Abstract

The invention provides a head-mounted display device, which comprises a shell and a group of optical system arranged in the shell. The optical system comprises an image display screen, an optical magnifying lens group and a reflecting and transmitting lens, wherein the image display screen is located above the optical magnifying lens group; and the reflecting and transmitting lens is located below the optical magnifying lens group. The optical path of the optical system is that image optical information emitted by the image display screen is transmitted via the optical magnifying lens group and then reflected to a human eye by the reflecting and transmitting lens; and the environment optical information outside the head-mounted display device is transmitted to the human eye via the reflecting and transmitting lens. According to the head-mounted display device provided by the invention, the structure is simple, wearing is comfortable, and a user can conveniently enjoy the visual experience with the enhanced realistic effect.

Description

technical field [0001] The present invention relates to the field of optical and image display technologies, in particular to a head-mounted display device. Background technique [0002] Augmented Reality (AR for short) is a technology that uses virtual objects or information to enhance the reality of real scenes. Augmented reality technology is usually based on the real physical environment images obtained by image acquisition equipment such as cameras, through computer system recognition analysis and query retrieval, the virtual generated extended information or virtual scene display of associated text content, image content or image models, etc. In the real physical environment image, so that users can obtain related extended information such as annotations and descriptions of real objects in the real physical environment or experience the three-dimensional and highlighted enhanced visual effects of real objects in the real physical environment . Augmented reality techn...
