Embodiment Construction
[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0037] A new K value optimization method in the point cloud clustering and denoising process, the method includes the following steps:
[0038] (1) Use a 3D scanner to scan the outline of the physical model to obtain 3D sampling point data, that is, 3D point cloud data. Due to the limitation of the accuracy of 3D scanning equipment, the influence of light and the reflection characteristics of materials, the point cloud data contains noise; at the same time The sampling point cloud data is also unsatisfactory due to human disturbance or the defects of the scanner itself.
[0039] (2) The point cloud obtained by scanning is used as the clustering sample data, and the upper bound of the search range of the cluster number is determined according to the threshold layering method, and the lower bound is 2, and each integer value within the ...
