Augmentation of a dynamic terrain surface
First Claim
1. A method for providing augmented reality for a site having a dynamically changing terrain surface comprising:
- capturing a live georeferenced terrain surface topography for the site using a sensor;
capturing an image of the site using a camera;
determining a georeferenced camera pose of the camera using a tracking system;
aligning a georeferenced three-dimensional (3-D) model for the site with the live georeferenced terrain surface topography; and
using at least the captured image, the georeferenced camera pose, the georeferenced 3-D model and the live georeferenced terrain surface topography, to create an augmented view of the site that shows graphical representations of subsurface features, wherein a least a portion of the graphical representations are dynamically conformed to the contours of the terrain surface based on the live georeferenced terrain surface topography.

Abstract
In one embodiment, an augmented view is generated that accounts for dynamically changing terrain surface at a site. A sensor captures live georeferenced terrain surface topography for the site. A camera captures an image of the site. Further, a tracking system determines a georeferenced camera pose of the camera. An augmented reality application aligns a georeferenced three-dimensional (3-D) model for the site with the live georeferenced terrain surface topography. Then, using at least the captured image, the georeferenced camera pose, the georeferenced 3-D model and live georeferenced terrain surface topography, the augmented reality application creates an augmented view of the site that shows graphical representations of subsurface features. At least a portion of the graphical representations are dynamically conformed to the contours of the terrain surface in the image based on the live georeferenced terrain surface topography. The graphical representations may include virtual excavation and/or virtual paint markings.
