Coming soon…
We are introducing an open-source, monocular optical tracker system for animal research that consists of a small size, compact, and lightweight visual marker and software capable of tracking the target real-time, at high framerate on camera images. Our solution improves upon the state of the art by providing accurate 3D pose (position and orientation) at a wider range of orientations than other tracking systems. Performance evaluations using synthetic tests and laboratory rats demonstrated high accuracy and robustness. The system uses a single camera and the 3D printable target to keep implementation requirements and costs reasonable.
The open-source software package includes:
- Tracking software
- Camera calibration software
- 3D printable CAD drawings of visual target
- Assembly and setup instructions
- Tools for registering camera to other coordinate frames
- Documentation
System requirements:
- Computer with Intel Core i7 CPU or better
- Camera with LED ring light
- Linux Ubuntu 18.04+ operating system & ROS (Robot Operating System)
