Problems solved by technology

In the prior art, it is possible to reduce the transmission bandwidth by limiting the user's viewing angle and using a sudden stimulating image or sound to attract the user's viewing angle to the characteristic area of ​​the image spherical surface, but there is still a lack of a virtual reality that guarantees the main viewing angle (FOV). Reliable method and device for reducing transmission bandwidth while maintaining video quality

Abstract

The embodiments of the invention relate to a method for projecting virtual reality panoramic video stream to a user, comprising the steps of dividing the panoramic video stream into multiple spherical subareas, providing different video qualities for the spherical subareas related to a user perspective and the spherical subareas unrelated to the user perspective according to user perspective information tracked in real time, and moving user observation points, thus realizing an optimal video reproduction effect and reducing the transmission bandwidth. The invention further relates to equipment for projecting virtual reality panoramic video stream to a user.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, and more particularly relates to a virtual reality panoramic video stream projection method and device. Background technique [0002] Virtual reality (Virtual Reality, VR) is a technology that has been applied in video, photography, cinema and game scenes. It includes the cross combination of multimedia, human-computer interaction, sensor, network technology and other technologies. Virtual reality can create a subjectively perceivable and freely observable virtual world based on the user's vision, hearing and even touch, bringing users a high sense of immersion and participation. It is an important development direction in the field of multimedia and online entertainment in the future. Virtual reality technology generally includes two parts: related hardware and software. Virtual reality hardware includes, for example, body trackers and sensors, user input devices, 3D displays, p...
