Abstract

The invention provides a template matching method and device, electronic equipment and a computer readable storage medium. The method comprises the following steps of determining an edge feature vector of a template image, decomposing the to-be-matched image into a pyramid image sequence, traversing and searching on each pyramid image in the pyramid image sequence from top to bottom, and determining the similarity between the edge feature vector and the feature vector on each pyramid image based on the projection length of the difference between the edge feature vector and the feature vector on each pyramid image, and based on the similarity between the edge feature vector and the feature vector on each pyramid image, determining a target image matched with the template image on the to-be-matched image. According to the method and the device, the calculation complexity of template matching can be reduced, and the precision of template matching can be improved.

Description

technical field [0001] The present application relates to image processing technology, and in particular to a template matching method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Template matching is the most basic and commonly used matching method in image processing technology, and it is one of the core algorithms for machine vision applications. As the first step of machine vision application, template matching makes the accuracy and speed of template matching determine the application prospect of machine vision applications. [0003] Template matching is widely used in object localization, object recognition, image registration, and robot guidance. The position coordinates, angle, scale and matching score of the target can be returned through template matching, and positioning guidance can be made according to the position information of template matching, and it is also possible to judge whether the matching target ...
