Abstract

Starting an experiment about image stitching of blade-shape hole. Firstly, Focusing on algorithms of feature point detection. Harris, SIFT, and SURF are the main feature point detection algorithms. All of them are used to detect feature points on the same image, and analyze the precision of it and time-consuming. Then compare algorithm of the points match (brute force and KNN, brute force and crosscheck, K-D tree and KNN) by SSIM and line profile. Image fusion is determined based on pixel weighting, and transformation matrix is gained by RANSAC. Last, the system uses the Harris algorithm to detect feature points, and uses brute force and the KNN algorithm to match them. Verify the algorithm of blade-shaped hole image stitching is effective, and lay foundation for the next work of this project.
