Multi-scale region growing point cloud filtering method based on surface fitting
Aiming at the problem of over-erosion and type II error accumulation by progressive triangle irregular network(TIN) densification(PTD), a multi-scale filtering method based on region growing is proposed. This method introduces pyramid strategy to establish different levels of point cloud, in which t...
