opencv采集图像并进行轮廓检测

#include "stdafx.h"#include <opencv2\opencv.hpp>#include <iostream>#include <string>using namespace std;using namespace cv;int main(){char c;VideoCapture inputVideo(0);    //0为外部摄像头的ID，1为笔记本内置摄像头的IDMat src;for (;;){inputVideo >> src;//获取一帧图像Mat src1 = src.clone();Canny(src, src1, 150, 100, 3);//进行轮廓检测imshow("input", src1);//显示检测结果c = waitKey(10);if (c == 27) break;}return 0;}
