Study on Automatic Guiding of Agricultural Vehicle by Using Inner Sensors (Part 3) ——Position detecting system in agricultural environment

A position detecting system for agricultural vehicle is introduced. The angular velocities and velocity of the vehicle are detected by inner sensors. The direction angular and the moving distance are obtained through integrating with detecting values and the direction can also be gotten from the position calculating model. On account of the influence of pitching and rolling three angular velometers are used so that a three right angular coordinate system is built and the angular velocities can be modified. This position detecting system is of good detecting accuracy.
