摘　　要：为及时准确地监测预报农田害虫的发生情况,采用了图像处理的方法对诱集到的害虫进行识别.选用HSI彩色模型空间,确定了红、黄、绿、青、兰、紫、黑7种主要颜色,每种颜色分别提取了5种形态特征,包括新提出的描述颜色的一个重要特征———圆度的新定义.采用VC++6 0语言编制了程序,对绿刺蛾和红缘灯蛾进行了色彩特征的提取,识别率达到85 7%.结果表明,所提取的特征有利于识别害虫.Pests lured through image process are identified in order to monitor and forecast agricultural pests' situation in time. Selecting HSI color model space, seven main colors are determined,such as red, yellow, green, cyan, blue, purple and black. To each color five morphologic features such as area, perimeter, width, height, roundness are extracted,and a new definition of roundness as a main feature on describing colors is put forward. By programming with VC++ 6.0, color features to Parasa consocia and Amsacta lactinea are extracted. The rate of recognition is up to 85.7%. Results show that extracted color features are advantageous to recognizing agricultural pests.
