Abstract: An image stitching apparatus, an image processing chip and an image stitching method are provided. The image stitching apparatus includes a motion detection circuit, a determination circuit and a stitching circuit. The motion detection circuit performs motion detection on an overlapping area between a first image and a second image that are to undergo stitching to obtain a motion area having a moving object in the overlapping area. The determination circuit calculates a target stitching line using a constraint of avoiding the motion area. The stitching circuit stitches the first image and the second image according to the target stitching line to obtain a stitched image.

Abstract: An image stitching method and an image stitching device for stitching a first image and a second image are presented. The image stitching method includes: calculating, according to pixel values of the first image and the second image in an overlapping area, a plurality of costs respectively corresponding to a plurality of positions in the overlapping area; calculating, according to the plurality of costs and relative distances between the plurality of positions, a plurality of forward regularized cumulative costs respectively corresponding to the plurality of positions in the overlapping area; determining a seam in the overlapping area according to the plurality of forward regularized cumulative costs, wherein the seam includes a plurality of stitching positions; and stitching the first image and the second image on the basis of the seam to generate a stitched image.
