Head-mounted display device and display method thereof

Abstract

The invention provides a head-mounted display device and a display method thereof. The device comprises a carrying device, a first optical module and a second optical module, the first optical module is located in front of a display device carried by the carrying device and forms a certain angle with the display device, the second optical module is located below the display device and forms a certain angle with the display device; the carrying device is used for carrying the display device; the first optical module is used for reflecting the image displayed by the displayed device to the second optical module; the second optical module is used for reflecting the image of the first optical module to a preset position to form a first image, and transmits the images of real objects outside the head-mounted display device to a preset position to form a second image, the second image is superimposed with the first image. The reality augmentation device composed of the display device, the first optical module and the second optical module is larger in view field, and simple in optical system.

Description

technical field [0001] The present invention relates to the field of wearable technology, in particular to a head-mounted display device and a display method thereof. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a technology that integrates real world and virtual world information. It can calculate the position and angle of camera images in real time and add corresponding images. The interaction between the virtual world and the real world has become one of the research hotspots of many well-known universities and research institutions at home and abroad in recent years because of its wide application fields. [0003] Current augmented reality devices usually use smaller display screens. In order to achieve the same exit pupil size, the design difficulty of the optical system is greatly increased. Therefore, the performance of the current augmented reality devices is poor, or the optical system is very complicated. Contents of the invention ...
