11月开发总结

11.12

头文件中不要加任何命名空间，会存在很多重定义问题

11.13 surf特征点提取写法

cv::Ptr surfDetector = cv::xfeatures2d::SurfFeatureDetector::create(10);

surfDetector->detect(center_img, tmp_center);

surfDetector->detect(Best_img_i, tmp_image);

cv::Ptr detector = cv::xfeatures2d::SurfDescriptorExtractor::create();

detector->detect(image1, tmp_center, descriptor_center);

detector->detect(image2, tmp_image, descriptor_image);

和下面的写法不能混淆

cv::Ptr detector = cv::xfeatures2d::SURF::create(10, 4, 3, true, true);

std::vector keypoints1, keypoints2;

cv::Mat src_vector, temp_vector;//用来存放特征点的描述向量

//找到特征点并计算特征描述子(向量)
detector->detectAndCompute(img1, cv::Mat(), keypoints1, src_vector);

detector->detectAndCompute(img2, cv::Mat(), keypoints2, temp_vector);
