【摘要】：飞机失事的事故率较低,但损失一般较为严重。对飞机残骸现场的有效记录,能够帮助我们了解失事场景,并进行后续分析,但国内外相关研究较少。本文利用一套LiDAR系统对事故现场进行测绘和三维尺度图像信息保存。并结合改进的ICP算法实现了更高精度的点云拼接,从而对失事前后的同一部件进行对比分析,以确定其受力和变形情况,进而帮助确定失事原因。与其他飞机失事场景记录方法相比,该系统三维重现效果更好。
[Abstract]:The accident rate of plane crash is low, but the loss is usually serious. The effective record of the aircraft wreckage site can help us to understand the crash scene and carry on the follow-up analysis, but there are few related researches at home and abroad. In this paper, a LiDAR system is used to map the accident site and preserve the 3D image information. Combined with the improved ICP algorithm, a higher precision point cloud splicing is realized, so that the same component before and after the crash is compared and analyzed to determine the force and deformation of the component, and then to help determine the cause of the crash. Compared with other aircraft crash scene recording methods, the 3D reconstruction effect of the system is better.
