Install with Anaconda

The installation requires Anaconda3. You can create a new Anaconda environment with the required dependencies as follows (make sure to adapt the CUDA toolkit version according to your setup):

conda create --name RAMNET python=3.7
conda install pytorch torchvision torchaudio cudatoolkit=10.2 -c pytorch
pip install tb-nightly kornia scikit-learn scikit-image opencv-python

Branches

To run experiments on Event Scape plese switch to the main branch

git checkout main

To run experiments on real data from MVSEC, switch to asynchronous_irregular_real_data.

git checkout asynchronous_irregular_real_data

Checkpoints

The checkpoints for RAM-Net can be found here:

• trained on EventScape
• trained on MVSEC

EventScape

This work uses the EventScape dataset which can be downloaded here:

• Training Set (71 Gb)
• Validation Set (12 Gb)
• Test Set (14 Gb)

Qualitative results on MVSEC

Here the qualitative results of RAM-Net against state-of-the-art is shown. The video shows MegaDepth, E2Depth and RAM-Net in the upper row, image and event inputs and depth ground truth in the lower row.

Using RAM-Net

A detailed description on how to run the code can be found in the README in the folder /RAM_Net. Another README can be found in /RAM_Net/configs, it describes the meaning of the different parameters in the configs.
