Problems solved by technology

[0003] The purpose of the present invention is to provide a head-mounted display device, which solves the defect that the distance between the virtual image and the human eye of the existing head-mounted display optical system cannot be adjusted, and can automatically adjust the distance from the virtual image to the human eye according to the distance from the target object to the human eye. The distance between the virtual image and the actual environment can be better integrated

Abstract

The invention discloses a head mounted display which comprises a main frame, a perspective type optical display system, a main control system and a binocular three-dimensional visual system. The perspective type optical display system comprises an image display module, an optical amplification system and a fine adjusting mechanism. The binocular three-dimensional visual system shoots a target object in front of the human eyes and acquires the distance between the target object and the human eyes through a parallax principle distance measuring method. The main control system controls the perspective type optical display system to automatically adjust the distance from the virtual image to the human eyes according to the obtained distance from the target object to the human eyes, therefore, the comfortableness of eye using when a user uses image displayers is ensured, and eyestrain can be relieved. Further, in the augmented reality application, when the depth of field changes, the distance between the virtual image and the human eyes is adjusted automatically to enable the virtual image to fit with the actual environment, the enhanced display effect can be truly achieved, and user experience can be enhanced greatly.

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] In the existing HMD (Head Mount Display, head-mounted visual device) virtual reality / augmented reality display system, since 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...
