Problems solved by technology

[0003] The purpose of the present invention is to provide a distance measuring method based on computer vision, an HMD optical system adjustment method and a head-mounted display device using the distance measuring method, so as to solve the problem that the distance between the virtual image of the existing head-mounted display optical system and the human eye cannot be adjusted. Defects, according to the distance from the target image to the human eye, the distance from the virtual image to the human eye can be automatically adjusted, so that the virtual image can be better integrated with the actual environment

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] In recent years, HMD has developed more and more rapidly, and its most anticipated application is augmented reality application. The inventors of the present invention found that in the process of augmented reality, in order to make the virtual information fit seamlessly with the surrounding environment, the existing optical system designed with a fixed imaging distance cannot meet the requirements, and it is necessary to increase the distance between the vir...

Abstract

The invention discloses a distance measurement method based on computer vision, an HMD optical system adjustment method and a head-mounted display device using the distance measurement method. The invention uses image registration technology and optical system imaging principles to calculate the distance between the human eye and the target The distance of the image, that is, the object distance; according to the measured object distance, the imaging distance of the head-mounted display optical system is adjusted to solve the defect that the distance between the virtual image of the existing head-mounted display optical system and the human eye cannot be adjusted. The distance between the virtual image and the human eye can be adjusted automatically, so that the virtual image can be better integrated with the actual environment.

Description

technical field [0001] The present invention relates to the field of wearable computing head-mounted display devices, in particular to a head-mounted display device. Background technique [0002] Existing HMD (Head Mount Display, head-mounted visual device) virtual reality / augmented reality display system, because the optical display system is designed according to a fixed imaging distance, the virtual image displayed in front of the human eye after the image source passes through the optical display system The distance from the human eye is fixed. If such an HMD device is used for augmented reality applications, since the distance between the virtual image and the human eye is constant, and the environment is constantly changing, the virtual image seen through these display systems It is floating in the air, separated from the actual environment, not only can not achieve the real enhanced display effect, but also the user experience is extremely poor. Contents of the inve...
