摘要: 烟草是一种特殊农作物,烟草的提取对其信息统计起着重要作用。针对烟草单株提取难的问题,提出了一种结合多特征和超像素的无人机影像烟草精细提取方法。首先利用简单线性迭代聚类 (Simple Linear Iterative Clustering, SLIC)算法对影像进行超像素分割;然后统计超像素的平均值、亮度、长宽比、形状指数、红绿蓝波段值和自定义植被指数;接着通过对超像素特征组合和特征阈值选取来实现烟草的精细提取;最后对提取信息进行统计和分析。实验结果表明:该方法能有效地提取烟草株树,准确度分别为99%和98.6%。利用该方法,在计算烟草产量方面供了有效参考,节省了大部分的人力财力。 关键词: 烟草;  无人机影像;  简单线性迭代聚类;  超像素分割;  信息提取     Abstract: Tobacco is a special crop and the extraction of tobacco plays an important role in its statistics. Aiming at the difficulty of extracting tobacco plants, a tobacco fine extraction method in Unmanned Aerial Vehicle image combined with multi-features and superpixels is proposed. Firstly, the image is segmented by simple linear iterative clustering algorithm; secondly, the Mean value, Brightness, Length/Width, Shape index, Red, Green and Blue band value and custom vegetation index of super pixel are counted; thirdly, fine extraction of tobacco by superpixel features combination and features threshold selection; finally, the extracted information are satisficed and analyzed. The experimental results shown that the method can effectively extract tobacco trees, and the accuracy is 99% and 98.6%, respectively. Using this method, it provides an effective reference in calculating tobacco production, saving most of the human and financial resources.
