Abstract

The present invention relates to a method and device for image stitching, comprising: acquiring a first image and a second image, where there is an overlapping area between the first image and the second image; The area outside the processing area is the remaining area; obtain the brightness component or chrominance component of each pixel in the remaining area, and obtain the weight of each adjacent pixel point pair in the remaining area; set the adjacent pixel point pair in the area to be processed The weight of the adjacent pixel point pair in the area to be processed is greater than the weight value of the adjacent pixel point pair in the remaining area; among the stitching paths in the overlapping area, the stitching path with the smallest stitching line intensity is determined as the best stitching line, performing image stitching on the first image and the second image along the optimal stitching line. According to the image splicing method and device of the present invention, the stitching line can be avoided from the area to be processed, the splicing of the unprocessed area can be guaranteed to be natural, and the user's subjective experience of browsing images can be improved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image splicing method and device. Background technique [0002] Image mosaic technology includes two key links of image registration and image fusion. The goal of image registration is to find out the transformation relationship between two or more images with overlapping areas, establish a mathematical model of image coordinate transformation, and transform multiple images into a coordinate system by solving the parameters of the model. Image fusion technology is used to solve the problem of inaccurate registration caused by geometric correction, dynamic scenes or lighting changes, and merge adjacent images into one image. [0003] In the process of image fusion, the existing technology uses the best suture line technology to find an optimal suture line in the overlapping interval of multiple images, so that the energy difference between the two images on the suture l...
