摘要/Abstract

摘要： 双光楔扫描是具有广泛应用前景的下一代激光扫描工作体制,由于双光楔扫描具有独特的工作模式和成像特性,其成像数据受参数、环境影响较大,因而对该扫描体制激光成像系统数据的时间、空间特性进行研究具有重要的理论和实际应用价值。针对双光楔扫描机制的成像原理,对双光楔扫描激光成像过程进行三维、动态的建模并设计仿真平台变得十分关键。同时,对不同成像参数及环境条件下的成像数据进行仿真生成点云数据,分析不同场景下扫描数据的成像特性也具有特殊意义。运用仿真结果来验证三维目标检测和识别算法的性能,对双光楔扫描激光成像系统的设计和研制具有参考价值。

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.

Key words: dual wedge, Laser Imaging System, three-dimensional point cloud, dynamic simulation
