Halcon找线

如何找到黑白边界线

read_image (Image, 'C:/Users/Lenovo/Desktop/11.png')
rgb1_to_gray (Image, GrayImage)
threshold (GrayImage, Regions, 105, 255)
connection (Regions, Connection)
opening_rectangle1 (Connection, RegionOpening, 10, 10)
select_shape (RegionOpening, SelectedRegions, 'area', 'and',1000, 130000)
fill_up (SelectedRegions, RegionFillUp)
inner_rectangle1 (RegionFillUp, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
get_image_size (GrayImage, Width, Height)
gen_region_line (RegionLines, Row1, 0, Row1, 1095)

threshold (GrayImage, Regions, 47, 255)
效果会好点

不是很明白要找哪条线，最好可以标出来或者放多点图片
