A kind of VR panoramic video information processing method

Abstract

The present application belongs to the technical field of panoramic video data processing methods, and in particular relates to a VR panoramic video information processing method. Including the step of optimizing video intra-frame coding, the step of optimizing video intra-frame coding includes a coding unit processing process; the coding unit processing process includes the following steps: S1, divide the image coding area based on the coding tree unit threshold value; S2, Establishing pruning decision sample attributes in different regions based on the rate-distortion optimization value; S3. Pre-division decision sample attributes based on pruning decision sample attributes; S4. Establishing a pruning decision tree of coding units with a size of 64*64 in the edge area; By improving the steps of recursive partitioning in the application, it is possible to quickly perform the associative decision attribute of regional partitioning based on the coded unit, effectively improve the intra-frame prediction efficiency of the HEVC quadtree coding method, and improve its accuracy, which is useful for improving panoramic video. The coding and coding efficiency is improved, and the local distortion deformation is avoided at the same time.

Problems solved by technology

For virtual reality technology, panoramic video and image processing and use technology are the core elements that affect its actual application effect, cost, and effectiveness. Although the development of panoramic video has a long history, in some early photography equipment and film and television works , can see the application scene of panoramic video or image, but it is mainly used in various themes or the occasions where most objects are static objects or backgrounds. For occasions with a large number of dynamic elements such as competition scenes, due to the large amount of data, There are many sampling points in the image and video, resulting in distortion and deformation of the pixels of the panoramic video in different areas after mapping, which not only makes the video more complicated and difficult in the data processing process, but also leads to more serious distortion and deformation after reanalysis. Seriously affect the final quality of images and videos
