Improved real-time photogrammetric stitching

This work extends earlier work on the real-time photogrammetric stitching of staring arrays of high resolution videos on commercial off the shelf hardware. The blending is both further optimised for Graphics Processor Unit (GPU) implementation and extended from one to two dimensions to allow for multiple layers or arbitrary arrangements of cameras. The incorporation of stabilisation inputs allows the stitching algorithm to provide space stabilised panoramas. The final contribution is to decrease the sensitivity to depth of the stitching procedure, especially for wide aperture baselines. Finally timing tests and some resultant stitched panoramas are presented and discussed.
