AprilTags serve as visual control point markers in the realms of photogrammetry, robotics, and augmented reality applications. Our detection software can accurately determine both the orientation and identity of each tag in relation to the camera, allowing for precise 3D positioning. The reference design and encoding system utilize an optimized lexicographic encoding method, ensuring robustness against varying lighting conditions and viewing angles. These type 36h11 tags can be effortlessly affixed to a diverse array of surfaces due to their magnetic properties. Unsure of which AprilTag size you need? Refer to our AprilTag test for guidance.
