SUBSURFACE UTILITY VISUALIZATION

The invention relates to a method for providing an augmented view of an underground infrastructure in a real world scenery. It comprises a deriving of real time real world images of the real world scenery, deriving a location information for the field of view of those images, deriving a six degree of freedom spatial reference of the real world images and their image content by image processing and an inertial measurement unit. With a deriving of a geospatial information of underground infrastructure in vicinity of the location information from an underground infrastructure database, a calculating of a virtual rendering of the underground infrastructure is done with a same virtual field of view and perspective as the field of view of the real world images. With an augmenting of the virtual rendering in the real world images, a providing of resulting augmented images by a two or three dimensional vision unit is established.According to the invention, the virtual rendering and the augmenting is done with a determining of a ground surface in the real world images and a transforming of the ground surface by a semi-transparent virtual representation of the ground surface, wherein the rendering of the virtual underground infrastructure is visualized below the virtual ground surface in the augmented image.
