[0032] The technical solutions and effects of the present invention will be described in further detail below with reference to the accompanying drawings.
[0033] The realization steps of the present invention are as follows:
[0034] Step 1, input query image I 0 and the target image database S.
[0035] Step 2, corner detection. After binarizing the query image and the image in the image database, extract the edge and filter it, and use the method based on the maximum value of the edge curvature to detect the corner point; for the query image I 0 Detect the corner points and get the corner point set P of the query image 0 ={P 0l},l=1,2,...,m, for any image I in the image database S j (j=1,2,…,k) detect the corners and get I j The set of corner points P j ={P jv}, v=1,2,...,n, where m, n are I 0 and I j The number of corner points; (orange is the added content)
[0036] (2.1) Edge extraction. Perform a binarization operation on the image and extract the edge curv...
