I’m excited to announce the release of my AprilGrid detection library, a lightweight, cross-platform library for detecting and processing AprilGrids (of Kalibr fame) in images and point clouds.
With this library, you can:
- Detect AprilTags with subpixel accuracy
- Estimate pose and orientation of detected grids
- Draw tag and grid detections
- Generate AprilGrid images
Written in C++ and using OpenCV 4.6.0+, this library is cross platform, can be easily integrated into ROS, and supports tags using any of OpenCV’s four pre-defined April tag dictionaries (16h5, 25h9, 36h10, or 36h11)
Perfect for sensor calibration, robotics, autonomous vehicles, or mapping, the repository is FOSS and is available here. Let me know if you’d like to contribute or if you have questions!
