RefineMesh gives specific unexpected results occasionally.
This happens to some photo groups.
after ReconstructMesh, the mesh file is generated correctly. as shown below:
ReconstructMesh -i dense.mvs -o mesh.mvs
but after RefineMesh, the refined mesh breaks into pieces....as shown below:
RefineMesh -i mesh.mvs -o mesh_refined.mvs
This usually occurs at the center of model where most of the details at.
this looks really bad, never saw this before can you share the problem dataset?
Seems like there is a lot of inverted facets (black triangles) at the end of ReconstructMesh. I think it make the refineMesh process being very confused later on.
you can download the problem dataset from: http://www.smallworld-network.com.cn/img/upsidedownhouse.tar.gz
btw, if I rescale the photos down to 1024x768, the problem goes away, but the model loses most of its detail due to low resolution of the images.
Thx, I'll have a look! At what step did you rescale the images? I suggest to try using the full scale images for the entire process, except for the densification step (use --resolution-level 2 or more to scale down the images).
I manually rescaled the data set down to 1024x768, and used that to run the whole process, the problem goes away. After that, I tried 2048x1536, the refined model broke again.
