Embodiment 1

[0036] Such as figure 1 As shown, this embodiment provides a method for rendering multiple video streams in virtual reality based on load balancing, including the following steps:

[0037] Step S1: GPU initialization, divided into two grids according to functional blocks, Grid0 and Grid1, Grid0 is used for video stream rendering, Grid1 is used for video compression processing, and each grid has multiple thread blocks for processing.

[0038] Step S2: Receive multiple video streams that need to be rendered, and obtain GPU performance parameters;

[0039] In the step S2 in this embodiment, the GPU performance parameters include the size of each thread block, the number of thread blocks in the Grid0 and the number of thread blocks in the Grid1, and the thread blocks in the Grid0 Same as the thread block quantity and size in the Grid1, in order to prevent the video stream from processing a larger task conflict, if in the step S2, the total number of multiple video streams receive...

Abstract

The invention discloses a virtual reality multi-video stream rendering method based on load balancing, relates to the technical field of multi-channel video rendering, and solves the problem of resource waste when multi-channel videos are rendered. The method comprises the following steps: initializing a GPU, and dividing the GPU into two grids Grid0 and Grid1 according to function blocks, wherein the Grid0 is used for video stream rendering, the Grid1 is used for video compression processing, and a plurality of thread blocks for processing are arranged in each grid; receiving a plurality of video streams needing to be rendered, and obtaining GPU performance parameters; allocating a thread block for processing for each video stream based on load balancing; transmitting each video stream to the allocated thread block for processing; and after processing is finished, transmitting a processing result. The method has the advantages of high treatment efficiency and full utilization of resources.

Description

technical field [0001] The present invention relates to the technical field of multi-channel video rendering, and more specifically relates to the technical field of load balancing-based virtual reality multiple video stream rendering methods. Background technique [0002] The 21st century is the information age, and the rapid development of information science and information industry promotes the expansion of traditional optical instrument science to optoelectronic information science. The development of modern optoelectronic information and its industry requires that the new generation of scientific researchers and engineers not only have a solid theoretical foundation, but also have the ability to apply the theory they have learned to model and simulate to solve various problems in optoelectronic information and modern optics. Ability to become a high-level talent with new knowledge structure and strong innovation ability. [0003] Optical simulation is one of the key t...
