Abstract
A system and method of video match moving using minimal calibration is disclosed. A camera obtains an initial set of calibration images and a location image. Homographies are then determined between all the images using direct linear transformation. Camera pose locations of the images are determined from the homography matrices. Match moving augmentation is accomplished by obtaining an homography between a live image and the location image, either directly, or by combining an homography to a calibration image with that calibration image's augmentation homography. A virtual augmentation is then placed in the live image. The system evaluates the quality of each live image homography. If of sufficiently high quality, that live image is added to the set of calibration images. When a live image is received, the search for an homography typically starts with the calibration image located closest in camera pose space to the preceding live image.
