An efficient augmented reality method for sports scene visualization from single moving camera

摘要

An algorithm to insert augmented reality in sports scenes is presented. The goal is to augment an image to the scene so that it appears as a part of the original scene. The proposed algorithm uses the homography relationship between the image coordinates and the world coordinates, then utilizes the Sift algorithm to find the corresponding points between two frames. By using the homography map we can detect the interested insertion region in each frame. To insert the virtual content, the algorithm segments the foreground and then uses the inverse homography map to insert the augmented reality in the original frame. The proposed algorithm is robust against camera movements. As shown in experimental results, the augmented image is well placed in the desired location. The experimental results show the strengths of the proposed method.
