Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found the following problems in the prior art: the existing image positioning method has the problem of low efficiency
For example, in template matching, the positioning of the best position of the image is determined by means of a sliding window, so when the size difference between the template image and the target image is large, the number of iterations of the sliding window is tens of thousands of times, so Existing image localization methods have the problem of low efficiency

Embodiment Construction

[0044] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0045] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0046] At present, the existing image localization methods include the following two methods: one of the image localization methods uses a Siamese network, uses two neural network modules to extract features from the template image and the reference image, and then uses a similarity calculation function The degree of difference between the features of the temp...

Abstract

The embodiment of the invention provides an image positioning method and device, a storage medium and electronic equipment. The image positioning method comprises the steps of obtaining a template image and a target image; inputting the template image and the target image into a pre-trained image positioning model to obtain a first sub-optimal matching position of the template image and the target image in the first direction, the second sub-optimal matching position is used for representing a second sub-optimal matching position of the template image and the target image in the second direction, a first similarity corresponding to the first sub-optimal matching position, and the second similarity corresponds to the second sub-optimal matching position, wherein the first direction is perpendicular to the second direction; and determining an image positioning result according to the first sub-optimal matching position, the second sub-optimal matching position, the first similarity and the second similarity. By means of the technical scheme, the image positioning efficiency can be improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, and more specifically relates to an image positioning method, device, storage medium and electronic equipment. Background technique [0002] Image localization has always been an important and concerned technology in the field of computer vision, and it can be widely used in many fields such as object tracking, image retrieval, and object detection. [0003] At present, the existing image localization method is realized through a template matching (Template Matching) algorithm. For example, by sliding the window in the target image, the similarity between the regions in each window and the template image is calculated one by one, so that the most similar position and similarity between the target image and the template image can be finally obtained. [0004] In the process of realizing the present invention, the inventors found the following problems in the prior art: the exi...
