摘 要: 研究了蜻蜓图像的自动识别技术,构建了基于浏览器/服务器(B/S)架构的蜻蜓自动识别系统。通过分析蜻蜓彩色图像的颜色和灰度特征,利用灰度阀值分割法去除图像背景,然后计算蜻蜓的几何不变矩纹理特征,将结果与建立的蜻蜓样本数据库数据进行相似度计算,确定蜻蜓种类。结果表明,该系统能够获得较好的识别效果,为昆虫识别的研究提供新的手段。 The automatic recognition technology of dragonfly images was studied and the dragonfly automatic recognition system based on browser/server(B/S) structure was constructed in this paper.Through analyzing the color and gray characteristics of dragonfly color image,the grayscale threshold segmentation method was used to eliminate image background,and then the geometry moment invariants texture characteristics of dragonfly was calculated,and last the similarity calculation was proceed between the calculated result and the data of dragonfly sample database to determine the dragonfly species.The results showed that the system can achieve good recognition effect and provide new method for insect recognition research.
