以武育粳3号为试验品种,用自制计算机视觉系统,拍摄成熟期水稻群体图像,应用分形理论分析水稻群体图像的分形特征,在此基础上提取了图像的差分计盒维数和多重分形曲线;并进一步分析得出水稻单位面积产量与水稻图像分形维数具有线性相关关系,最后建立水稻单位面积产量模型,模型精度为92.57%。
水田驱动叶轮轮叶下土壤流动特性与动力性能研究(Soil Flow Rule and Dynamic Performance under a Paddy-field Wheel Lug)
水田驱动叶轮 轮叶 土壤流动 动力性能
2010/12/28
在自制的小土槽试验装置上,进行了水田驱动叶轮轮叶下土壤流动的拍摄和轮叶上土壤反力的测试。在研究轮叶下土壤流动轨迹、流动模式和流动区大小变化规律的基础上,分析了轮叶产生的推进力和支承力,驱动效率的变化规律及其与土壤流动之间的关系。深入分析了有较大陷深和作旋轮线运动的轮叶的驱动效率较低的原因。
超声波传感器评定水田激光平地机水平控制系统性能(Evaluation of Leveling Performance for Laser-controlled Leveling Machine in Paddy Field Based on Ultrasonic Sensors)
