Embodiment Construction

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the implementation manners of the present invention will be further described in detail below.

[0028] The embodiment of the present invention proposes a fast coding method for integrated imaging, which judges the depth range of the current CU in advance by referring to the optimal depth information of the corresponding position in the previous frame; at the same time, uses the mode information of adjacent coded PU blocks in the space-time domain, Reduce the list of candidate modes and judge the best prediction mode in advance. The specific implementation steps are as follows:

[0029] 1. Process the integrated imaging data format into YUV format

[0030] The integrated imaging data collected by the camera array are all in PNG format, and the video encoding format required by HEVC is YUV (where Y represents the luminance component, and UV represents the chrominance compon...

Abstract

The invention discloses an integrated imaging rapid coding method. The method comprises the following steps: converting an integrated imaging data format acquired by a camera array into a YUV format;according to the time domain characteristics, limiting the depth range of the current coding block by utilizing the optimal coding depth of the maximum coding block at the corresponding position of the previous frame; when the current CU is encoded, referring to the mode information of the surrounding encoded blocks, reducing the candidate mode list, and reducing the algorithm complexity. Meanwhile, the optimal prediction mode of the RDOQ process is judged in advance by utilizing the spatial correlation of the integrated imaging three-dimensional data.

Description

technical field [0001] The invention relates to the field of integrated imaging coding, in particular to a fast coding method for integrated imaging. Background technique [0002] As one of the true 3D display technologies, integrated imaging has received extensive attention in recent years and has become a current research hotspot. Since the integrated imaging display does not require other equipment to assist, and the viewpoint is continuous, it has smooth motion parallax, etc., and has more advantages than traditional 3D display technology. However, the amount of information in integrated imaging stereoscopic element images is much larger than that of ordinary 2D images. In order to meet the requirements of integrated imaging 3D data storage and transmission, it needs to be effectively compressed. Considering the correlation of integrated imaging data in both horizontal and vertical directions, the MV-HEVC (Multiview High Efficiency Video Coding, Multiview High Efficienc...
