Halcon
halcon代码 实现对瓶盖的数量检测
dev_close_window()
dev_open_window (0, 0, 512, 512, 'black', WindowHandle)
read_image (Image, 'D:/picture/IMG_20190427_200621.jpg')
*转换成灰度图（R，G，B）
decompose3 (Image, r, g, b)
*转换成HSV图
trans_from_rgb (r, g, b, h, s,v,'hsv')
*灰度提取 提取64以下
threshold (g, Regions, 0, 64)
*填充空隙
fill_up (Regions, RegionFillUp1)
*去噪
connection (RegionFillUp1, ConnectedRegions1)
*形态学开运算，对腐蚀结果进行膨胀，使区域更明显
opening_circle (ConnectedRegions1, RegionOpening, 30)
*选择区域 面积在10000以上
select_shape (RegionOpening, SelectedRegions, 'area', 'and', 10000, 1000000000)
*画轮廓
boundary (SelectedRegions, RegionBorder, 'inner')
*数数
