| 摘 要： | DGPS定位系统在外界干扰的作用下会导致定位信息中含有野值。这些野值对插秧机的精准控制有很大的影响,必须对DGPS的野值进行处理。为此,提出了一种基于插秧机运动学模型的DGPS野值在线剔除方法。该方法根据插秧机的运动模型设定野值判定阈值,然后采用基于插秧机运动学模型进行推算的估计值对野值进行替换。试验结果表明该方法能够很好地剔除DGPS位置信息中的野值。

| Abstract: | The locating information of DGPS contains outliers in the disturbed environment.These outliers that must be treated,has a great influence on the control precision of transplanter.The thesis proposed a method to treat the ouliers on-line based on the kinematics model of transplanter.The method get the outliers threshold by the movement model of trans-planter.And then the outliers is replaced by the estimated value.The experimental results show that the method can e-liminate the outliers better in DGPS location information. |
