Aircraft skin boundary extraction based on scan line point cloud

点击次数: 所属单位:机电学院 发表刊物:Jisuanji Jicheng Zhizao Xitong 摘要:To improve the extraction efficiency of aircraft skin's boundary feature due to its thin walled structure, an extraction method was proposed based on scan line point cloud, and the influence of points' unequal distribution and the edge's micro chamfering were considered. Feature points extracted from each scan line were used to construct the boundary feature curve. The extraction of feature points included neighbor search, identifying measured points' position and curve fitting. The points were sequenced in the neighbor searching procedure, and surface points and boundary points were distinguished by their discrete curvature. The lines were fitted respectively with points on the surface and side, and the intersection point was taken as the feature point. By extracting feature point beyond the existing measured points, the point cloud density required to ensure the accuracy of feature points was reduced as well as met the design intent. The efficiency and applicability of the method were testified in experiment. © 2017, Editorial Department of CIMS. All right reserved.
