摘要/Abstract

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:

Aircraft accidents' rate is low, but the loss is generally serious when it happens. Effect records of the crash site and the wreckage can help follow-up analysis, rebuild the accident scene. But few studies can be found nowadays. In this paper, a LiDAR system is used to map and save the three-dimensional information of the accident scene. Combined with improved ICP algorithm, the point-clouds of aircraft and its wreckage can be registered accurately to analyze the deformation and forces of the components by comparison, which helps to find the cause of the crash. Compared with other methods or systems, this system is of higher accuracy, and achieves better results in three-dimensional reconstruction.
