採用Basler4.0SDK編寫，利用Event機制在回撥函式中生成灰度影象
回撥函式中影象生成程式碼，利用CCD中獲取的無符號字元型陣列轉變成
Mat型別

Mat grab( siz, CV_8UC1, ptrGrabResult->GetBuffer(), siz.width*1 ); namedWindow( "test" ); imshow( "test", grab ); cvWaitKey(300);

IplImage* src = cvCreateImage( siz,IPL_DEPTH_8U, 1 ); cvSetData( src, ptrGrabResult->GetBuffer(), siz.width*1 ); cvNamedWindow("test"); cvShowImage( "test", src );
