c++ - OpenCV C++ "CvSURFParams was not declared in this scope"错误

Question

我想在 OpenCV C++ 中实现 SURF 算法。我的包括:

#include <stdio.h>
#include <iostream>
#include "opencv2/core/core.hpp"
#include "opencv2/features2d/features2d.hpp"
#include "opencv2/highgui/highgui.hpp"
#include "opencv2/opencv.hpp"
#include "opencv2/nonfree/features2d.hpp"

当我运行这行代码时

CvSURFParams params = CvSURFParams(500, 1);

我收到“CvSURFParams 未在此范围内声明”错误。

请帮帮我

Answer 1

很可能您使用的是 C api，请改用 cv::SURF

或者，如评论中所建议的，正确的语法是 CvSURFParams params = cvSURFParams(500, 1);
