Problems solved by technology

[0005] Since the above-mentioned processing method completely depends on the manual preset template parameters of each resolution, once the template parameters are set and put into use, it cannot be applied to the image matching of new resolutions, because manual preset template parameters often cannot Compatibility Considering all possible resolutions, the compatibility of the above processing methods is not very good in practical applications. Moreover, the labor and time costs of the above processing methods are very high, which also greatly limits the application of template matching technology. application

Abstract

The embodiment of the invention discloses a template matching method, device and equipment and a medium. The method comprises the steps of obtaining a first screenshot image of an application runningon a terminal; intercepting a region of interest from the first screenshot image according to a standard detection region position corresponding to the template image; carrying out template matching on the region of interest by adopting the template sub-image corresponding to each zoom level to obtain an optimal matching position and a matching confidence coefficient corresponding to each zoom level; selecting the scaling level with the highest matching confidence, and taking the scaling coefficient corresponding to the scaling level and the optimal matching position as a group of template reference parameters; determining template target parameters of the template image adaptive terminal according to the template reference parameters; and carrying out template matching on a second screenshot image of the running application on the terminal according to the template image and the template target parameter. According to the method, the compatibility of multi-resolution images can be effectively improved, and the labor cost and the time cost which are consumed in the template matching process are reduced.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to a template matching method, device and medium. Background technique [0002] Template matching is a technique to find sub-images similar to the template image in another image based on the template image. It has important applications in many fields such as machine vision, target tracking, object recognition, and game image processing. [0003] In practical applications, when the same image is displayed on terminals with different resolutions due to different terminal resolutions, the layout of elements in the image will be different, that is, the absolute position and size of the elements in the image will be different. As a result, if the same template image is directly used to match images displayed on terminals with different resolutions, the matching effect is not very good. [0004] In order to be compatible with the template matching of multi-resolutio...
