A system (1) for generating and displaying a continuous and real-time augmented reality scene corresponding to a user's current position and orientation, the system (1) consisting of:
- a head-worn device (10) for a user, comprising
- a mounting element (100) for stable attachment to the head, one or more sensors (101) for sensing physical characteristics of the user and the user's environment and outputting data corresponding thereto, the one or more sensors (101) selected from the group consisting of:
- a sonar (1010),
- an inclination sensor (1011) for determining spatial direction,
- a position sensor (1012) for determining absolute position of the user, and
- at least one an environmental sensor (1013) for sensing external environmental characteristics, wherein the at least one environmental sensor (1013) is selected from the group consisting of:
- a flow sensor, an air flow sensor, a temperature sensor, a smoke sensor, a motion sensor, and a presence sensor;
- an integrated computing and communication unit (103), and
- a display (102) for displaying the augmented reality scene;
- a reference data database (20) containing reference data, wherein the reference data is formed by sonar images and/or two-dimensional camera images of different spatial directions, wherein the data sensed by the one or more sensors (101) in one spatial direction can be matched with the reference data in the one spatial direction;
- a data storage unit (30) configured for storing at least image reference image pairs provided by the one or more sensors (101) matched in the spatial direction, the data storage unit (30) having a sub-unit for storing processed sensor data and/or the reference data;
- a fixed, static sensor assembly (40) and/or a fixed, movable sensor assembly (50) in communicative connection with the integrated computing and communication unit (103) for sensing physical characteristics of the environment, wherein the sensor assembly (40, 50) comprises a plurality of sensors whose fields of view are partially overlapping, and the reference data are data in a given spatial direction, continuously or predetermined, sensed by the installed, static sensor assembly (40) and/or the installed, movable sensor assembly (50), and/or data in a given spatial direction, continuously determined, sensed by the plurality of sensors;
- and
- an external processing unit (60) which comprises a display unit (601) displaying an augmented reality scene and/or the absolute position of the user, wherein the display unit (601) is in communicative connection with the integrated computing and communication unit (103) and/or an external computing and communication unit (600);
- wherein the integrated computing and communication unit (103) is in communicative connection with the one or more sensors (101), the reference data database (20), the data storage unit (30) and the display (102),
- wherein the sonar (1010) is arranged in a center of the head-worn device (10), and
- wherein the system further comprises a plurality of reference data databases (20), wherein each reference data database of the plurality of reference data databases contains different types of the reference data, wherein the different types of the reference data can be combined with each other, based on the spatial direction, to correspond to the data sensed by the one or more sensors (101).
