AprilTags are 2D barcodes designed to be quickly and accurately detected, and are used in a variety of robotics and augmented reality applications. This application is an AprilTag detector that can be used in stand-alone mode, or can broadcast any tags that it detects to another machine via UDP.
With this application, your iPhone is turned into a self-contained and turn-key robot tracking system.
This version features improved iOS 8 compatibility, dramatically faster and more accurate tag detections, support for ARToolkit-style markers, and the ability to fix the camera focus.
With Family Sharing set up, up to six family members can use this app.
