Research on the key technology of laser scanning data post-processing
Abstract:Three-Dimensional laser scanning technique which has been widely used in various fields is the latest technology of the entire three-dimensional data acquisition and reconstruction of technical systems. However, the follow-up data processing of three-dimensional laser scanning is a very complex content. This paper first int roduces the system composition and the working principle of 3D laser scanner , and then point s out the procedure and methods to process the point s cloud,Furthermore,the use of advantages and disadvantages of various methods of model simplification has been analysed and compared in detail and the result of this approach are int roduced with a factual example.
Keywords: Terrestrial 3D Laser Scanning Technique Unorganized Cloud Points Point Cloud Registration model simplification
