The invention relates to an
image stitching processing system, which belongs to the field of
image processing, and is characterized in that an image reading unit, an overlapping region unit, a preprocessing unit, an optimal stitching line unit, a feature location unit, a
feature matching unit, and a deformation propagation and image reconstruction unit are arranged in a digital
processing circuit, wherein the image reading unit is used for reading two adjacent images from an
image sequence; the overlapping region unit is used for acquiring an overlapping region of the two images; the preprocessing unit is used for preprocessing color of the overlapping region; the optimal stitching line unit is used for obtaining an optimal stitching line in the overlapping region; the feature location unit is used for detecting feature points in an optimal stitching line neighbourhood; the
feature matching unit is used for matching the detected feature points; and the deformation propagation and image reconstruction unit is used for obtaining a
deformation vector of each pixel point of each image, obtaining a gradient field of each image, and reconstructing a stitched image according to the gradient field. According to the
image stitching processing system, the optimal stitching line is used as the most important image feature, so that the limitation of a shape of the overlapping region is solved, a lapped seam can be well eliminated in color and structure, and a real-
time processing requirement can be met by utilizing an acceleration
algorithm.
