C++ implementation that extends the original ByteTrack-cpp from 2D to 3D.

Adapted from ByteTrack-cpp (MIT License)

• The implementation is based on ByteTrack-CPP-ncnn that is the official C++ implementation using ncnn
• Only tracking algorithm are implemented in this repository
  • Any object detection algorithm can be easily combined
• Provided as a shared library usable in C++17 or higher
• The output of the implementation has been verified to be equivalent to the output of the ByteTrack-CPP-ncnn
  • Verification data are generated by ByteTrack-CPP-ncnn using YOLOX

• This fork extends ByteTrack-cpp from 2D to 3D (see original overview of ByteTrack-cpp above)
• Kalman filter covariances use defaults from AB3DMOT
• Core tracker logic incorporates ideas from ByteTrackV2

• Eigen 3.3
• C++ compiler with C++17 or higher support
• CMake 3.14 or higher
• GoogleTest 1.10 or higher (Only tests)

The shared library (libbytetrack.so) can be build with following commands:

mkdir build && cd build
cmake ..
make

Tests have not been fully updated for 3D as the original test data is for 2D tracking.

## Tips

You can use docker container to build the implementation.

```shell
docker build . -t bytetrack-cpp:latest
docker run -ti --rm \
           -v ${PWD}:/usr/src/app \
           -w /usr/src/app \
           bytetrack-cpp:latest
