Describe the bug
I am trying to extract the camera pose and point cloud from the result generated by TextureMesh. I executed python .\MvsReadMVS.py -i D:\repo\openMVS\test\texture.mvs -o D:\repo\openMVS\test\texture.json in the script\python directory, but got an error "error: opening file 'D:\repo\openMVS\test\texture.mvs'". I added breakpoint debugging and found that the reason was that the archive_type variable value parsed was MVS\x00, which resulted in the failure to pass the if archive_type != 'MVSI' judgment in line 78 of the code in MvsUtils.py.If I manually change if archive_type != 'MVSI' to if archive_type != 'MVS\x00' , I get a MemoryError.
I don't know where the problem is. Can you provide some help?

really appriciate.

To Reproduce

  1. Execute the following commands in sequence：
    InterfaceCOLMAP -w D:\repo\openMVS_sample\test -i D:\repo\openMVS_sample\test -o scene.mvs
    DensifyPointCloud -w D:\repo\openMVS_sample\test -i scene.mvs -o test_dense.mvs
    ReconstructMesh -w D:\repo\openMVS_sample\test -i test_dense.mvs -o mesh.mvs
    RefineMesh -w D:\repo\openMVS_sample\test -i mesh.mvs -o refinemesh.mvs
    TextureMesh -w D:\repo\openMVS_sample\test -i refinemesh.mvs -o texture.mvs
  2. Copy texture.mvs to the openMVS\test folder (need to create the test folder manually)
  3. Enter the scripts\python directory
  4. Execute python .\MvsReadMVS.py -i D:\repo\openMVS\test\texture.mvs -o D:\repo\openMVS\test\texture.json

Expected behavior
The MvsReadMVS.py script correctly generates the texture.json file, which contains the camera pose and point cloud data.

after I change if archive_type != 'MVSI' to if archive_type != 'MVS\x00' manually:

Use the initial mvs file (not after texture) or use latest develop branch

thanks for your reply，I can generates the json file now.

one more question, the initial MVS file(scene.mvs) contains a sparse point cloud. If I want to obtain a point cloud after dense reconstruction, what should I do?

I tried running python .\MvsReadMVS.py -i D:\repo\openMVS\test\test_dense.mvs -o D:\repo\openMVS\test\texture.json, but I only got an error.
