Please visit link for our new work MVDeTr, a transformer-powered multiview detector that achieves new state-of-the-art!

Overview

We release the PyTorch code for MVDet, a state-of-the-art multiview pedestrian detector; and MultiviewX dataset, a novel synthetic multiview pedestrian detection datatset.

MultiviewX dataset

Using pedestrian models from PersonX, in Unity, we build a novel synthetic dataset MultiviewX.

MultiviewX dataset covers a square of 16 meters by 25 meters. We quantize the ground plane into a 640x1000 grid. There are 6 cameras with overlapping field-of-view in MultiviewX dataset, each of which outputs a 1080x1920 resolution image. We also generate annotations for 400 frames in MultiviewX at 2 fps (same as Wildtrack). On average, 4.41 cameras are covering the same location.

Build your own version

Please refer to this repo for a detailed guide & toolkits you might need.

MVDet Code

This repo is dedicated to the code for MVDet.

Dependencies

This code uses the following libraries

• python 3.7+
• pytorch 1.4+ & tochvision
• numpy
• matplotlib
• pillow
• opencv-python
• kornia
• matlab & matlabengine (required for evaluation) (see this link for detailed guide)

Data Preparation

By default, all datasets are in ~/Data/. We use MultiviewX and Wildtrack in this project.

Your ~/Data/ folder should look like this

Data
├── MultiviewX/
│   └── ...
└── Wildtrack/ 
    └── ...

Training

In order to train classifiers, please run the following,

CUDA_VISIBLE_DEVICES=0,1 python main.py -d wildtrack

This should automatically return evaluation results similar to the reported 88.2% MODA on Wildtrack dataset.
