創(chuàng)建新函數(shù)：將多個算子封裝成一個新的函數(shù)

mean_image (Image, ImageMean, mean_width, mean_height)
reduce_domain (ImageMean, Rectangle, ImageReduced)
threshold (ImageReduced, Region, 78, 255)
area_center (Region, Area, Row, Column)

也可以在菜單欄中創(chuàng)建

定義新函數(shù)名稱

點擊圖中“參數(shù)”，刪減參數(shù)，把不用的參數(shù)刪掉即可

生成的新函數(shù)

選中函數(shù)右鍵鼠標 選擇顯示函數(shù)可以查看封裝的Halcon算子

比如不需要Area參數(shù)名 將其移除后點擊應用

參數(shù)介紹：

圖標參數(shù)：一般Region、Image、XLD等都屬于圖標參數(shù)。

控制參數(shù)：一般數(shù)據(jù)、字符串都屬于控制參數(shù)。

以上Halcon函數(shù)介紹完畢。
