OpenCV 擷取Webcam

轉灰階

IplImage * GRAY = 0;
GRAY = cvCreateImage(cvSize(frame1->width,frame1->height),IPL_DEPTH_8U,1);
cvCvtColor(frame1, GRAY, CV_RGB2GRAY);
cvCvtColor(GRAY, frame1, CV_GRAY2RGB);
cvReleaseImage(&GRAY);

啟動WebCam，並指定handle給 Panel

int ncams = cvcamGetCamerasCount();
int width=640;
int height=480;
Panel1->Width = width;
Panel1->Height = height;

HWND hwnd = Panel1->Handle;

cvcamSetProperty(0, CVCAM_PROP_ENABLE, CVCAMTRUE);
cvcamSetProperty(0, CVCAM_PROP_CALLBACK,CaptureCallback);
cvcamSetProperty(0, CVCAM_PROP_WINDOW, &hwnd);
cvcamSetProperty(0,CVCAM_RNDWIDTH,&width);
cvcamSetProperty(0,CVCAM_RNDHEIGHT,&height);


cvcamGetProperty(0,CVCAM_CAMERAPROPS,NULL); // 開啟webcam設定介面

cvcamInit();
cvcamStart();

關閉WebCam

cvcamStop();

cvcamExit();
