Abstract
A self calibrating stereo camera includes first and second spatial transform engines for directly receiving first and second images, respectively, of an object. The first and second spatial transform engines are coupled to a stereo display for displaying a fused object in stereo. A calibration module is coupled to the first and second spatial transform engines for aligning the first and second images, prior to display to a viewer. The first and second point extracting modules, respectively, receive the first and second images for extracting interest points from each image. A matching points module is coupled to the first and second point extracting modules for matching the interest points extracted by the first and second point extracting modules. The calibration module determines alignment error between the first and second images, in response to the interest point matches calculated by the matching points module.
