Makescene error #536

Closed Dhananjay777 closed 3 years ago

Dhananjay777 commented 3 years ago

Hi,

I am trying to run ,,mve'' on WSL 2. When I execute the 'makescene' command the following error shows up ''makescene: command not found ''. Please advise on this

Thanks Dhananjay

Did you also build the apps? In that case, you'd probably have to run something like ./apps/makescene/makescene. Or if you're already in the apps/makescene/ directory, you have to run it by typing ./makescene.

Thanks a lot that did it. Additionally I am wanting to run MVE on a synthetic dataset (blender). So for the Sfm to work I guess the focal length has to be entered into meta.ini for each image ? Is that it?

simonfuhrmann commented 3 years ago

If you're running on a synthetic dataset, do you need SfM at all? You can just import calibrated images directly.

Dhananjay777 commented 3 years ago

Yes, ok so I am basically looking for the 3D dense point cloud. Then maybe directly proceed from the Multi-View Stereo step onwards. The synthetic camera images are of size 400x400 and the camera setting used has a 39.6 deg fov. This yields a horizontal and vertical focal length of 555. So could please clarify how I could import this data for that step. Thanks

Look at the directory/file structure of an existing scene that already ran sfm. You have to set the principal point to (0.5, 0.5) and the focal length to 555/400 = 1.3875 in the meta.ini file. Then you have to generate features for MVS to work, there is a tool for that called featurerecon in the apps/ directory. After that proceed with MVS as outlined in the users guide (in the wiki). Also consult the users guide for details on the file formats.
