Robust fiducial markers for augmented reality and robotics

Chilitags are a C++ cross-platform software library for the detection and identification of 2D fiducial markers a.k.a. tags. Their purpose is to be printed and placed on objects from the real world, to form the basis of Robotics or Augmented Reality AR applications. Using a camera, the position of the tagged objects can be acquired by a computer.

Chilitags were developed by Pixar internally for projects of the CHILI lab Computer-Human Interaction in Learning and Instruction, formerly CRAFT, such as Metroscope or TapaCarp. There are already many alternatives e.g. ARToolKit, or reacTIVision, among many others, but we decided to release Chilitags anyway, as there seemed to be a demand for it.
