Problems solved by technology

[0003] However, when a user wears a VR display device to watch virtual reality content, the screen viewing angle provided by the VR display device may not be consistent with the user's expected viewing angle, thereby affecting the user experience.
For example, when the user's head is upright and the user is facing forward horizontally, the VR display device may display image content with a non-horizontal viewing angle due to positioning errors or other related factors
Or, when the user intends to use the VR display device in a lying position, the VR display device will not immediately display the picture corresponding to the horizontal viewing angle, and the user often needs to perform additional calibration steps to adjust the display picture

Abstract

The invention provides a visual angle correction method, a virtual reality display system and an arithmetic device. Whether a head-mounted display device is worn on the head of a user or not is detected through a wearing sensor. In response to the fact that the head-mounted display device is worn on the head of a user, a current video picture displayed by the head-mounted display device is obtained, and the current video picture is generated based on azimuth angle positioning parameters of the head-mounted display device. The picture pitch angle of the current video picture is judged. The azimuth angle positioning parameter of the head-mounted display device is corrected according to the picture pitch angle, so that the head-mounted display device displays a next video picture generated based on the corrected azimuth angle positioning parameter.

Description

technical field [0001] The invention relates to a virtual reality technology, in particular to a viewing angle correction method, a virtual reality display system and a computing device. Background technique [0002] In recent years, virtual reality (virtual reality, VR) display technology has developed rapidly. The VR display device uses computer simulation to generate a three-dimensional virtual world, providing users with a simulation of visual senses, making users feel as if they are actually there. In general, a VR display device may be implemented as a head mounted display device (HMD). The VR display device can allow users to observe things in three-dimensional space in time and without limitation. When the user moves, the computer can immediately perform complex calculations, and send the accurate three-dimensional world image back to the VR display device, so that the user can feel the sense of presence. [0003] However, when a user wears a VR display device to ...
