| titleOfInvention | A Cylindrical Image Matching Method Combining SURF Feature Extraction and Curve Fitting |
| abstract | The invention relates to a cylindrical image matching method combining SURF feature extraction and curve fitting, the steps are as follows: two images A and B to be matched are placed in the upper and lower positions in a left-aligned manner; Perform feature detection on two images; find a set of matching pairs; calculate the angle between the straight line and the horizontal direction determined by each matching pair in the feature point matching pair set, and the angle and Euclidean distance between two feature points in each matching pair , establish the angle set K of the image matching pair and the Euclidean distance set D of the image; perform curve fitting on the angle set K of the matching pair, the independent variable of the curve fitting is the abscissa X 1i of the matching pair, and the vertical axis of the curve fitting The coordinates are angle θ i , and false matches are eliminated. Curve fitting is performed on the Euclidean distance set D of the matching pair, and the independent variable of the curve fitting is the abscissa X 1i of the feature point of the matching pair in image A, and false matches are eliminated. The invention can more accurately eliminate the mismatch of cylindrical objects. |
