Registration for stereo vision-based augmented reality using projection technique

Registration is the key problem in AR application systems. In this paper, a simple registration method is proposed using projection technique. It is composed of four procedures: detecting positions of markers and feature points, tracking of features using projection technique, calculation of the model-view matrix, and rendering the virtual objects. In the initial process, four points are specified to build the world coordinate system on which the virtual objects will be superimposed. In the registration process, projection technique is used to track the positions of feature points and calculate the model-view transformation for augmentation. This method can provide accuracy needed for general indoor augmented reality systems and it is performed in. real time.
