Mosaic research with 3D lidar point cloud of civil aircraft

Following aircraft accident, reconstruction and splice of wreckage is an important aspect for the survey work. By splicing the wreckage, we can find the most serious damage position and determine the attitude, speed of the aircraft, and so on. It provides effective technical support to accident investigation. However, wreckage splice is very difficult and needs large of time and funds. With development of computer and measurement technology, 3D wreckage splice has become been achieved by using computer. By using 3D point cloud data of segmentation aircraft, we propose a mosaic method and achieve wreckage splice with improved iterative closest point algorithm in this paper. It will be helpful to investigate the cause of aircraft accident.
