AR glass is a comprehensive platform. The whole workflow includes four key technologies: target recognition, slam, graphics rendering and optical display.
Target recognition is the first step of AR glasses workflow, that is, we first select a target in the surrounding environment, and then anchor the target to superimpose virtual information. Thanks to the progress of deep learning technology, target recognition in security scene has been relatively mature.
Rendering is a key step to generate 2D images from virtual information (generally 3D model) according to the set camera, light, material and other projections, so as to make ar fuse virtual and real and improve people's visual experience. Optical display is the most important part of AR wearables. In addition to ensuring visual experience, how to meet the convenience of glasses wear all day has become a major technical challenge in AR near eye display field. The new AR will be widely used in more fields. AR devices, like mobile phones, may also become an indispensable part of daily life.
