Filtering of Lidar Point Clouds Based on Segmentation

摘要

The filtering algorithm based on image segmentation can be more consideration point cloud of context. It has better robustness. The filtering of edge detection-region growing works on raw Lidar point clouds without previous grid. It can detect the edge depending on spatial topologic relations between points, and obtain the bare ground through the method of region growing according to certain standards. Experiment results of different region show that the algorithm which does not suffer point cloud density, size and shape of buildings, distribution of vegetation has high stability and precision.
