Embodiment Construction
[0077] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0078] Such as figure 1 As shown, a kind of STL digital model generating method based on point cloud rapid reconstruction of the present invention comprises the following steps:
[0079] (1) Extract point cloud features
[0080] First, the voxel grid method is used to down-sample the input point cloud, and the basic characteristics of the point cloud shape are retained when reducing the point cloud scale; then, the statistical analysis method is used to remove measurement noise points from a point cloud dataset; finally The point cloud feature extraction based on the random sampling consistent RANSAC algorithm is used to extract a subset of point clouds that meet the requirements. The flow chart of the algorithm is as follows figure 2 As shown, the specific steps include:
[0081] (11) The voxel grid method is us...
