Problems solved by technology

[0004] The development of depth map generation technology based on binocular stereo vision has made it possible to quickly generate high-quality depth maps, but because the existing technology does not consider temporal correlation, when operating on image sequences, each depth The maps are generated independently, which leads to severe background and edge jitter in the generated depth map sequence during continuous playback, which affects the overall presentation effect

Abstract

The invention discloses a method and a device for eliminating the background and edge shake of a depth map sequence. The method comprises the following steps: reading the background image of a source image sequence and calculating to obtain the depth map of the background image; calculating the frame difference between the source image sequence and the background image to obtain a frame difference array; calculating to obtain the depth map of each frame of the source image sequence; judging the foreground and the background of the depth map of a source image according to a preset threshold value and eliminating background shake; assigning a value to the foreground of the depth map of the source image to eliminate foreground profile shake; and optimizing through median filtering and bilateral filtering to obtain the final depth map of the source image. By adopting the method for eliminating the background and edge shake of the depth map sequence, the invention has the advantages that the defects of the prior art are overcome, the image shake is effectively eliminated, the interference noise is eliminated and the edge is smoothened.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a method for eliminating background and edge jitter of a depth map sequence. Background technique [0002] Three-dimensional images and displays are an important form of expression for future information systems. On the one hand, three-dimensional images and displays have distinct layers and bright colors, and have a strong visual impact, allowing viewers to stay longer and leave a deep impression on them; In addition, the three-dimensional images and displays give people a real and lifelike character, and the characters are ready to appear, and there is an immersive feeling, which has a high artistic appreciation value. Just because three-dimensional images and videos have the characteristics that these plane images and videos do not have, they have broad application prospects in fields such as computer display, television, video, robotics, measurement, inspection, medic...
