可拓工程方法在储粮害虫分类识别中的应用研究

Classification and recognition of stored-grain pests by using extension engineering method

利用图像识别储粮害虫过程中,需解决多种害虫的多特征参数和混和度大的分类识别问题。该文提出应用可拓工程方法,构造储粮害虫特征数据的标准物元矩阵与节域物元矩阵,计算待测粮虫与各类害虫的关联度,以关联度的大小对储粮害虫进行分类判别,程序计算结果表明,该方法可行有效。可拓工程方法应用在储粮害虫分类识别上有应用价值。

Using image technology to recognize the stored-grain insects, the classification and recognition of multi-characteristic parameters and multi-compound degree of various pests must be settled. This paper presents a new approach—extension engineering method—to solve this problem. This approach is based on constructing standard and extensional matter-element matrixes for various pests classification using matter-element and extension set, calculating the correlative degrees between the stored-grain pests to be recognized and various pests, and recognizing the pests according to magnitude of correlative degree. According to the calculated result, it is proved to be an effective and practical approach to classification and recognition of stored-grain pests.
