Augmented-reality background black display system

Abstract

The invention discloses an augmented-reality background black display system comprising a light-blocking element for picture information provided by an augmented-reality display device and a semi-transparent element arranged between a display device and the light-blocking element. The light from the display device is reflected by the semi-transparent element, passes through an ocular lens and then enters eyes; reality light passes through an objective lens, is processes by image correction by an image inverting device, and then is focuses on the light-blocking element; and the light focuses at the light-blocking element passes through the semi-transparent element and the ocular lens successively and then enters eyes. According to the invention, the design is novel and the structure is simple. Because of the light-blocking element in a controllable electrification mode, material diversity is formed by the light-blocking element and the imaging product structure types are enriched. On the basis of cooperation of the light-blocking element and the display device, direct imaging on a front black area is carried out and then is superposed on a display device picture. The clear effect without any fuzzy image is realized and the anti-interference capability is high. A problem that the picture content can not be watched clearly because of direct picture penetration due to too bright augmented light can be solved.

Description

technical field [0001] The invention belongs to the field of reality augmentation technology, in particular to a reality augmentation background black display system. Background technique [0002] The goal of augmented reality is to put the virtual world on the screen and interact with the real world. Derived products are emerging products. The existing augmented reality products include Google Glass launched by Google in 2013. Google Glass can be understood as a micro-display after two Group prism processing is equivalent to secondary magnification, the light of the processed picture is focused to infinity, and the human eye accepts the picture in a relaxed state. Google Glass does not have a black pixel display system. The display of black mainly relies on semi-reflective prisms and prism coatings to reduce the passage of light, or use the screen to face darker areas such as black walls, which can improve the display quality of the screen; It is a holographic waveguide di...

Problems solved by technology

The shortcomings of existing augmented reality products are mainly concentrated in the fact that when the images are superimposed on reality, if the background light in reality is too strong, for example, the sunlight is too strong and the images directly penetrate through, making it difficult to see the contents of the images, the images superimposed by the augmented reality will be blurred. Interference, because there is no black light in nature, so reality augmented products cannot project black pixels and display black information. In order to solve reality augmented products, the displayed picture will be affected by background light. Nowadays, there is a lack of a simple structure, low cost, A well-designed reality-enhanced background black display system uses controllable light-blocking materials to directly image a black area in front of the eyes, and then superimposes a reality-enhanced product image on the black area to make the image clear
