Abstract

The invention discloses DLP technology AR glasses based on RGB laser light. The emergent end of a laser light source is connected with the incident end of a dodging device; the emergent end of the dodging device is connected with the incident end of a spatial light modulator; and an imaging lens is connected with the emergent end of the spatial light modulator for imaging. According to the DLP technology AR glasses based on the RGB laser light, the laser light is used as the light source; good directivity of the laser light is utilized; the laser light source as a display light source has a wider color gamut, and can display more colors, so that real objects can be more really restored, virtual images in augmented reality are more vivid, and better experience is brought to users; and meanwhile, the service life of the laser light source reach a length of 20,000 hours, which is far higher than 1,000 hours of a common light source, so that the number of times of replacing the light source is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of laser display and augmented reality, in particular to a kind of RGB laser-based DLP technology AR glasses. Background technique [0002] Augmented reality (AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images, videos, and 3D models. The goal of this technology is to "seamless" real-world information and virtual world information. integrated. The physical information, which is difficult to experience in a certain time and space, is applied to the real world through computer simulation, and is perceived by human senses. Augmented reality comes in the form of head-mounted wearables. [0003] A wearable device is a hardware terminal that combines multimedia, sensor and wireless communication technologies with our daily wear to realize user interaction, life entertainment, human body monitoring and other functions. Wearable devices have the a...
