AprilTags serve as essential visual control point markers in various fields, including photogrammetry, robotics, and augmented reality. With specialized detection software, AprilTags can accurately determine both the orientation and identity of the tag in relation to the camera, allowing for precise 3D positioning. The reference design and encoding system utilize an optimized lexicographic encoding approach, ensuring reliability across diverse lighting conditions and viewing angles. Our 36h11 tags feature a magnetic backing, enabling effortless attachment to a wide variety of surfaces. Unsure about the right size of AprilTag for your needs?
