Abstract

The invention discloses an image matching method and system based on image matching and a storage medium. According to the image matching method based on image matching, through feature point extraction and feature point screening, image construction is completed; an image matching method is adopted, matching is carried out by adding attributes of edges, even if local features are difficult to distinguish due to similarity or the local features of the same object in the two images change, feature matching can be accurately achieved through distance relation constraints between feature points,the robustness of the matching method is effectively enhanced, and matching precision is guaranteed. Meanwhile, compared with a classical image matching technology such as an integer projection fixedpoint method (IPFP) and a step-by-step allocation algorithm (GA), the method adopts an advanced fast continuous projection fixed point iteration method to solve the optimal solution, a new projectionmethod is provided, the calculated amount is simplified in the optimization process, the speed of the image matching method is greatly improved, and the accuracy is improved to a certain degree on thebasis of the high accuracy of the image matching technology.

Description

technical field [0001] The invention relates to the fields of computer vision and pattern recognition, in particular to the field of image processing technology, especially an image matching method, system and storage medium based on graph matching. Background technique [0002] With the rapid development of multimedia technology, images have become an important carrier of information transmission, and digital image processing technology has become more and more important. Among them, image matching technology has become the focus of people's attention in recent years. Because other research directions of digital image processing technology, such as image recognition, image retrieval, object recognition, and object tracking, are further developed on the basis of image matching technology. It can be said that the progress of image matching technology can drive the overall development of digital image processing technology. [0003] However, image matching technology is not o...
