Embodiment Construction

[0069] The structural diagram of the expression method for the 3D scene is as follows: figure 1 .

[0070] Blocks 101 to 105 in the figure respectively represent an operation, wherein: 101 is to segment the image of the middle viewpoint, and the segmentation operation divides several objects: object 1, object 2, ..., object n; 102 It is to add the occlusion information to the corresponding object. If no occlusion information is added, the object i 1 (i 1 = 1 1 ,2 1 ,...,n 1 ) is the same as its input, if the occlusion information is added, the object j 1 (j 1 = 1 1 ,2 1 ,...,n 1 ) includes the data of the object j and the data of the occlusion information when input; 103 is to obtain the depth function corresponding to each object or object in the object, and 104 is to obtain the depth level and depth change corresponding to each object or object in the object mode, 105 is a control selection switch, if you choose to use the depth function to express the depth inform...

Abstract

The invention discloses a method for expressing three-dimensional scenes. The method comprises the following steps: firstly, according to input multipath video image sequences and information extracted from each video image sequence, identifying and extracting the semanteme and the edge of an object in an actual scene and acquiring the depth information of the three-dimensional scene, and segmenting a video image at a middle view point on the basis of the depth information; adding block information extracted from video images of other view points in the blocked position of a blocked object according to the block relation between the segmented objects; and finally, according to the extracted depth information, expressing the depth of each object by a depth function or by both depth level and depth change mode. The invention also discloses a television system for processing input multipath video image data by the method.

Description

technical field [0001] The invention relates to the field of video image processing, in particular to a method for expressing a three-dimensional scene and a television system. Background technique [0002] With the continuous improvement of people's requirements for audio-visual enjoyment, since the first TV came out, TV technology has achieved rapid development in less than a century, from black and white TV to color TV, from analog TV to digital TV, from standard definition From TV to high-definition TV, more and more advanced display technologies are constantly impacting people's senses. Driven by the wave of science and technology, the next generation of TV technology, free viewpoint TV, and TV technology with more visual impact - 3D TV is quietly coming to people. [0003] Whether it is a free-viewpoint TV or a 3D TV, it is necessary to obtain multi-viewpoint video images of a 3D scene. There are usually two ways to obtain multi-viewpoint video images, one is to use ...
