opencv2.4.10+VS2013,可以打开摄像头，但是不显示图像，只显示灰色

[迷上微笑]

#include <opencv2\opencv.hpp>
#include<stdio.h>
using namespace std;
int main(int argc, char** argv)
{
//声明IplImage指针
IplImage* pFrame = NULL;

//获取摄像头
CvCapture* pCapture = cvCaptureFromCAM(-1);// cvCreateCameraCapture(-1);

//创建窗口
cvNamedWindow("Video", 1);

//显示视屏
while (1)
{
pFrame = cvQueryFrame(pCapture);
if (!pFrame)break;
cvShowImage("Video", pFrame);
char c = cvWaitKey(33);
if (c == 27)break;
}
cvReleaseCapture(&pCapture);
cvDestroyWindow("Video");
return 0;

}

建议先编译链接调试OpenCV自带的相关例子代码。

#include <opencv2\opencv.hpp> #include<stdio.h> using namespace std; int main(int argc, char** argv) { //声明IplImage指针 IplImage* pFrame = NULL; //获取摄像头 CvCapture* pCapture = cvCaptureFromCAM(0);// cvCreateCameraCapture(0); cvWaitKey(200); //创建窗口 cvNamedWindow("Video", 1); //显示视屏 while (1) { pFrame = cvQueryFrame(pCapture); if (!pFrame)break; cvShowImage("Video", pFrame); char c = cvWaitKey(33); if (c == 27)break; } cvReleaseCapture(&pCapture); cvDestroyWindow("Video"); return 0; } 这样是可以解决这个问题的，请LZ参考
