halcon-prewitt_amp计算边缘

在HDevelop中

dev_close_window ()
read_image (Image, 'D:/bb/tu/1.jpg')
rgb1_to_gray (Image, GrayImage)

prewitt_amp (GrayImage, ImageEdgeAmp)
*计算边缘
*参数2：输出图像


get_image_size (GrayImage, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(ImageEdgeAmp)

在QtCreator中

HObject  ho_Image, ho_GrayImage, ho_ImageEdgeAmp;
  HTuple  hv_Width, hv_Height, hv_WindowHandle;

ReadImage(&ho_Image, "D:/bb/tu/1.jpg");
  Rgb1ToGray(ho_Image, &ho_GrayImage);

  PrewittAmp(ho_GrayImage, &ho_ImageEdgeAmp);
  //计算边缘
  //参数2：输出图像


  GetImageSize(ho_GrayImage, &hv_Width, &hv_Height);
  SetWindowAttr("background_color","black");
  OpenWindow(10,10,hv_Width,hv_Height,0,"visible","",&hv_WindowHandle);
  HDevWindowStack::Push(hv_WindowHandle);
  if (HDevWindowStack::IsOpen())
    DispObj(ho_ImageEdgeAmp, HDevWindowStack::GetActive());
