悬铃木方翅网蝽是一种寡食性入侵害虫,主要为害城市绿化树种悬铃木,近年来传播蔓延很快。对其进行远程识别和监测,对了解其传播规律和制定绿色防控措施很重要。本文利用图像获取和分析技术对该害虫进行外部几何形态特征的提取研究。结果表明,扫描时分辨率越高,图像越清晰,但耗时也越长。在分辨率1200dpi时,能够观察到悬铃木方翅网蝽翅缘和侧背板的锯齿状结构,且各参数极差最小。在此分辨率下,除周长和紧凑性外,其他各参数在悬铃木方翅网蝽雌雄个体间的差异均达到显著水平,可以作为区分不同性别个体的参数标准。
Platycladus Orientalis is an omnivorous insects pests, mainly for urban afforestation trees Platanus, spread rapidly in recent years. It is important to identify and monitor them remotely, to understand their laws of transmission and to develop green controls. In this paper, we use image acquisition and analysis techniques to extract the external morphological features of the pest. The results show that the higher the resolution of the scan, the clearer the image, but the longer it takes. At 1200dpi resolution, the zigzag structure of the wing edge and the back plate of Platycladus orientalis can be observed with the minimum difference of each parameter. At this resolution, in addition to the perimeter and compactness, the other parameters in the male and female male Plagiolus were significantly different, can be used as a parameter to distinguish between different sex individuals.
