AUGMENTED-REALITY DEVICE AND SYSTEM WITH SEAMLESS BRIDGING

The invention relates to an Augmented Reality (AR)-device, comprising a visual sensor configured for capturing an environment of the AR-device, a display configured for providing a real view of the environment, and overlays onto the real view according to AR-data, wherein the AR-data comprise at least one of design data and measured data, a computer configured for reading and controlling the visual sensor, at least one of receiving, generating and storing the AR-data, and identification features which are assigned to each of a plurality of reference systems, generating the overlays, establishing a referenced status of the AR-device relative to each of the reference systems in each case by identifying a reference system based on at least one identification feature captured by the visual sensor, and determining a pose of the AR-device relative to the identified reference system, and maintaining the referenced status even in case of loss of visual contact between the visual sensor and the at least one identification feature, based on a Visual Localisation and Mapping (VSLAM)-process.
