Problems solved by technology

[0007] However, limited by the size of the area that can be covered by a remote sensing image, especially when using high-resolution remote sensing images, it is necessary to investigate various resources in a certain administrative area, geographical division, watershed, etc. In the current situation and changing situation, only one scene of remote sensing images is far from meeting the requirements of practical applications, and the image sequence of multiple scenes with a certain overlap rate in spatial position is synthesized into one scene through fusion and splicing technology with seamless, New images with wide field of view and information of each image sequence have become a basic requirement for remote sensing images in practice

Embodiment 2

[0062] Embodiment 2: as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 and Figure 7 As shown, an image fusion stitching method based on a parallel computing algorithm, due to the limitation of the coverage of a scene remote sensing image, especially when using a remote sensing image with a high ground resolution To investigate the status and changes of various resources, the limitations of single-scene images are very obvious.

[0063] Fusion and splicing of multi-scene images into one scene image has become a basic operation process necessary for remote sensing images in practical applications. The traditional fusion stitching algorithm is based on the traditional serial computing algorithm, but for remote sensing image data, with the improvement of spatial resolution, the data volume of single scene image is getting larger and larger. When fusion splicing, limited by computer resources and traditional serial computing algorithms, it is more and mo...

Description

technical field [0001] The invention relates to an image fusion stitching method based on a parallel computing algorithm, which belongs to the technical field of image processing. Background technique [0002] Image stitching usually includes three basic steps of image preprocessing, image registration and image fusion. Image preprocessing mainly refers to the geometric distortion correction and noise suppression of the image, so that the reference image and the image to be stitched have no obvious geometric distortion. [0003] The image registration criterion is the most critical step in image mosaicing, and the quality of image registration methods is directly related to the efficiency and accuracy of image registration. At present, the most commonly used registration methods can be roughly divided into two categories: area registration method and feature registration method. [0004] Based on the area correlation registration method, its characteristic is to select a r...
