Requirements

  1. Python version 3.8.5
  2. Pytorch version: pytorch==1.6.0 torchvision==0.8.2 torchaudio==0.7.0 cudatoolkit=10.2.89
  3. pytorch3d version 0.3.0
  4. Cuda version 10.2

Training & Testing

  1. We train M3Depth on SCARED

    • We need to extract images from the videos and rectify the stereo image pairs with the given camera parameters (endoscope_calibration.yaml).
    • Only keyframes were together with accurate depth maps.
    • Sort the absolute image root and save them in $splits/Endovis_origin/train_files.txt.
    • Change the data directory to the folder of data.

  2. Train M3Depth:

    • cd $M3Depth
    • python main.py --mode train

  3. Test M3Depth:

    • cd $M3Depth
    • python main.py --mode test
