Embodiment Construction

[0039] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0040] As mentioned above, the existing time warping technology or re-projection technology will cause partial loss of information on the border of the field of view viewed by the user, forming a black border, which prevents the user from being well immersed in the virtual reality environment and affects the user experience. . In view of this phenomenon, the inventor found after in-depth research that if the scene range of the virtual scene...

Abstract

The invention discloses a virtual reality system and a scene presentation method thereof. The system comprises a visual angle determination device for determining a visual angle of a user, a graphics processor for rendering a first virtual scene image which is to be presented to the user and corresponds to a determined first visual angle in response to the determined first visual angle, and performing projection transformation on the first virtual scene image in response to a determined second visual angle so as to obtain a second virtual scene image corresponding to the second visual angle, and a virtual scene presentation device for presenting the second virtual scene image to the user, wherein the scene range of the first virtual scene image is larger than the scene range actually presented by the presentation device to the user. Therefore, the problems of dizziness caused by delay of a visual field and a black boundary caused by the schemes such as a time distortion technology can be solved; and the user can better devote to a virtual reality scene, and the use experience of the user is enhanced.

Description

technical field [0001] The invention relates to the technical field of virtual reality, in particular to a virtual reality system and a scene presentation method thereof. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) is a high-tech that has emerged in recent years, also known as spiritual technology (translated by Qian Xuesen, a famous scientist in my country). Virtual reality is to use computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, so that users can observe things in three-dimensional space in a timely and unlimited manner as if they were there. . [0003] For non-virtual reality applications, such as traditional shooting games, the content display process is as follows: Figure 1A As shown, it includes perspective change 110 , CPU calculation 120 , GPU rendering 130 and screen display 140 . This process usually takes tens to hundreds of mi...
