Embodiment

[0073] In industrial automatic detection and collection devices, the collection range of a single camera is limited, and most of them will use block collection and post-splicing to collect complete images. Image registration and image fusion are two core steps. Image registration uses the Harris corner detection algorithm to determine enough registration points to find the mapping relationship between the image pixels of the two images; image fusion uses wavelet technology for fusion In order to be able to integrate the multi-band information of a single sensor or the information provided by different sensors to enhance the transparency of the information in the image, improve the accuracy, reliability and utilization of interpretation, and form a clear, complete and accurate image of the target Information description.

[0074] Such as figure 1 Shown is a flowchart of the present invention, and the method is realized by the following methods:

Abstract

The invention discloses an online image splicing and fusing method based on a wavelet technology. The method comprises the following steps of carrying out image registration processing on an acquiredoriginal image, and carrying out image fusion on the registered image; carrying out image registration processing on the original image; using an image registration algorithm of a Harris algorithm tofind a position corresponding to a template or a feature point in the to-be-spliced image in the reference image; according to the corresponding relation between the template or the image features, finding the positions of the template or the feature point in the two images, unifying the coordinate transformation, and for different images, enabling the mathematic models to be different and the coordinate systems to be different, by a transformation model for unifying multiple coordinate systems, splicing multiple images in one coordinate system; and performing image fusion on the registered images, and eliminating the phenomena of seams and blurring after the images are spliced by adopting an image fusion algorithm of a wavelet transform technology. The method is wider in application rangeand relatively higher in automation degree, and can satisfy the current most image splicing requirements.

Description

technical field [0001] The invention relates to an online image splicing and fusion method based on wavelet technology. [0002] technical background [0003] In the cloth printing and dyeing industry, the detection of color difference is a particularly important production link. Due to the width of the cloth and the limitations of the camera device, it is necessary to use image stitching technology to fuse and stitch the collected images to generate a complete set. images to ensure the accuracy and efficiency of subsequent color difference detection. [0004] Image stitching, that is, stitching images with overlapping edges into one image. At present, in the process of image mosaic, it is simple to overlap images with overlapping edges. The images spliced ​​in this way have low smoothness and unnatural transition, which is likely to cause visual discomfort. Contents of the invention [0005] 1, the purpose of the present invention [0006] Based on the technical proble...
