Embodiment 1
[0034] see figure 1 , this embodiment discloses a method for extracting plane round holes of prefabricated components based on point cloud data, comprising the following steps:
[0035] 1) Input the point cloud data of the plane with round holes in the prefabricated components.
[0036] 2) Process the point cloud data input in step 1) with an edge extraction algorithm to obtain a list of edge points including inner edges and outer edges.
[0037] 2.1) Calculate a certain number of nearest neighbor points for each point.
[0038] 2.2) If figure 2 As shown, take each point as the center, divide its neighborhood into eight equal angles, and judge whether all of the eight areas fall into the nearest neighbor of the point, if not, mark the point as an edge point. In particular, by controlling the number of nearest neighbors, different classes of edge points can be obtained. see Figure 4 , according to the number of point clouds in the specific implementation example, when ed...
