halcon-distance_cc計算兩個輪廓之間最小和最大的距離

 

 

在HDevelop中

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

threshold (GrayImage, Region, 200, 255)
connection (Region, ConnectedRegions)
select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 15400, 15500)
smallest_rectangle1 (SelectedRegions, Row1, Column1, Row2, Column2)
*返回最小外接正矩形數據
gen_rectangle1 (Rectangle, Row1+10, Column1-10, Row2-10, Column2+10)
*創建一個平行於坐標軸的矩形區域
*說明：行往里縮小的目的：亞像素邊緣時可以去掉上下的邊
reduce_domain (GrayImage, Rectangle, ImageReduced)
**獲取區域圖像
edges_sub_pix (ImageReduced, Edges, 'canny', 1, 20, 40)
*亞像素邊緣

sort_contours_xld (Edges, SortedContours, 'upper_left', 'true', 'column')

select_obj (Edges, ObjectSelected, 1)
select_obj (Edges, ObjectSelected1, 2)

get_contour_xld (ObjectSelected, Row, Col)
get_contour_xld (ObjectSelected1, Row3, Col1)

distance_cc (ObjectSelected, ObjectSelected1, 'point_to_point', DistanceMin, DistanceMax)
*計算兩個輪廓之間最小和最大的距離
*參數1：第一個輪廓
*參數2：第二個輸入輪廓
*參數3：距離計算模式
*      'point_to_point'     確定輪廓線之間的最小和最大距離
*      'point_to_segment'   輪廓線段之間的實際最小距離
*參數4：返回兩個輪廓之間的最小距離
*參數5：兩個輪廓之間的最大距離
