opencv3中SURF特征点检测

#include<iostream>#include<opencv2/opencv.hpp>#include<vector>using namespace cv;using namespace std;int main(){Mat srcImage = imread("mofang1.jpg");imshow("【原图】", srcImage);//首先得到特征点的集合//先配置参数vector<KeyPoint> keyPoint;//在库中：typedef SURF SurfFeatureDetector;   typedef SURF SurfDescriptorExtractor;所以三者是等价的（别名）SURF surf(1000);//1000为检测算子的阀值surf.detect(srcImage, keyPoint, Mat());//开始绘制特征点Mat dstImage;dstImage.create(srcImage.size(), srcImage.type());drawKeypoints(srcImage, keyPoint, dstImage, Scalar(-1), 2);imshow("【检测到特征点后的图像】", dstImage);waitKey(0);return 0;}
