基于多传感器融合的拖拉机自动导航技术

Precise Seeder Automatic Navigation Technology Bases on the Fustion between GPS and Sensors

GPS是农业自动导航车辆获取导航信息的一种主要方式,其任务是获取拖拉机的绝对位置信息,而多传感器融合可以在GPS提供的绝对位置信号丢失时为拖拉机提供位置、姿态和航向信息,进行准确的定位。为此,介绍了GPS以及多传感器融合在拖拉机自动导航中的应用现状,指出GPS及多传感器在自动导航方面的优势和存在的问题,分析了GPS和多传感器融合的导航方式在未来精细农业领域的巨大作用。

GPS is a major way of automatic navigation of agricultural vehicle to get navigation information,Its main task is to obtain the absolute position information of the tractor,The multi-sensor fusion can provide position,attitude and heading information for the tractor and Provide accurate location information when the GPS absolute position signal is lost.,Therefore,this paper introduces the application situation of GPS and multi-sensor fusion in tractor automatic navigation,makes people recognize the advantages and problems of GPS and multi-sensor fusion navigation,and the role of GPS navigation and multi-sensor fusion in the future field of precision agriculture.
