| 摘 要： | 基于图像处理技术提出了一种倒伏小麦的检测方法.首先,对田间倒伏小麦进行图像采集,进而探讨了基于颜色特征的图像识别方法.通过对彩色图像灰度化以及灰度反色处理后,再选取中值滤波法去除噪声,最后用高斯-拉普拉斯算子边缘检测方法提取图像边缘,得出倒伏小麦与正常小麦之间的高度差,据此控制收割机割台的高度.此方法可降低倒伏小麦造成的颗粒损失,提高农业生产机械的自动化水平,降低劳动者的劳动强度.

| Abstract: | This paper states a metrical method for the felled wheat based on the image processing.Through taking pictures of the felled wheat on field.this essay discussed the discriminating ways according to color characters.Then by changing the color picture into the gray picture and filtering the noises,we pick up the picture edge through the Gauss-Lap lace's arithmetic operators.This process can help educe the altitude difference between the felled wheat and the natural wheat,which can be used to control the altit... |
