本文实例为大家分享了opencv摄像头捕获识别颜色的具体代码，供大家参考，具体内容如下

#include "highgui.h" #include "iostream"using namespace std; int main() { CvCapture* pCap = cvCreateCameraCapture(1 );//这里-1也可以，不过我的电脑装的有CyberLink YouCam软件， int flag=0; //OpenCV会默认调用该摄像头，而不调用系统的驱动 IplImage* frame =NULL; if (cvCreateCameraCapture == NULL) { return(0); } cvNamedWindow("Camera",CV_WINDOW_FULLSCREEN); while ((frame = cvQueryFrame(pCap)) != 0 && cvWaitKey(20) != 27) { frame = cvQueryFrame(pCap); //cout<<frame->width<<" "<<frame->height<<endl; flag=0; for(int x=0;x<frame->height;x++) { for(int y=0;y<frame->width*3;y++) { //CV_IMAGE_ELEM(frame,uchar,x,y)=255; if( ((uchar*)(frame->imageData+x*frame->widthStep))[y*frame->nChannels+0]<30 //b &&((uchar*)(frame->imageData + x*frame->widthStep))[y*frame->nChannels + 1]<30 //g &&((uchar*)(frame->imageData + x*frame->widthStep))[y*frame->nChannels + 2]>150) //r flag++; } } cout<<flag<<endl; if(flag>70000) cout<<"red"; else cvShowImage("Camera",frame); } aaa: cvReleaseCapture(&pCap); cvDestroyWindow("Camera"); system("pause"); return (0); }
