Morphology-based Scattered Point Cloud Contour Extraction
Slicing technology and morphological operators are employed to extract contour feature from scattered point cloud.Through slicing,unorganized point with high density can be transformed into point sets on a series of plane layers.Raster structure of digital image is utilized to organize sliced point cloud to generate binary images.Then morphological operators are employed to extract contour pixels.The contour pixels are transformed back to contour points,and B spline fitting is done to generate contour feature.The experiment results show that this method can produce high quality result and overcome the multi-loop problem.
