摘要
针对传统叶面参数手工测量方法效率低、工作量大的缺点,设计了以嵌入式系统为核心,利用图像处理技术实现的数字式叶面测量仪。介绍测量仪的原理与结构,探讨由数字图像辨识叶面周长和面积等参数的具体算法,分析轮廓跟踪法和扫描线种子填充法相结合识别叶面轮廓的原理,提出了提高周长计算精度的改进算法。实验结果表明,该仪器测量速度快、效率高、操作方便,具有良好的实用价值。
Digital apparatus to measure the parameters of leaf surface, based on the application of digital image processing and embedded system, is designed in instead of traditional method by manual. The principle and structure of the apparatus are described in this paper. The recognition pattern algorithm dealing with perimeter and acreage of leaf surface is introduced. A better algorithm based on borderline track and scan filling methods, used to recognize leaf boundary, is discussed. The experimental results showed that the meter is high-efficient, real timing, convenient to operate and has broad application prospects.
