  生成水产鱼饲料颗粒时，生产产品的尺寸较为重要。因利用机器持续设置的生产方法无法生成持续一致的颗粒，有需要对尺寸大小进行控制。喂食鱼的饲料颗粒尺寸不均一，不一定如所愿尺寸，水产养殖不希望出现此类情况。该文章推荐了一种图像分析方法，用于自动监控颗粒尺寸，称之为颗粒几何学，此处所用方法是基于数学形态学开放操作。所推荐的方法，无需对图像目标进行分区。结果表明有可能从堆满不规则颗粒的图像中提取通用尺寸分布信息，做为一个区域有代表性的颗粒的长度和直径。详细产品信息请看链接，全文下载链接Image Analysis of Pellet Size.PDF。

Image Analysis of Pellet Size for a Control System in Industrial Feed Production

Abstract

When producing aquaculture fish feed pellets, the size of the output product is of immense importance. As the production method cannot produce pellets of constant and uniform size using constant machine settings, there is a demand for size control. Fish fed with feed pellets of improper size are prone to not grow as expected,  which is undesirable to the aquaculture industry. In this paper an image analysis method is proposed for automatic size-monitoring of pellets. This is called granulometry and the method used here is based on the mathematical morphological opening operation. In the proposed method, no image object segmentation is needed. The results show that it is possible to extract a general size distribution from an image of piled disordered pellets representing both length and diameter of the pellets in combination as an area.
