Seamless bridging ar-device and ar-system

Abstract

An Augmented Reality (AR)-device, including a visual sensor for capturing an environment of the AR-device, a display providing a real view of the environment, and overlays onto the real view according to AR-data including at least one of design data and measured data, a computer 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 by identifying a reference system based on at least one identification feature captured by the visual sensor, determining a pose of the AR-device relative to the identified reference system, and maintaining the referenced status in case of loss of visual contact between the visual sensor and the identification feature, based on a Visual Localisation and Mapping (VSLAM)-process.
