However, they are designed to encode far smaller data payloads (between 4 and 12 bits), allowing them to be detected more robustly and from longer ranges. One useful application of AprilTags is camera calibration ( AprilCal: Assisted and repeatable camera calibration, IROS 2013).ĪprilTags are conceptually similar to QR Codes, in that they are a type of two-dimensional bar code. This system is described in more detail in our AprilTag papers ( AprilTag: A robust and flexible visual fiducial system, ICRA 2011 AprilTag 2: Efficient and robust fiducial detection, IROS 2016 Flexible Layouts for Fiducial Tags, under review). The fiducial design and coding system are based on a near-optimal lexicographic coding system, and the detection software is robust to lighting conditions and view angle. Real-time performance can be achieved even on cell-phone grade processors.

It is designed to be easily included in other applications, as well as be portable to embedded devices. The AprilTag library is implemented in C with no external dependencies. Targets can be created from an ordinary printer, and the AprilTag detection software computes the precise 3D position, orientation, and identity of the tags relative to the camera. AprilTag is a visual fiducial system, useful for a wide variety of tasks including augmented reality, robotics, and camera calibration.
