Document Type and Number:
WIPO Patent Application WO/2023/236508
Kind Code:
A1
Abstract:
The present application is specifically applied to the field of image processing. Provided are an image stitching method and system based on a billion-pixel array camera. The method comprises: a billion-pixel array camera photographing a target object, so as to acquire a first image to be subjected to stitching and a second image to be subjected to stitching; respectively performing feature point extraction on said first image and said second image, so as to determine first feature points and second feature points; acquiring a first moving speed of the billion-pixel array camera; acquiring a second moving speed of the target object; calculating a deviation rate on the basis of the first moving speed and the second moving speed; adjusting the first feature points and the second feature points on the basis of the deviation rate, so as to obtain first corrected feature points and second corrected feature points; matching the first corrected feature points and the second corrected feature points, so as to obtain a plurality of optimal feature point pairs; and performing screening on the plurality of optimal feature point pairs, and stitching said first image and said second image, so as to obtain a complete image. In this way, the present invention can improve the splicing efficiency and accuracy of images.
