Methods of movement for unmanned vehicles without satellite navigation systems

Abstract

A method for moving an unmanned vehicle without a satellite navigation system includes a vehicle-side control unit, a vehicle-side global positioning signal receiving unit, a calculation unit, an inertial measurement unit, an image acquisition unit, and a database. The vehicle-side global positioning signal receiving unit is signal-connected to the vehicle-side control unit; the calculation unit is signal-connected to the vehicle-side control unit; the inertial measurement unit is signal-connected to the calculation unit; the image acquisition unit is signal-connected to the calculation unit; and the database is signal-connected to the calculation unit. When the unmanned vehicle cannot receive satellite positioning signals due to external factors, the calculation unit calculates a correction signal by pairing images. The vehicle-side control unit then calculates subsequent control signals based on the correction signal, enabling the unmanned vehicle to complete its mission.
