Abstract

The invention discloses an image processing method and device, equipment and a storage medium. The method comprises the steps that acquring a current frame image collected by a camera, and extractingvisual features of the current frame image; generating a feature vector of the current frame image according to the visual feature of the current frame image; dividing the feature vector of the current frame image into a plurality of sub-vectors, quantifying the plurality of sub-vectors, and generating a feature index of the visual feature of the current frame image; matching the feature index ofthe visual feature of the current frame of image with the feature index of the visual feature of each training image, and determining a matching feature pair of the current frame of image and each training image; wherein the feature index of the visual feature of each training image is obtained based on a sub-code book; and determining the training images of which the number of the matched featurepairs is greater than a first preset threshold value as similar images of the current frame of image. According to the technical scheme, rapid image recognition can be realized.

Description

technical field

[0001] The present disclosure generally relates to the technical field of computers, specifically to the technical field of image processing, and in particular to an image processing method, device, device, and storage medium. Background technique

[0002] In recent years, with the rapid development of semiconductor technology and the promotion of the wave of artificial intelligence, fast image recognition and tracking algorithms have become a research hotspot in the fields of augmented reality and robot positioning.

[0003] At present, in the process of image recognition, it is mainly implemented based on the tree-shaped BoW (Bag-of-words, bag-of-words) model. In order to achieve a better recognition effect in this way, a large-scale tree-shaped visual dictionary needs to be established, which leads to a long time-consuming image recognition process, and the memory usage of the tree-shaped visual dictionary is high. Use is limited. Contents of the invent...
