Near-to-eye display system and augmented reality device

Abstract

The invention discloses a near-to-eye display system and an augmented reality device. The near-to-eye display system includes a scanning light source, a focal length lens group, a reflective and permeable plane mirror and a reflective and permeable concave mirror; scanning light outputted by the scanning light source passes through the focal length lens group, and then is reflected to the reflective and permeable concave mirror through the reflective and permeable plane mirror; the light is converged and reflected by the reflective and permeable concave mirror, and then passes through the reflective and permeable plane mirror, and thereafter is received by the eyes of a person; and external ambient light passes through the reflective and permeable plane mirror and the reflective and permeable concave mirror, and then is received by the eyes of the person. According to the near-to-eye display system provided by the embodiments of the invention, the traditional optical devices are adopted to transmit the scanning light and the external ambient light to the eyes of the person, and therefore, the accuracy of the color of a virtual image provided by the near-to-eye optical system can be ensured, and the uniformity of the brightness of the virtual image can be also ensured.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a near-eye display system and augmented reality equipment. Background technique [0002] Augmented reality (English: Augmented Reality; abbreviation: AR) 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 environ...
