Method and system for geo-referencing at least one sensor image

Computer program product for geo-referencing at least one sensor image, the computer program product comprising at least one computer-readable storage medium having computer-readable program code portions embodied therein, the computer-readable program code portions comprising:

• an executable portion configured for generating said at least one sensor image of a first scene with at least one sensor;
• an executable portion configured for accessing a 3D model of the environment comprising geo-coded 3D coordinate data and related to at least one second scene, said second scene encompassing said first scene;
• an executable portion configured for matching the sensor image with the 3D model find a section of the 3D model where there is a match between the first and the second scenes;
• an executable portion configured for geo-referencing the sensor image based on the geo-coded 3D coordinate data of the found section of the 3D model;
• and
• an executable portion configured for determining a measure related to an uncertainty in the matching between the sensor image and the 3D model.

System (200) for geo-referencing at least one sensor image, said system comprising:

• at least one sensor (203) arranged to capture at least one image of the first scene;
• a memory (204) for storing a 3D model comprising geo-coded 3D coordinate data;
• and
• a processing unit (205) configured to access the 3D model, to match the sensor image with the 3D model so as to find a section of the 3D model where there is a match, to geo-reference the sensor image based on the geo-coded 3D coordinate data of the found section of the 3D model, and to determine a measure related to an uncertainty in the matching between the sensor image and the 3D model.
