-dimensional laser radar measurement technology, through the laser transmitter and receiver, and the use of global positioning systems and inertial navigation system, quick access to spatial data object to be detected. Recent progress at home and abroad, the laser radar scanners, POS systems, high-definition cameras and other equipment for the development of an integrated set of airborne laser scanning radar acquisition system。access to the corridors of power transmission lines and line three-dimensional laser point cloud, images and other data to achieve synchronization of various data collection, one of the working platform。Are briefly introduced in this paper the three-dimensional laser radar technology background, significance and domestic and foreign development status, and then explained the concept of laser radar system, working principle, system composition and working process, combined with the current development trend of intelligent power grid, focusing on the scope of application of this technology in the field of transmission line construction, operation and maintenance. Then through the concrete implementation of the engineering case, the daily operation and maintenance of the four 500kV transmission line in Ninghai has played a certain role in guiding. Finally, according to the actual demand of the intelligent power grid and the development trend of power system production business integration of this technology in the transmission line running condition assessment, fault analysis, diagnosis, emergency rescue plans and other fields to expand the brief outlook。...
