METHOD FOR GENERATING DEPTH MAPS FOR CONVERTING MOVING 2D IMAGES TO 3D

摘要

METHOD FOR GENERATING DEPTH MAPS FOR CONVERTING MOVING 2D IMAGES TO 3D. A 2D moving image comprises a series of still images known as current frame (K), previous frame (K-1) and so on. The method generates depth maps to convert 2D images to 3D. To do so, the method comprises a first step in which a pyramid of scaled versions of the current frame and the previous frame are generated, a second step in which the optical flow between the current and previous pyramids is calculated, a third step in which the image-point-oriented depth map is calculated, a fourth step in which image segments in the current frame are generated, a fifth step in which a depth map focused on said segments is calculated, obtaining a segment-oriented depth map, and a sixth step in which the segment-oriented maps relating to the current and previous frames are integrated, providing the final map for the current frame.
