Embodiment Construction

[0041] Augmented reality technology is to superimpose virtual information into the real world to enhance specific objects in the real world, so that users can receive more real-world information. And because the real world is a three-dimensional world, the virtual information needs to be superimposed on the real scene correctly. This key technology is completed by the front-end augmented reality equipment. In order to solve the problem of front-end and back-end information synchronization and clear guidance, the present invention provides an augmented reality remote support method, which adds data interaction on the basis of video and voice interaction, and the back-end expert equipment can reconstruct the front-end according to the interactive data The model information of the scene is fully matched with the real scene, so that the back-end expert equipment also has the same first-person perspective information as the front-end user equipment. Experts can operate or add annot...

Abstract

The invention discloses an augmented-reality remote guidance method and system. A front-end augmented reality device superposes virtual models of a guidance object and a guidance animation on a real object for displaying; the front-end augmented reality device collects video information, audio information and interaction data of a real scene and then transmits the information and data to a back-end expert device; the back-end expert device reconstructs attitudes and display visual angles of the guidance object and the guidance animation according to the virtual mode stored by the back-end expert device and the received interaction data; and the back-end expert device receives guidance information inputted by an expert and synchronizes the guidance information to the front-end augmented reality device, and the front-end augmented reality device carries out displaying by combining the virtual models. The front end and the back end employs a three-layer network transmission mode. When thenetwork environment is not good, a video layer is turned off or quality-reduced transmission is carried out on the video layer and / or audio layer. Therefore, the front-end and back-end expert devicesobtain clear information references, so that the effectiveness of remote guidance is improved.

Description

technical field [0001] The invention relates to the technical field of augmented reality, in particular to a remote guidance method and system for augmented reality. Background technique [0002] The augmented reality remote guidance system is to solve the problem of allowing remote experts to have the same immersive experience as the on-site staff, and to give the on-site staff the most direct and accurate guidance combined with the on-site reality. [0003] When working on the front-end, many times you will encounter problems that the front-end personnel cannot solve. At this time, you need to consult the back-end experts. At present, the goal can be achieved through voice interaction (telephone), or video + voice interaction (real-time video). However, these two methods will be very limited, the interaction between the front-end and the front-end personnel will be very inconvenient, and the information will not be clearly referred to. It is difficult for experts to let ...
