Abstract :
This paper proposed the key technologies of the augmented reality (AR) system with image acquisition system and head-mounted displays are separately. The first stage is to detect features between two images using SIFT algorithm. A keypoint descriptor with 128 dimensional element features is created by first computing locations, scales and orientations of keypoint. Features are matched based on nearest neighbor method in order to identify overlap region. Image is blended by wavelet transform. Final, virtual object is added into the partial image of panoramic that agree with viewer´ sight. Experimental results show that the effect of local augmented display was perfect.
