Abstract

The invention discloses a near-to-eye display system comprising an image source and an array imaging device. The array imaging device consists of at least two imaging mirror surfaces; and exit pupils corresponding to all the imaging mirror surfaces are spliced together. Image light outputted by the image source is reflected to a human eye by the array imaging device to form a projection image; and ambient light is transmitted by the array imaging device to enter the human eye to form an environmental image. Because the array imaging device consists of at least two imaging mirror surfaces and the exit pupils corresponding to all the imaging mirror surfaces are spliced together, the exit pupil diameter of augmented reality equipment is extended equivalently, so that the image light outputted by the augmented reality equipment can enter the pupil of the eye easily. Compared with the exit pupil of the single optical lens, the exit pupil provide by the system increases obviously, so that the strict restriction of the position of human eye observation is reduced or avoided and thus the applicable people range of the augmented reality equipment is extended. Moreover, pupil distance adjustment of the augmented reality equipment by the user is not required.

Description

technical field [0001] The invention relates to the field of augmented reality, in particular to a near-eye display system. 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 real physical environment images obtained by image acquisition equipment such as cameras, through computer system recognition analysis and query retrieval, virtual images such as text content, image content or image models associated with them are displayed on the real physical environment. In the environment image, users can obtain related extended information such as annotations and descriptions of real objects in the real physical environment, or experience the three-dimensional, highlighted and enhanced visual effects of real objects in the real physical environment. [0003] Existing augmented reality devices ge...
