AprilTags are a powerful tool for computer vision applications in robotics, augmented reality, and camera calibration. Developed by researchers at the University of Michigan, these visual markers are designed to be easy to detect and track, even in challenging lighting and environmental conditions. With their unique pattern of black and white pixels, AprilTags can be used to determine the position and orientation of a marker in 3D space, making them ideal for localization, mapping, and navigation in robotics. They can also be used in augmented reality applications to overlay virtual objects onto the real world, or for camera calibration (as a fiduciary marker) to determine the intrinsic and extrinsic parameters of a camera. At Sky High Bull's-Eye, we offer AprilTags as either a sticker or a magnet to provide multiple options for using AprilTags in the field. This set of AprilTags are the 3”x3” magnetic version, great for adding an AprilTag to metal objects that are in close proximity or for training purposes. Our AprilTags are made from high-quality materials and are built to withstand the harshest outdoor conditions, ensuring they will last you for years to come. We created the AprilTags exactly to the scale that the original creator intended, keeping the white border present, which helps with the identification of the targets. If you're looking for a reliable and accurate solution for your computer vision needs, AprilTags are the perfect tool for you.
