Polygons are generated with these captured point-clouds.
「釧路市立博物館・釧根測量設計業協会・RIEGL VUXコンソーシアム・日本写真測量学会：知人石炭桟橋３D計測」(Unable to explain in English.) offered the point-clouds.
「The Point-clouds by Fix Laser and Drone Camera」
The next image represents the point-clouds captured by fix laser system and drone camera.
In order to clarify the shape, points are tremendously reduced.
Color points represent the foundation and no color points indicate the pier ad the railway on it.
The next image represents non-reduced point-clouds of about 0.7million dots for generating polygons.
The next image represents the pier consisting of polygons. The cross lines of points are utilized.
The next indicates the assembly of the pier and its foundation. The foundation is generated with TINs.
Both images can be output as STL format.
