Image processing method, head-mounted display (HMD) and rendering equipment

Abstract

The embodiment of the invention discloses an image processing method, a head-mounted display (HMD) and rendering equipment. The method comprises the following steps: sending the gesture information of the HMD at the first moment to the rendering equipment; receiving the video data from the rendering equipment, wherein the video data contains the image data that is rendered according to the gesture information; obtaining the gesture information of the HMD at the second moment, wherein the second moment is later than the first moment; and adjusting an image indicated by the image data according to the information difference between the gesture information at the second moment and the gesture information at the first moment to obtain an adjusted image for display. By adopting the image processing method, the HMD and the rendering equipment disclosed by the embodiment of the invention, the rendering image data obtained by the rendering equipment based on the gesture information at the first moment is adjusted by the HMD, and the gesture information at the second moment for adjustment processing does not need to be sent to the rendering equipment so as to ensure that the adjusted image data can be matched with the head rotation, and the picture drawing delay caused by the scene changes due to the head rotation can be eliminated.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an image processing method, a head-mounted display and a rendering device. Background technique [0002] Virtual reality (Virtual Reality, VR) technology is an emerging multimedia technology in recent years. It is a computer simulation system that can create and experience virtual worlds. In a VR scene, after a user wears a head-mounted display (Head Mounted Display, HMD) integrating a graphics system, an optical system, and an attitude tracking system, the user can obtain an interactive immersive experience. [0003] In VR video transmission scenarios, wireless transmission is often used. Currently, the wireless VR video transmission process is as follows: figure 1 As shown, the HMD collects the attitude information and transmits it wirelessly to the rendering device (Application Processor, AP), and the AP renders the corresponding image data / video data according to...

Problems solved by technology

[0004] However, due to the second rendering, it is necessary to shift according to the information difference between the attitude information corresponding to the frame image and the attitude information collected by the HMD at the current moment to match the head rotation, that is to say, the attitude information collected at the current moment needs to be transmitted wirelessly. To the AP side, there is a transmission delay in the transmission process of the attitude information, so that the adjusted image still cannot match the head rotation, so the screen drawing delay caused by the scene change caused by the head rotation cannot be eliminated
