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.

A Materials Risk Information Platform is being developed under the cooperation of companies and academic societies with NIMS as project core. To combine safety and economy, which are sometimes contrary to each other, it is important to find an optimal solution using a new concept: risk based engineering. A 5-year project, the Materials Risk Information Platform, was started in 2001 in NIMS on the boilers of thermal power plants and the objectives of this project, research areas and its present state were outlined.
