halcon-distance_pc計算點和輪廓之間的距離

  

在HDevelop中

dev_close_window ()
dev_update_off()
read_image (Image9, 'D:/bb/tu/9.jpg')
rgb1_to_gray (Image9, GrayImage)

threshold (GrayImage, Region, 200, 255)
connection (Region, ConnectedRegions)
select_obj (ConnectedRegions, ObjectSelected, 2)
gen_contour_region_xld (ObjectSelected, Contours, 'border')
*根據區域創建XLD輪廓

Row:=[10,15]
Column:=[10,15]

distance_pc (Contours, Row, Column, DistanceMin, DistanceMax)
*計算點和輪廓之間的距離
*計算一個或多個點與單個輪廓之間的距離
*參數1：輸入xld輪廓
*參數2：點的行坐標
*參數3：點的列坐標
*參數4：返回點與輪廓之間的最小距離
*參數5：返回點與輪廓之間的最大距離

gen_region_points (Region1, Row, Column)
*創建點區域

get_image_size (Image9, Width, Height)
dev_open_window(10,10,Width, Height,'black',WindowHandle)
dev_display(Region1)
dev_display(Contours)
