Point Cloud Data Preprocessing Based on the Geomagic

摘要

In the acquisition process of point cloud data, there exist speckles and noise point. This essay, based on geomagic, presents specific technical steps to remove isolated point in vitro, avoid point cloud resampling and remove point cloud noise. Applications showed that geomagic can, from the original point cloud process, find out useful point cloud, delete speckles, and through the methods of resampling and noise reduction processing, improve cloud quality and reduce data deviation thus improving the data processing efficiency.
