An embodiment of the present invention discloses an image matching method. The method includes: acquiring a first target image and a second target image to be matched; calculating the first target image and the second target image respectively by using a preset feature calculation method At least one feature value of the target image, the at least one feature value includes at least one of a block mean vector, an average hash feature value, a perceptual hash feature value, and / or a differential hash feature value; Calculate the similarity value between the first target image and the second target image by at least one feature value of a target image and the second target image; determine the similarity between the first target image and the second target image through the similarity value The matching result of the second target image. The image matching method of the present invention can accurately determine the matching result between target images, and effectively improves the efficiency of image matching. In addition, an image matching apparatus, computer equipment and storage medium are also provided.
Description
technical field [0001] The present invention relates to the technical field of computer vision, and in particular, to an image matching method, apparatus, computer equipment and storage medium. Background technique [0002] In the process of financial management, a large number of invoices and other bills need to be audited. At present, a large number of financial computerization and reimbursement fee control systems have appeared, and financial personnel are increasingly relying on online electronic images for financial compliance audits, and it is necessary to match online and offline bill images. [0003] The prior art is mainly based on the scheme of comparing the shape features of the collected bill images after extraction. For example, for the detection of lines in the bill image, or using edge detection filters to perform operations and extract features for comparison. However, for financial processing scenarios, due to the variety of document styles and complex edg...
