DenseMatchingBenchmark

This project aims at providing the necessary building blocks for easily creating dense matching models, e.g. Stereo Matching, Scene Flow using PyTorch 1.2 or higher.

Introduction

Our architecture is based on two wellknown detection framework: mmdetection and maskrcnn-benchmark. By integating their major features, our architecture is suitable for dense matching, and achieves robust performance！

Major features

• Modular Design

  We decompose the matching framework into different components and one can easily construct a customized matching framework by combining different modules.

• Support of multiple frameworks out of box

  The toolbox directly supports popular and contemporary matching frameworks, e.g. AcfNet, GANet, GwcNet, PSMNet, GC-Net etc.

• visualization

  The toolbox provides various visualization, e.g., cost volume / distribution visualization, colorful disparity map and so on.

• State of the art

  The toolbox stems from the codebase developed by AcfNet team who ranked 1st at KITTI 2012 and 3rd at KITTI 2015 in 2019, and we keep pushing it forward.

Highlights

• Multi-GPU training and inference
• Mixed precision training: trains faster with less GPU memory on NVIDIA tensor cores.
• Batched inference: can perform inference using multiple images per batch per GPU

Installation

Please refer to INSTALL.md for installation and dataset preparation.

Get Started

Please see GETTING_STARTED.md for the basic usage of DenseMatchingBenchmark.

TODO

• [x] inference
• [x] visulization tool(for cost volume)
• [ ] unsupervised mono-depth
• [ ] unsupervised stereo

Experiment Results

All our reimplemented methods will provide checkpoint(including all training details, e.g., TensorBoard Record) in corresponding config file ResultOf{ModelName}
