摘要
评价通过机器视觉的方法进行穗行数自动检测的可行性,提出一种基于边界标记和离散曲率的边缘算法确定行数,建立了检测模型。在扫描78幅不同玉米品种的果穗横断面图像的基础上进行检验。结果表明:试样玉米的穗行数为12~18行,检测的绝对误差为0.103行,相对误差率为0.66%,零误差率达到90%以上。实验证明检测算法真实可靠,机器视觉具有成本和速度上的优势,能够用于玉米穗行数的自动检测。
In order to exam feasibility of ear rows counting method by machine vision,a new method was raised.This method was based on edge marker and discrete curvature.78 digital images of 4 maize cultivars were scanned from 2 sides if maize fragment face.Based on this,it was found that the number was mostly 12-18,and the detecting absolute error was 0.103 and relative error rate was 0.66%.The accuracy rate was above 90%.Machine vision won the advantages of lowcost and high speed over manual or biochemical detecting...
