Video image obtaining method and apparatus

Abstract

The invention provides a video image obtaining method. The method comprises the following steps: obtaining a main viewing direction of a user; determining an area display priority of each viewing area according to the main viewing direction of the user; determining display resolution of each viewing area according to the area display priority of the viewing area; and obtaining corresponding video images of each viewing area according to the display resolution of the viewing area. The invention further provides a video image obtaining apparatus. According to the video image obtaining method and apparatus provided by the invention, the display resolution of each viewing area is set according to the main viewing direction of the user, thereby effectively reducing the video processing ability requirements of a corresponding video player and the corresponding network environment requirements, and thus the making cost of the corresponding video player is reduced.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video image acquisition method and acquisition device. Background technique [0002] With the development of virtual reality (Virtual Reality) and augmented reality (Augmented Reality) technology, various virtual reality applications have been developed, such as 3D panoramic video playback, 3D panoramic game experience, and 3D panoramic screen live broadcasting. [0003] However, the existing 3D panoramic films not only need to record partial images of multiple display areas, splicing the partial images of multiple display areas, etc., but also need to simultaneously record multiple display areas Partial images of the image are played simultaneously. If the user is watching an ultra-high-definition online movie, multiple partial high-definition video images need to be transmitted at the same time, which requires high network transmission. After multiple parti...
