Bathroom scan

A project log for Photogrammetry 3D Scanning

This project is a brief tutorial from acquiring multiple images to a finished 3D print of a real world object.

I've been moving to a new apartment this week and therefore the progress is a bit slow. Besides that I tried a quick scan of my former bathroom.

The picture shows the output of CMVS, therefore the dense point cloud. It's visible that only edges are recognized and walls or other low texture surfaces create nearly no points. The initial photo set is a series of 116 photos with a resolution of 3008x2000. The room wasn't lit very well and therefore the single images had even less feature points.

On the right you can see the tiles on the wall, that should be flat, but due to the low amount of points in the center of the tiles they tend to be shaped like above. The shiny edge of the bath tub couldn't be captured at all and there is a hole inside the wall in the resulting mesh. Overall the mesh quality is quite low and the mesh fits the reality poorly. For a better scan additional indirect lightning would have been necessary to capture fine details on the wall and on the tiles.
