halcon-edges_image计算边缘

 

 

在HDevelop中

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

edges_image (GrayImage, ImaAmp, ImaDir, 'canny', 1, 'nms', 20, 40)
*计算边缘
*参数1:输入图像
*参数2:输出图像
*参数3:图像边缘方向
*参数4:边缘算子
*       'canny'
*       'deriche1'
*       'deriche1_int4'
*       'deriche2'
*       'deriche2_int4'
*       'lanser1'
*       'lanser2', 'mshen', 'shen', 'sobel_fast'
*参数5:迭代次数,小的值导致强平滑,但是更少的细节(canny算子相反)
*参数6:非最大抑制(设置为none,表示不需要使用该值)
*参数7:低阈值(如果不需要阈值设置,则为负值)
*参数8:高阈值(如果不需要阈值设置,则为负值),高阈值一般是低阈值的1.5-2倍



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

dev_open_window(10,10,Width, Height,'black',WindowHandle1)
dev_display(GrayImage)

 

 

在QtCreator中

  HObject  ho_Image, ho_GrayImage, ho_ImaAmp, ho_ImaDir;
  HTuple  hv_Width, hv_Height, hv_WindowHandle;
  HTuple  hv_WindowHandle1;
  ReadImage(&ho_Image, "D:/bb/tu/1.jpg");
  Rgb1ToGray(ho_Image, &ho_GrayImage);

  EdgesImage(ho_GrayImage, &ho_ImaAmp, &ho_ImaDir, "canny", 1, "nms", 20, 40);
