Problems solved by technology

However, none of the current head-mounted display devices can meet the requirements of this resolution
If the image resolution of the real scene captured by the camera is increased, the amount of image processing data will be greatly increased, the complexity of image processing will be increased, and the display delay will be increased, and users will be dizzy, etc.

Abstract

the invention discloses an image processing method and a head-mounted display device, and relates to the communication technology field. By providing a high-resolution image for a central area of a user and providing a low-resolution image for the background area, the image definition requirement of the head-mounted display device is met, and the data size of the image can be reduced. The method can be applied to the HMD, the HMD comprises two modules, and each module comprises a camera module, a display screen corresponding to the camera module and a processing module. The camera module comprises a first camera and a second camera, and each module executes the following steps that in response to a detected starting operation, the first camera collects a low-resolution first image, and thesecond camera collects a high-resolution second image; the processing module generates a fourth image according to the first image and the second image, wherein the fourth image comprises a low-resolution image and a high-resolution image; the processing module generates a fifth image according to the fourth image and a third image containing the virtual object, and the display screen displays the fifth image.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to an image processing method and a head-mounted display device. Background technique [0002] Augmented Reality (AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D (Three Dimensional) models. Among them, a typical head-mounted display device (or head-mounted display (HMD)) based on video perspective can capture images of real scenes through cameras, and then compare the captured images with virtual objects. synthesized and displayed on the screen of the head-mounted display device. [0003] When the user wears the head-mounted display device, the screen of the head-mounted display device is very close to the human eyes, and when the human eyes feel the best clarity, the angular resolution of the image can reach 60PPD (Pixels Per Degree). However, none of the current head-mou...
