提出了一种利用图像实现颗粒粮食中异物的检测方法.该方法根据异物特征,提出了基于斑点分析的方法,一次成像2次处理,剔除比正常颗粒亮和暗的异物.设计包括输送系统、照明系统、成像系统、处理系统、结果存储和输出系统5个部分的异物检测系统,将粮食颗粒放到输送带上,在指定位置由成像系统获取图像,并将数据传入计算机进行分析处理,之后选用合适的算法进行图像处理.比较后发现,与Halcon库相比,Mil库设置的特征参数更多,使用者可以在较短时间内获取试验结果,并且Mil图像函数库的使用非常方便,故笔者选用Mil库提取绿豆颗粒中的异物杂质.利用Mil函数库开发的图像处理系统,把黑白斑点的2次提取处理,用一个函数实现,再通过数学形态学的运算和斑点分析,快速地提取杂质的大小和所在位置.该方法具有速度快、精确度高等优点,可以推广到其他领域加以应用.

A method to check impurities in food grain based on digital image processing is proposed in this study. According to the feature of the impurity, one image with twice processing is put forward based on blob analysis, which eliminates impurities that were brighter or darker than normal particles. With the image processing system developed by Matrox Imaging Library, black and white blobs are extracted for twice with one function, and then the size and the position of impurities are calculated quickly through mathematical morphologic and blob analysis. The method can be extended and applied in other fields due to its advantages of quick speed and high accuracy.
