halcon-smallest_circle獲取區域的最小外接圓數據

 

 

在HDevelop中

read_image (Image, 'D:/bb/tu/5.jpg')
rgb1_to_gray(Image,Image1)
threshold (Image1, Region,[75] , [90])

smallest_circle (Region, Row, Column, Radius)
*獲取區域最小外接圓數據
*參數1：輸入給定區域
*參數2：輸出中心行坐標-y坐標
*參數3：輸出中心列坐標-x坐標
*參數4：輸出外接圓半徑

gen_circle (Circle, Row, Column, Radius)
*創建一個圓區域

get_image_size (Image1, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Region)
dev_open_window(10,100,Width, Height,'black',WindowHandle1)
dev_display(Circle)
