Recent advances in 3D acquisition technologies have lead to scanning devices capable of capturing point-based representations of complex objects and environments in a matter of minutes. The resulting models typically consist of many thousands or even millions of individual 3D points and are commonly known as point clouds. However, the loss of edge features of industrial parts after such simplification reduces reconstruction accuracy. point Edge Detection in Unorganized 3D Point Cloud Our method is designed to cope with line segment extraction for large-scale unorganized point clouds from the real word. A line segment here is defined as the intersection of two half-planes. To extract the line segment, we take into account the point region that is near the straight linear structure.
