Abstract: With the advent of the 5G era, the application of panoramic VR technology shows explosive growth. In order to solve the deficiency of existing panoramic mosaic software, an improved image stitching algorithm is proposed, which combines SIFT, improved RANSAC and multi-dimensional index tree. The experimental results show that the image stitching algorithm has satisfying image definition, anti-noise capacity and practicability.
Keywords: panoramic mosaic technology; SIFT algorithm; RANSAC algorithm; homography matrix; KDG-tree
全景圖是VR中一種實(shí)際場(chǎng)景表示方法,通常要獲得高質(zhì)量的全景圖需要購(gòu)買昂貴的專用拍攝設(shè)備,并且設(shè)備需要專業(yè)人員精確地校準(zhǔn),因此獲取全景圖成本高。(剩余4603字)
