| 摘 要： | 针对目前联合收割机在收获过程中，行走速度，喂入量都是人工调节．调节不当时，便会造成脱不净，夹带，脱粒损失大等情况，其主要因素是喂入量没有根据作物空间密度得到实时调整．本文从研究水稻冠层密度分布出发，提出了一种基于RGB彩色模型的水稻冠层密度分布图像的检测方法，对2R＋G颜色特征量图像采用迭代法自动选取阈值将谷、叶从背景中分割出来；建立冠层图像像素与水稻喂入量的定量关系．为联合收割机实时调整喂入量提供一种可行方案．对改进联合收割机的收获质量有很大的参考价值．

| Abstract: | The walking speed and feeding of crop of the present combine are controlled manually.Improper regulation may lead to partially threshing,entrainment or threshing large losses,as a result of failure in real-time adjustment of feeding of crop according to spatial density of rice.With the study of the rice canopy density distribution,a detecting method based on its RGB color model is proposed in this paper.Threshold images are automatically selected by iterative method to segment cereal and leaves from the bac... |
