Abstract

A method for high-quality stereo panorama mosaicing is presented. A scene is captured with an original three-camera system as stereo moving-picture sequences. The images are stitched together after improving their texture. The multi-purpose three-camera system features accurate frame synchronization between three channels and can be used outdoors through battery operation. For registration of the panorama stitching, under a newly investigated distortion-free condition, affine parameters are estimated through the overlapped areas using the steepest descent algorithm. The texture improvement has two steps : vertical resolution recovery by field integration and image enhancement by two dimensional quadratic Volterra filtering that satisfies Weber-Fechner's law. The presented method enables high-quality stereo mosaicing with accurate mutual disparities between channels and without visible distortion of textures.
