Abstract

The invention relates to an image processing method, device and terminal, and the method comprises the steps: carrying out the scale change of a first image and a second image, and obtaining space representation sequences at the two scales, wherein the first and second images have overlapping parts; respectively extracting feature points based on pixels in the two space representation sequences, and obtaining feature points of all scales corresponding to the first and second images; carrying out the clustering of the feature points of all scales into different clusters based on the similarity of feature points of the same scale; respectively determining matching points based on the feature points in the clusters in the first and second images; and carrying out jointing and fusion of the two images based on the matching points. According to the embodiment of the invention, the method achieves the effective detection of cracks and grooves on a highway pavement, is high in accuracy, is good in instantaneity, and facilitates the formulation of a repair strategy for a broken pavement.

Description

technical field [0001] The present disclosure relates to the technical field of image detection, and in particular, to an image processing method, device, and terminal. Background technique [0002] In highway pavement damage detection projects, binocular vision robots are usually used to capture images, and based on GPS (Global Positioning System, Global Positioning System) positioning technology, the two captured images are stitched together. However, due to errors in the GPS positioning itself, the accuracy of the stitched images is also affected. Contents of the invention [0003] In order to overcome the problems existing in related technologies, the present disclosure provides an image processing method, device and terminal. [0004] According to a first aspect of an embodiment of the present disclosure, an image processing method is provided, including: [0005] Scale transforming the first image and the second image respectively to obtain two multi-scale spatial ...
