featureless surface depth issue #1660

Open pandahops1 opened 2 years ago

pandahops1 commented 2 years ago

Meshroom works great when there are features on each surface yet I can't get it to work for featureless surface, such as the purely yellow sides of this dishwashing detergent:

Even if I take clear pictures of it lying down on a chess board, Meshroom cannot recover its flat, featureless sides.

Is there any way to get the correct reconstruction for this kind of objects? My current recovery screenshots: mesherr2 mesherr1

https://github.com/alicevision/meshroom/wiki/Projected-Light-Patterns The described workflow can also be used with a automated turntable, capturing one dataset without and one covered by Water Soluble/Temporary Spray Chalk or something similar.

thanks for the response. so you mean i can spray paint pattern onto featureless surfaces? but does resolution of pattern affect the result?

Here is a good tutorial: https://www.3dscanstore.com/blog/3d-scanning-reflective-objects If you can - simply drawing on your bottle will improve the reconstruction. Irregular patterns can help to recover more features. That is why capturing rocks (irregular, matte surface) is so popular for a first project in photogrammetry.

thanks for the answer. (sorry for not responding earlier on my other account)
