检测保险丝有没有断开

 

 

 思路就是，没有断开的保险是3个区域，如果断开了就没有三个区域

read_image (Image, '2')
get_image_size (Image, Width, Height)
dev_close_window ()
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)

closing_rectangle1 (RegionUnion, RegionClosing, 50, 50)
smallest_rectangle1 (RegionClosing, Row1, Column1, Row2, Column2)
gen_rectangle1 (Rectangle, Row1, Column1, Row2, Column2)
reduce_domain (Image, Rectangle, ImageReduced)
