halcon-sobel_dir计算边缘

 

 

在HDevelop中

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

sobel_dir (GrayImage, EdgeAmplitude, EdgeDirection, 'sum_abs', 3)
*计算边缘
*参数2：输出图像
*参数3：输出边缘方向图像
*参数4：掩码类型
*参数5：掩码大小


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

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

 

 

在QtCreator中

  //计算边缘
  //参数2：输出图像
  //参数3：输出边缘方向图像
  //参数4：掩码类型
  //参数5：掩码大小
