摘要
采用大数据技术和隐马尔科夫模型,对拖拉机轨迹预测进行了研究。为了高效、精准地对拖拉机进行实时定位,在5G节点信号强度矢量进行定位的基础上,采用隐马尔科夫的轨迹对拖拉机定位信息进行精确定位。实验结果表明:拖拉机轨迹预测的准确度在0.9左右,符合设计需求。系统具有较高的准确度,对拖拉机定位和轨迹预测具有一定的参考意义。
It studied the tractor trajectory prediction by using big data technology and Hidden Markov.In order to locate the tractor in real time efficiently and accurately,it used the hidden Markov trajectory to accurately locate the tractor positioning information based on the 5G node signal strength vector.The experimental results show that the accuracy of tractor trajectory prediction is about 0.9,which meets the design requirements.It proves that the system has high accuracy,which has certain reference significance for tractor positioning and trajectory prediction.
