Dynamic time frame compensation rendering system and dynamic time frame compensation rendering method for virtual-reality mobile terminal

Abstract

The invention discloses a dynamic time frame compensation rendering system and a dynamic time frame compensation rendering method for a virtual-reality mobile terminal. The method comprises the following steps of generating an application frame buffer sequence by use of frame rendering, extracting the up-to-date or latest application frame from the application frame buffer sequence, and performing secondary rendering, thereby obtaining a time frame; sending the time frame to a shared buffer; and under sequence control of a vertical synchronous management module, reading a time frame rendering result by use of a screen, and performing updating. By virtue of the design of the shared buffer, a GPU rendering result is directly stored in a cache updated by the screen, so that delay of multi-caching exchange is reduced; by virtue of vertical synchronous time management, the GPU rendering time is controlled, collision between GPU rendering writing and screen update reading is avoided, frames can be normally displayed with low delay, and no splitting is generated.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a dynamic time frame compensation rendering method of a virtual reality mobile terminal. Background technique [0002] Virtual reality technology comprehensively utilizes computer graphics, photoelectric imaging technology, sensing technology, computer simulation, artificial intelligence and other technologies, and with the help of various interactive devices, it aims to provide users with a realistic and multi-sensory virtual world. [0003] In recent years, virtual reality technology has developed rapidly, and host-side virtual reality uses high-performance PCs or game consoles as the computing core to provide virtual reality experience. With its powerful hardware, it has been able to bring users a very good immersive experience, but due to its high cost and cumbersome supporting equipment, it has not been widely popularized. In contrast, the threshold for mobile virtual reality...

[0007] On the other hand, the GPU performance of mobile virtual reality is limited. Compared with mobile phones or tablets, which are mostly 2D screens and scenes with low update frequency, each frame in virtual reality scene rendering needs left and right eyes to render, and each frame Therefore, the GPU will run at high load for a long time, resulting in high power consumption. The mobile virtual reality is mainly powered by batteries, and high power consumption will cause heat dissipation and persistence problems, which will directly affect the user experience.
