Abstract

The invention discloses a three-dimensional method for plane videos based on feedback control. The three-dimensional method comprises the following steps of: reading in key frames in a plane video frame sequence, and obtaining foreground objects of the key frames by an image segmentation algorithm according to inputted manual marks of the key frames; and generating a marking line of the foreground objects of the key frames in a closed loop feedback control mode, expanding the marking line to non-key frames frame by frame, recovering the foreground object of each non-key frame by the image segmentation algorithm, carrying out unified depth assignment on the foreground objects of the key frames and the non-key frames so as to obtain depth map sequences of the plane video frame sequence, and carrying out two-direction depth synthesis on the depth map sequences so as to a final depth map sequence. According to the method disclosed by the embodiment of the invention, only a few key frames are subjected to man-machine interaction operation, and the closed loop feedback control mode is adopted, thereby improving the efficiency and guaranteeing the accuracy of the depth map.

Description

technical field [0001] The invention relates to the field of computer image processing, in particular to a feedback control-based three-dimensional method for plane video. Background technique [0002] As an important form of expression of current film and television works, stereoscopic video has clear layers, bright colors and strong visual impact. With the global success of stereoscopic film and television works in recent years, stereoscopic video is displayed on terminals, Robot navigation, aerospace, military training, medical education, game media and other fields have broad market prospects and commercial value, and are widely considered to be the main direction of the future development of the film and television industry. [0003] Compared with the original planar video production, the production of stereoscopic video needs to be able to present layered scene depth information, so that the film and television works have a strong visual impact and give people an immer...
