NAVIGATION METHOD FOR UNMANNED VEHICLE IN FARMLAND OR WOODLAND

摘要

A navigation method for an unmanned vehicle in farmland or woodland is provided, comprising: (a) planning travel routes for an unmanned vehicle in farmland or woodland, wherein the travel routes do not intersect or overlap; and laying continuous metal wires on the ground along the travel routes; (b) disposing N horizontally evenly arranged metal probes on the vehicle head of the unmanned vehicle, wherein N is a positive integer greater than or equal to 2; (c) placing the unmanned vehicle on a travel route, and calculating a vector sum of vectors sensed by the N metal probes; and (d) controlling the unmanned vehicle to move forward along the direction of the calculated vector sum. The present invention provides the navigation method for the unmanned vehicle in farmland or woodland to solve the prior-art problem in which it has not been possible to provide accurate navigation for an unmanned vehicle operating in fields, providing a guide for the unmanned vehicle to move accurately in fields and improving the degree of automation.
