摘要：LIDAR systems have come to be extensively used in photogrammetry and mapping sciences. The accuracy of 3D information is mainly affected by navigational and system-dependent uncertainties, but also by the laser beam properties and the nature of the light interaction on the object surface. At the moment, the system-dependent sources of error are much better known than those arising from laser light interaction. In this paper, a simulation approach for scanning LIDAR systems is presented and discussed. Simulating light interaction on an object surface provides an opportunity to measure well-defined objects under controlled conditions. The simulated object remains unchanged over time, and when various sensor and system parameters are applied, it is possible to compare the 3D point clouds created. Furthermore, well-established simulation software makes it possible to study and verify future LIDAR systems and concepts
