摘要: Accessibility analysis represents one of the most critical tasks in inspection planning. This determines those probe orientations that can touch an point without collision. paper presents a methodology based on part discretization and application space partitioning techniques (kd-tree) order to reduce number intersection tests between part. A STL model has been used for discretizing set triangles, which permits developed system any type part, regardless its shape complexity. Likewise, recursive ray traversal algorithm speed up kd-tree hierarchical structure calculate exclusively each orientation with triangles potentially interfere it. In further step analysis, real geometry considered. Hence, simplified co...
