Design of Autonomous Navigation Control System of Seeder Based on FPGA

In order to improve the accuracy of the autonomous navigation control system of the seeder,improve the image processing speed of the navigation machine vision system,realize the real-time navigation function,reduce the time delay of data receiving and Parameter Solving,it introduced FPGA into the design of the navigation system,which effectively improves the navigation accuracy and efficiency of the seeder.Taking the tracking of the navigation center line of the seeder as an example,it verified the feasibility of using FPGA in the navigation system by the simulation of tracking error.The simulation results showed that it can obviously improve the accuracy of the navigation center line tracking of the navigation system by using FPGA feedback system,so as to improve the accuracy of the navigation system.
