vs2010+opencv 243 + 摄像头操作

环境: opencv使用的是2010下编译的库，版本号243

硬件: usb免驱摄像头或者笔记本自带的摄像头;

1：首先设置库和头文件

2：设置好后，就可以进行简单的读取操作了.

#include <cv.h> 
#include <cxcore.h>
#include <highgui.h>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/core/core.hpp>
int main()
{
    cv::VideoCapture cap;
    //cv::VideoCapture cap("bike.avi"); 可直接读取文件
    cv::Mat frame;
    if(!cap.open())
        return false;
    for(int i=;i<;i++)
        cap>>frame;

    int width = cap.get(CV_CAP_PROP_FRAME_WIDTH );//获取默认宽高
    int height = cap.get(CV_CAP_PROP_FRAME_HEIGHT );
    std::cout<< "width:" << width << std::endl;
    std::cout<< "height:" << height << std::endl;
    cap.set(CV_CAP_PROP_FRAME_WIDTH,);//设置宽高及其他参数，具体可参考set的说明
    cap.set(CV_CAP_PROP_FRAME_HEIGHT,);
    IplImage pFrame;  
    bool stop = false;
    while(!stop)
    {
        //cap>>frame;
        cv::waitKey();//帧率控制
        cap.read(frame);
        pFrame = frame;
        cvShowImage("video", &pFrame);//显示
        saveBmpImage(pFrame);
        if(cv::waitKey() >=)
            stop = true;
    }

    //memcpy(rgbData, pFrame.imageData, pFrame.imageSize);
    //rgbSize = pFrame.imageSize;

    //循环读取
    /*double fps;
    char string[50];  // 用于存放帧率的字符串
    double t = 0;
    IplImage pFrame;  
    bool stop = false;
    while(!stop)
    {
        //cap>>frame;
        t = (double)cv::getTickCount();
        cv::waitKey(25);//帧率控制
        cap.read(frame);
        pFrame = frame;
        cvShowImage("video", &pFrame);
        saveBmpImage(pFrame);
        if(cv::waitKey(25) >=0)
            stop = true;
    }*/
