opencv打开双目

1，打开两个单目，拼成双目

#include <opencv2/opencv.hpp>
#include <opencv2/opencv_modules.hpp>
#include <iostream>using namespace cv;
using namespace std;//int main17051000()
int main()
{VideoCapture cap0(0), cap1(1);Mat image0, image1;cap0.set(CV_CAP_PROP_FRAME_HEIGHT, 240);cap0.set(CV_CAP_PROP_FRAME_WIDTH, 320);cap1.set(CV_CAP_PROP_FRAME_HEIGHT, 240);cap1.set(CV_CAP_PROP_FRAME_WIDTH, 320);Mat imageTwo(240, 320 * 2, CV_8UC3);Rect image0R(0, 0, 320, 240);Rect image0L(320, 0, 320, 240);Mat image0R1 = imageTwo(image0R);Mat image0R2 = imageTwo(image0L);if (cap0.isOpened()){while (true){cap0 >> image0;//blur(image0, image0, Size(5, 5));//Canny(image1, image1, 0.2, 2);image0.copyTo(image0R1);imshow("image0", image0);imshow("imageTwo", imageTwo);waitKey(1);}}if (cap0.isOpened() & cap1.isOpened()){while (true){cap0 >> image0;cap1 >> image1;//blur(image0, image0, Size(5, 5));//Canny(image1, image1, 0.2, 2);image0.copyTo(image0R1);image1.copyTo(image0R2);imshow("image0", image0);imshow("image1", image1);imshow("imageTwo", imageTwo);waitKey(1);}}else{cout << "cannot open camera" << endl;}getchar();return 0;
}int main2()
{int rows = 480, cols = 640;cv::Mat image = cv::imread("nature.jpg");if (!image.data){cout << "There is no picture" << endl;getchar();return false;}Size imageSize = image.size();Mat imageTwo = Mat(imageSize.height, imageSize.width * 2, CV_8UC3);Rect imageLeft(0, 0, imageSize.width, imageSize.height);Rect imageRight(imageSize.width, 0, imageSize.width, imageSize.height);//Mat mLeftView = m_mView(cv::Rect(0, 0, 640, 480));Mat imLeft = imageTwo(imageLeft);Mat imRight = imageTwo(imageRight);image.copyTo(imLeft);image.copyTo(imRight);if (image.data){cv::imshow("image", imageTwo);cv::waitKey();}else{std::cout << "there is no picture!" << std::endl;}getchar();return 0;
}

2，以前opencv打开相机的写法

#include <opencv2/opencv.hpp>
#include <stdio.h>
#include <iostream>#define WIDTH  640
#define HEIGHT 480using namespace std;
using namespace cv;int main4()
{CvCapture *capture1 = NULL, *capture2 = NULL; //capture1 <-> left, capture2 <-> rightIplImage* imageLeft;IplImage* imageRight;capture1 = cvCaptureFromCAM(0);assert(capture1 != NULL);//   cvWaitKey(100);capture2 = cvCaptureFromCAM(1);assert(capture2 != NULL);cvSetCaptureProperty(capture1, CV_CAP_PROP_FRAME_WIDTH, WIDTH);cvSetCaptureProperty(capture1, CV_CAP_PROP_FRAME_HEIGHT, HEIGHT);cvSetCaptureProperty(capture2, CV_CAP_PROP_FRAME_WIDTH, WIDTH);cvSetCaptureProperty(capture2, CV_CAP_PROP_FRAME_HEIGHT, HEIGHT);while (1){imageLeft = cvQueryFrame(capture1);imageRight = cvQueryFrame(capture2);Mat viewL(imageLeft), viewR(imageRight);imshow("viewL", viewL);imshow("viewR", viewR);waitKey(3);}cvReleaseCapture(&capture1);cvReleaseCapture(&capture2);return 0;
}int main()
{//main1();VideoCapture ML(0);VideoCapture  MR(1);ML.set(CV_CAP_PROP_FRAME_WIDTH, 320);ML.set(CV_CAP_PROP_FRAME_HEIGHT, 240);MR.set(CV_CAP_PROP_FRAME_WIDTH, 320);MR.set(CV_CAP_PROP_FRAME_HEIGHT, 240);Mat viewL, viewR;while (1){ML >> viewL;MR >> viewR;resize(viewR, viewR, Size(640, 480));resize(viewL, viewL, Size(640, 480));if (viewL.data && viewR.data){imshow("viewL", viewL);imshow("viewR", viewR);waitKey(3);}}return 0;
}

3，双目有一个USB接口

#include <opencv2\opencv.hpp>
#include <iostream>
#include <Windows.h>using namespace cv;
using namespace std;int main()
//int main()
{VideoCapture m_InputCapture(0);m_InputCapture.set(CV_CAP_PROP_FRAME_WIDTH, 1280);m_InputCapture.set(CV_CAP_PROP_FRAME_HEIGHT, 480);Mat view0, m_mView;while (!m_InputCapture.isOpened()){Sleep(2);cout << "cannot open the camera!" << endl;}for (;;){m_InputCapture >> view0;view0.copyTo(m_mView);Mat mLeftView = m_mView(cv::Rect(0, 0, 640, 480));Mat mRightView = m_mView(cv::Rect(640, 0, 640, 480));imshow("cameraR", mRightView);imshow("cameraL", mLeftView);waitKey(1);}return 0;
}
