Claim 6:
7. A system of organically generating a camera-pose map, comprising:
a digital video camera located at a fixed location at an event venue;
a programmable digital computer functionally connected to said digital video camera;
designating, by an operator, a target location, said target location being an area deemed suitable for augmenting with a virtual augmentation;
obtaining, by said operator using said computer and said camera, a target image of said target location within said event venue immediately prior to a commencement of an event at said event venue;
designating a camera-pose of said target image to be an origin of a camera-pose space;
obtaining and calibrating, by said operator using said computer and said camera, at least one calibrated camera-pose image, said calibrated camera-pose image having a calculated camera-pose location in said camera-pose space and a calculated augmentation homography to said target image; and,
said computer being programmed to automatically preform the functions of:
obtaining, during an event at said event venue, a current image of said event venue using said fixed camera;
determining a current-to-calibrated homography of said current image to one of said calibrated camera-pose images having a camera-pose location closest to an estimated camera-pose location of said current image;
calculating a camera-pose location of said current image using said current-to-calibrated homography and said augmentation homography of said calibrated camera pose image;
calculating a distance in camera-pose space between said current image and said one of said camera-pose images; and,
when said distance in camera-pose space is less than a predetermined threshold, designating said current image as a calibrated camera-pose image.
