基于图像处理技术对植物叶片面积测量

Measurement of plant leaf area based on image processing technology

针对叶片面积测量,设计并实现一种基于图像处理对叶片面积进行测量的方法。利用CDD摄像机获取植物叶片图像,对采集的植物叶片图像进行图像分割和边缘检测,通过对比Sobel、Robert、Prewitt和Canny算子选取理想图片,再利用形态学处理对缝隙和噪音进行平滑处理,最后通过像素统计法获得测量面积,与真实面积进行相关性分析。该方法可以准确、便捷地测量植物叶片的面积。

Aiming at the measurement of leaf area,a method for measuring leaf area based on image processing is designed and implemented.Use the CDD camera to obtain plant leaf images,perform image segmentation and edge detection on the collected plant leaf images,select ideal pictures by comparing Sobel,Robert,Prewitt and Canny operators,and then use morphological processing to smooth the gaps and noises,and finally The measured area is obtained by the pixel statistics method,and the correlation analysis is carried out with the real area.This method can accurately and conveniently measure the area of plant leaves.
