提出了一种基于农田图像处理的视觉导航基准线的提取方法. 该方法首先使用加权平均法(2G-R-B)对原图像进行灰度化处理;采用改进最大化类间方差分割灰度图像;再用小面积法去噪;识别去噪后的图像的中心点,确定导航中心点位置. 基于中心点的分布规律,将图像中识别出的中心点进行筛选,得到有效的导航基准中心点,使用改进霍夫变换与最小二乘法相结合的方法提取导航基准线. 本文方法能够准确地识别和提取导航基准线,实验证明了该方法的有效性和实时性.
提齣瞭一種基于農田圖像處理的視覺導航基準線的提取方法. 該方法首先使用加權平均法(2G-R-B)對原圖像進行灰度化處理;採用改進最大化類間方差分割灰度圖像;再用小麵積法去譟;識彆去譟後的圖像的中心點,確定導航中心點位置. 基于中心點的分佈規律,將圖像中識彆齣的中心點進行篩選,得到有效的導航基準中心點,使用改進霍伕變換與最小二乘法相結閤的方法提取導航基準線. 本文方法能夠準確地識彆和提取導航基準線,實驗證明瞭該方法的有效性和實時性.

In this paper a method is presented to extracts visual navigation baseline based on the image processing of farmland.Firstly, the original image was gray scale processed using the weighted average method ( 2 G-R-B ) in this method.And then improved maximize between-class variance was used for gray scale image segmentation.Then the bi-nary image of the division was denoised with small area method.The center points were identified on denoised image, to determine the location of the center navigation.Based on the distribution of the center point, image obtained effective nav-igation center points after filtering.The navigation baseline was generated by using Hough transform.The proposed method and vertical projection method were used to handle different images of the crops.The conclusion is mentioned method is effective and has the real-time property.
