Polygonization of point clouds of repetitive components in civil infrastructure based on geometric similarities

[Display omitted] •We propose a method for polygonizing from a point cloud based on similarity.•Our method uses shape matching to find similar components in point cloud.•Template models are arranged into the similar regions found by shape matching.•The template models are either in point cloud or cr...

Zusammenfassung:	[Display omitted] •We propose a method for polygonizing from a point cloud based on similarity.•Our method uses shape matching to find similar components in point cloud.•Template models are arranged into the similar regions found by shape matching.•The template models are either in point cloud or created by photogrammetry or CAD.
