Coordinate correction system and method for unmanned equipment

The invention discloses a coordinate correction system for unmanned equipment. The coordinate correction system includes a hinged vehicle, and the hinged vehicle includes a front vehicle frame, a rear vehicle frame and a cab, and further includes a front-placed GPS antenna, a front-placed attitude sensor, a rear-placed GPS antenna, a rear-placed attitude sensor and a hinge angle sensor. The invention further discloses a coordinate correction method of the unmanned equipment. The coordinate correction method includes the following steps that a hinged vehicle coordinate point system is established; course angle correction of the hinged vehicle is conducted; coordinate correction of a front wheel unit of the hinged vehicle is conducted; and coordinate correction of a rear wheel unit of the hinged vehicle is conducted. According to the coordinate correction system and method for the unmanned equipment, based on information of double-antenna GPS and the attitude sensors, the measurement coordinates of the unmanned
