Abstract:
1. An apparatus for providing navigational information associated with locations of objects comprising: an imaging device configured to acquire image data, the imaging device calibrated to enable transformation between three-dimensional coordinates of the objects in space and corresponding two-dimensional image coordinates of the image data in an image plane; a visual display coupled to the imaging device and configured to display the image data; a position measuring device disposed in a fixed position relative to the imaging device and configured to determine position information associated with the imaging device; one or more tilt sensors configured to measure a pitch and a roll of the imaging device; an orientation device configured to determine orientation information associated with the imaging device; and a rendering system coupled to the visual display, the position measuring device, the one or more tilt sensors, and the orientation device, the rendering system configured to: obtain three-dimensional coordinates of a location of an object; using the three-dimensional coordinates, calibration of the imaging device, and one or more transformations, determine two-dimensional image coordinates of the image data in the image plane that are associated with the location of the object; and provide a navigational graphic on the visual display oriented relative to the two-dimensional image coordinates of the image data in the image plane.
