Problems solved by technology

[0003] At present, there are some deficiencies in the control methods of virtual reality objects and application scenarios in the virtual reality scene, which slows down the processing speed of the virtual reality server. The object cannot be adapted to the application scene, and the application scene environment is usually fixed, which seriously affects the user experience

Embodiment 1

[0024] A low-latency control method convenient for virtual reality object control, the method comprising the steps of:

[0025] (1) Image acquisition and display: When a virtual reality display request is received, the corresponding virtual reality configuration file is obtained from the virtual reality server, and the video information of the virtual reality scene is obtained, and the video frames that make up the virtual reality scene video are obtained, N≥ 2. Then, the acquired video frames are encoded, transmitted and decoded through the codec algorithm, and finally the display unit presents the decompressed image slices to the user. The video signal frame rate corresponding to the image frames is 30FPS, and the display unit refreshes at 60Hz rate output, which can avoid the flickering and incoherence of the virtual reality scene caused by too low refresh rate, so as to improve the image display effect and visual perception. The codec algorithm is H.261 or H.263 or H.264 or...

Embodiment 2

[0031] A low-latency control method convenient for virtual reality object control, the method comprising the steps of:

[0032] (1) Image acquisition and display: When a virtual reality display request is received, the corresponding virtual reality configuration file is obtained from the virtual reality server, and the video information of the virtual reality scene is obtained, and the video frames that make up the virtual reality scene video are obtained, N≥ 2. Then the obtained video frames are encoded, transmitted and decoded through the codec algorithm, and finally the display unit presents the decompressed image slices to the user. The video signal frame rate corresponding to the image frames is 50FPS, and the display unit refreshes at 80Hz rate output, which can avoid the flickering and incoherence of the virtual reality scene caused by too low refresh rate, so as to improve the image display effect and visual perception. The codec algorithm is H.261 or H.263 or H.264 or ...

Embodiment 3

[0038] A low-latency control method convenient for virtual reality object control, the method comprising the steps of:

[0039] (1) Image acquisition and display: When a virtual reality display request is received, the corresponding virtual reality configuration file is obtained from the virtual reality server, and the video information of the virtual reality scene is obtained, and the video frames that make up the virtual reality scene video are obtained, N≥ 2. Then, the acquired video frames are encoded, transmitted and decoded through the codec algorithm, and finally the display unit presents the decompressed image slices to the user. The video signal frame rate corresponding to the image frames is 60FPS, and the display unit refreshes at 100Hz rate output, which can avoid the flickering and incoherence of the virtual reality scene caused by too low refresh rate, so as to improve the image display effect and visual perception. The codec algorithm is H.261 or H.263 or H.264 o...

Abstract

The invention discloses a low-latency control method convenient for virtual reality object control, and the method comprises the following steps: obtaining a corresponding virtual reality configuration file from a virtual reality server when a virtual reality display request is received, obtaining virtual reality scene video information, obtaining video frames forming a virtual reality scene video, wherein N is greater than or equal to 2, and then encoding, transmitting and decoding the obtained video frame through an encoding and decoding algorithm. The method has the advantages that the virtual reality object is convenient to control, the refreshing frequency of the virtual reality scene is improved, the control delay of the virtual reality object can be effectively reduced, and the problems that the processing speed of a virtual reality server becomes slow due to an existing control mode, meanwhile, the response of virtual reality interaction is too slow due to too large transmission delay, and therefore, the problem that the virtual reality object cannot be matched with the application scene is solved, and the user experience of virtual reality can be improved.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a low-latency control method for controlling virtual reality objects. Background technique [0002] Virtual reality technology (VR) is a computer simulation system that can create and experience virtual worlds. It uses computers to generate a simulated environment and immerses users in the environment. Virtual reality technology is to use the data in real life, through the electronic signal generated by computer technology, combine it with various output devices to transform it into a phenomenon that people can feel. These phenomena can be real objects in reality. , it can also be a substance invisible to our naked eyes, which is represented by a three-dimensional model. Virtual reality has all the perception functions that human beings have, such as hearing, vision, touch, taste, smell and other perception systems. Finally, it has a super simulation system, which truly ...
