E-3DTrack

This repository is for the CVPR 2024 paper "3D Feature Tracking via Event Camera". This work is inspired by the great success of "Data-Driven Feature Tracking for Event Cameras" (CVPR 2023 Best Paper Candidate) and extends it to 3D.

Requirements

1. Python 3.8 with the following packages installed:
   • einops==0.4.1
   • kornia==0.6.7
   • opencv-python==4.6.0.66
   • torch==1.9.0
   • tqdm==4.64.0
2. cuda
   • CUDA enabled GPUs are required for training. We train our code with CUDA 11.1 V11.1.105 on A100 GPUs and test on NVIDIA 3090 GPUs.

Data preparing

1. Our E-3DTrack dataset could be downloaded from https://github.com/lisiqi19971013/event-based-datasets.
2. Download the pre-trained model from https://drive.google.com/file/d/1Gx0zhIeciHGEqrRryPmAC-mqoNO1wuMQ/view?usp=sharing or from https://pan.baidu.com/s/1ONvkUyk2cqWM2XR_XwaKeg (extract code: 2024).

Evaluation

1. Modify the variables "ckpt_path" and "data_folder" in the file "eval.py" accordingly.

Run the following code to generate output results.

>>> python eval.py

The output predictions could be found at "./output"

2. Calculate metrics using the following code.

>>> python calMetric.py
