Method and apparatus for optimizing motion image in virtual reality scene

Abstract

The invention discloses a method and an apparatus for optimizing a motion image in a virtual reality scene. The method comprises the steps that: a rendering thread renders contents to be displayed frame by frame, is in a rendering state in the rendering process, and enters a waiting state every after rendering one frame; a send-to-screen thread reads a newest rendering result frame by frame according to the same frequency with a screen refresh rate; the send-to-screen thread, according to a reading result, judges a state of the rendering thread, when judging that the rendering process is in the waiting state, sends the reading result to a screen for display after processing the reading result and awakens the rendering thread, and when judging that the rendering process is in the rendering state, executes a one-time screen clearing operation; and after being awakened, the rendering thread carries out rendering on a next frame of contents. According to the technical scheme disclosed by the invention, by asynchronously refreshing the rendering thread and the send-to-screen thread, the problems of reduction of system performance and low rendering frequency which are brought in when a screen refreshing rate is improved are effectively solved, so that an afterglow effect is effectively reduced, and the problem of image blurring under the motion condition is improved.

Description

technical field [0001] The invention relates to the technical field of image rendering, in particular to a method and device for optimizing moving images in a virtual reality scene. Background technique [0002] With the popularity of VR (virtual reality) in recent years, many domestic manufacturers have gradually entered this market, especially the mobile VR market. When we wear the headsets of foreign manufacturers, the experience is very good and the feeling is very good. But when we wear the domestic VR headsets, it is fine when it is not moving, but the image will be blurred when it moves, making people extremely dizzy. [0003] The main cause of vertigo is a mismatch between head movement and visually observed head movement. This is also the part where VR headsets can be technically improved. There are two parts to this point: inter-frame delay and intra-frame delay. Intra-frame delay is the main cause of image blur. Such as figure 1 As shown, we can see that the ...

Problems solved by technology

However, the screen refresh rate of the current mobile platform can only reach 120Hz, and the performance of other hardware devices cannot match the performance of other hardware devices, which makes the system performance drop rapidly, and the rendering frequency of the application is far from being stable at a higher frequency. It will cause the content of the same frame to be repeatedly refreshed when refreshing the frequency to form the same afterglow effect as the 60Hz screen
