Abstract

The invention relates to a method and a system for stitching spatial domain images based on a weighted average method. The method for stitching the spatial domain images includes the steps: acquiring a weighted value calculation formula according to a preset weighted value rule and calculating a first weighted value and a second weighted value of each pixel in a stitching area according to the weighted value calculation formula; multiplying pixel values of optional pixels in different images in the stitching area with weighted values corresponding to the pixel values in the different images to obtain weighted pixel values, and adding the weighted pixel values to obtain stitching pixel values serving as pixel values corresponding to the pixels in the stitching area; and splicing image areas of the same portion of a first image and a second image into an area according to the stitching pixel values. Therefore, the weighted value calculation formula is universally used for optional stitching borders and optional stitching lines of overlap areas, and universality of the method is improved.

Description

technical field [0001] The invention relates to the field of image processing. In particular, it relates to a method and system for stitching airspace images based on a weighted average method. Background technique [0002] Due to the limitation of the camera's field of view, traditional imaging technology has been difficult to meet the needs of wide format, large field of view, super wide angle and even panoramic images. In order to solve this problem, image stitching technology is used to stitch together two or more images with partial scene overlapping to generate an image with a wider viewing angle or a 360° panoramic image. Among them, the main technology used in the image stitching technology is the image stitching technology, which is used to stitch together the overlapping areas of the images to be stitched, so as to ensure that the overlapping areas of the images can change continuously, the transition is natural and there is no visible stitching line. [0003] Th...
