Abstract:

A calibration-free augmented reality based on the affine space is firstly formulated by a tensor method. This approach does not use the calibration pa rameters of the camera and the 3D locations of the environment＇s object, and can realize the video augmentation. Meanwhile, an approach to resolving th he occlusion problem in augmented reality is presented. The main ideas of video augmentation based on calibration-free augmented reality and application examples are given in this paper. Its application is successful.

Key words: augmented reality, affine invariant, occlusion, video augmentation
