Hello,
I am working with CapturingReality and I get good results pretty quickly, which I am quite happy about.
Yet the resulting models all have excessive geometry in comparison to the pointcloud.
I was wondering how to get rid of that excessive geometry?
Example:
What is the preferred workflow to get rid of these superficial polys?

Hello,
Usually by using a reconstruction region (and reconstructing the model again) or by the filtering tool.
By the way, the software is called RealityCapture. Capturing Reality is the name of the company.
A tight bounding box will remove a bit, but with the example you’ve given you’ll need to put it in another piece of software and manually remove the polygons if you’re trying to tighten up the excess down to the bricks on the building.
For simple clean-up there are a ton of options, I found the free Meshmixer to be pretty speedy in removal and some basic reconstruction…
You can simplify the reconstructed mesh with the “Simplify” tool. Just choose a target triangle count, and click on “Simplify”.
You will need to retexture the model after.
If you can, try getting some pictures from a viewpoint looking down upon the top of the structure. That way RC has information how the actual shape goes on behind where it can’t “see” in your original dataset and thus it can invalidate the pieces of sky you have as extra polygons in your reconstruction.
You will still get excess polygons but the immediate problem you are showcasing will be mostly fixed.
