Problems solved by technology

[0002] The traditional image traversal algorithm is similar to the traversal of the matrix, starting with the first pixel in the upper left corner as the origin of the coordinates, and traversing each pixel until the pixel in the lower right corner. This is a feasible brute force algorithm , can also solve the problem, but we found in the experiment that each time the traversal starts from the upper left corner, each pixel needs to be traversed one by one to find the feature point, and the efficiency is very low

Abstract

The invention discloses an image traversal algorithm for rapid image recognition and feature matching. The method comprises: enabling a computer to obtain coordinates of all pixel points on an image and RGB values of corresponding colors, converting graying of the color image into a binary grayscale image, carrying out recognition from the upper left corner of the image, and finding out a pixel point corresponding to a certain pixel point of a feature graph to serve as a recognition point; selecting the identification point as a traversal coordinate origin, and designing the image in a regional and layered manner; and dividing the image into a plurality of regions by taking the traversal coordinate origin as a center, carrying out traversal from a certain region according to a clockwise direction, and searching other pixel points of the feature graph, wherein a traversal coordinate point of each layer of the image is a coordinate point set of the same level of each region. According tothe invention, the new identification point is searched from the coordinate close to the last identification point, so that the efficiency of image identification and feature matching is greatly improved.

Description

technical field [0001] The present application relates to the technical field of image recognition, in particular to an image traversal algorithm for rapid image recognition and feature matching. Background technique [0002] The traditional image traversal algorithm is similar to the traversal of the matrix, starting with the first pixel in the upper left corner as the origin of the coordinates, and traversing each pixel until the pixel in the lower right corner. This is a feasible brute force algorithm , can also solve the problem, but we found in the experiment that each time the traversal starts from the upper left corner, each pixel needs to be traversed one by one to find the feature point, and the efficiency is very low. Contents of the invention [0003] The present application provides an image traversal algorithm for rapid image recognition and feature matching, so as to improve the efficiency of image recognition and feature matching. [0004] In order to solve...
