Three-dimensional video frame rate enhancing method based on depth guide extension block matching

The present invention discloses a three-dimensional video frame rate enhancing method based on depth guide extension block matching. The method comprises a step of carrying out bidirectional movement estimation based on an image block on a video frame, using a movement vector obtained by estimation to compensate to obtain an initial depth insert frame, calculating the two-dimensional structure tensor of each depth image block in the insert frame, and dividing image blocks into edge image blocks and non-edge image blocks according to the two-dimensional structure tensors, a step of dividing the edge image blocks into a plurality of sub blocks, and estimating the movement vector of each sub block by using an extension block matching method based on depth information guide, a step of carrying out adaptive movement compensation on the non-edge image blocks and the edge image blocks with image blocks as a unit and realizing the reconstruction of the insert frame. According to the method, the problem of the insert
