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.
