Abstract: Dual wedge scanning is a broad prospect method of next generation Laser imaging system. Due to the unique scanning mode and imaging characteristics, data of dual wedge Laser imaging system is sensitive to parameters and environment, and it is significant in both theory and application to research its feature of time and space. Based on the imaging principle of dual wedge scanning, the dynamic imaging process was modeled and a simulation system in three-dimensional environment was designed. Based on the imaging principle of dual wedge scanning, the dynamic imaging process was modeled and a simulation system in three-dimensional environment was designed. Then the point cloud data simulated in different scenes of distinct parameters was analyzed in several aspects. The research result can be used to verify the performance of the three-dimensional object detection and recognition algorithms, in addition, it has reference value for design and development of the dual wedge scanning Laser imaging system.
