Matrix: a realtime object identification and registration method for augmented reality

The paper introduces a novel technique for producing augmented reality systems that simultaneously identify real world objects and estimate their coordinate systems. This method utilizes a 2D matrix marker, a square shaped barcode, which can identify a large number of objects. It also acts as a landmark to register information on real world images. As a result, it costs virtually nothing to produce and attach codes to various kinds of real world objects, because the matrix code is printable. We have developed an augmented reality system based on this method, and demonstrated several potential applications.
