1.定义和输出二维点
代码如下：
#include <opencv2/opencv.hpp>
#include"opencv2/highgui/highgui.hpp"
#include<iostream>
using namespace std;
using namespace cv;
int main(int argc,char** argv)
{
?? ?Point2f p(6, 2);
?? ?cout << "[二维点]p=" << p << ";\n" << endl;
}
?
?2.定义和输出三维点
#include <opencv2/opencv.hpp>
#include"opencv2/highgui/highgui.hpp"
#include<iostream>
using namespace std;
using namespace cv;
int main(int argc,char** argv)
{
?? ?Point3f p3f(8, 2,0);
?? ?cout << "[三维点]p3f=" << p3f<< ";\n" << endl;
}
?
3.定义和输出基于Mat的std::vector
?
#include <opencv2/opencv.hpp>
#include"opencv2/highgui/highgui.hpp"
#include<iostream>
using namespace std;
using namespace cv;
int main(int argc,char** argv)
{
?? ?vector<float> v;
?? ?v.push_back(3);
?? ?v.push_back(5);
?? ?v.push_back(7);
?? ?cout << "[基于Mat的vector]shortvec=" << Mat(v) <<";\n"<< endl;
}
?4.定义和输出std::vector点
#include <opencv2/opencv.hpp>
#include"opencv2/highgui/highgui.hpp"
#include<iostream>
using namespace std;
using namespace cv;
int main(int argc,char** argv)
{
?? ?vector<Point2f> points(20);
?? ?for (size_t i = 0; i < points.size(); ++i)
?? ??? ?points[i] = Point2f((float)(i * 5), (float)(i % 7));
?? ?cout << "[二维点向量]points" << points << ";";
}
?
