AprilTags Visual Fiducial System
AprilTag is a visual fiducial system, useful for a wide variety of tasks
including augmented reality, robotics, and camera calibration. 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. The AprilTag library is implemented in C with no external dependencies.
It is designed to be easily included in other applications, as well as be
portable to embedded devices. Real-time performance can be achieved even on
cell-phone grade processors.
