Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] In this embodiment, the virtual reality device VIVEFocus of HTC is used as the experience client of the virtual reality cloud game.
[0021] refer to figure 1 , a method of reducing image jitter in a virtual reality cloud gaming system of the present invention, comprising the following steps:
[0022] S1, before the user starts browsing, the server first obtains the posture data collected from the client, and then renders the image in the virtual reality game according to the posture data;
[0023] S2, in order to minimize the subsequent time spent on image encoding, the image is directly obtained from the server graphics card.
[0024] S3, encode the acquired image, and encode it into a video stream that is convenient for transmission. In this step, since virtual reality games generally have two screens, for encoding, one encoder c...

The invention discloses a method for reducing picture jitter in a virtual reality cloud game system. The method comprises the following specific steps: S1, acquiring a virtual reality image needing tobe transmitted at a server side; S2, encoding the image into a video stream by adopting a block parallel encoding mode; S3, transmitting the video stream by using a network transmission protocol; S4,receiving the video stream transmitted by the server side at a client side in a buffer area mode; S5, decoding a video frame needing to be displayed into a display image in a parallel decoding mode;S6, completing on-screen display of the image at a display client by using an asynchronous distortion technology; and S7, obtaining a current client posture and predicting the client posture after a period of time. With the method, a problem of picture jittering caused by fluctuation of hardware processing time and fluctuation of network transmission time in a virtual reality cloud game system canbe effectively solved, and the subjective feeling quality of a user in a virtual reality cloud game is improved.
Description
technical field [0001] The present invention relates to the field of cloud games and computer vision, and in particular to a method for reducing picture shake in a virtual reality cloud game system. Background technique [0002] Virtual Reality (Virtual Reality, VR) is a new technology in the computer field developed by integrating computer graphics, man-machine interface technology, network technology, stereoscopic display technology, simulation technology and other science and technology. VR technology can generate a highly realistic virtual environment, which acts on the user's vision, hearing, and touch, immerses the user in it, and interacts with the virtual world to create an immersive experience. Such immersive environments can resemble the real world, creating experiences not possible in ordinary physical reality. Augmented reality systems can be thought of as a form of VR that enables users to view three-dimensional images by feeding virtual information through a l...
