摘要
提供了采用数字图像处理方法快速计算植物虫损叶片面积的方法,对叶片图像进行图像采集、预处理以及几何校正,提取叶片轮廓并填充后,去除叶柄求得虫损叶片面积及虫损率。此方法简单易行,适合多种形状叶片,同时适用于非虫损叶片面积的测量。
By using image processing,in this paper,a fast way to measure damaged plant leaf area was proposed.Firstly,after image acquisition,pretreatment and geometric rectification,then extracting the outline and filling it and finally,the petiole was removed,the area and damage rate are acquired,which was suitable for different forms of leaves and the area calculation of leaf without damage.
