Abstract:
1. A method of automatically converging a pair of images for use in a stereoscopic camera system including a pair of 2-D cameras, the method comprising: receiving a focal distance from metadata from each of the pair of 2-D cameras; calculating a system focal distance of the stereoscopic camera system by averaging the focal distances received from the pair of 2-D cameras; determining a center of interest using the calculated system focal distance of the stereoscopic camera system; receiving the pair of images from the pair of 2-D cameras, wherein each of the pair of images is generated by each of the pair of 2-D cameras using the focal distance; horizontally cropping each of the pair of images by a certain amount on opposite side of the images which adjusts directions of view of the pair of 2-D cameras substantially enough to converge at the determined center of interest, wherein the pair of images converges into a single stereoscopic image at the center of interest; and vertically cropping the pair of images to adjust for eccentricities of lenses in the pair of 2-D cameras using a look-up table of crop values defined for the lens at various levels of zoom.
