bundle2pset outputs a `.ply` file without any vertices #543

Closed AnaRhisT94 closed 3 years ago

Hi,

I've used makescene -i IMAGE_DIR SCENE_DIR and sfmrecon SCENE_DIR,

I'm trying to create a .ply object and visualize it in MeshLab, after using the command bundle2pset -F2 I'm getting a .ply format file that weights 300 bytes and I don't see anything in MeshLab (# of vertices is zero)

Output:

Note: When I used smvs, it worked well https://github.com/flanggut/smvs , it says there that: This project is intended as an alternative multi-view stereo step and replaces the dmrecon and scene2pset applications with the smvsrecon

Did sfmrecon succeed in reconstructing the scene? Also, bundle2pset does not accept a -F2 argument. Did you use scene2pset instead?

Yup, I ran again sfmrecon and then tried both scene2pset with F2 and bundle2pset too, it doesn't work.

scene2pset outputs an empty .ply file and bundlet2pset outputs this error:

Can you please provide the console output of sfmrecon?

It does work with dmrecon, smvs also does this process but much better. When doing w/ dmrecon and bundlet2pset it reconstructs a model that doesn't look good, the results of smvs are really good. I'm not sure why sfmrecon doesn't work though. the log file:

Let's clarify a few things here.

bundle2pset outputs the sparse point cloud from SfM, and depending on what your expectations are, that may "not look good". But as I said, it's sparse, not dense.
The workflow for getting these sparse point clouds is makescene -> sfmrecon -> bundle2pset.
scene2pset outputs a dense reconstruction which you can either get through dmrecon or smvs.
The workflow for getting these dense reconstructions is makescene -> sfmrecon -> dmrecon OR smvs -> scene2pset.

Having said that, what exactly is your problem now?
