1. A near-field sensing information transmission and pairing system for air-land unmanned vehicles, comprising:
an unmanned aviation vehicle, comprising:
a detection module, wherein when the unmanned aviation vehicle is moving along a forward route, the detection module is configured to enable at least one sensor and an image recognition unit to continuously sense at least one obstacle or a traffic control feature located on ground of the forward route;
a transceiver module, connected to the detection module, wherein when sensing presence of the obstacle or the traffic control feature, the transceiver module generates and transmits a re-routing signal comprising at least one obstacle coordinate based on a position of the obstacle or the traffic control feature, and receives the forward route and an alternative route; and
a flight module, connected to the transceiver module and configured to control the unmanned aviation vehicle to fly along the forward route, wherein when receiving the alternative route, the flight module controls the unmanned aviation vehicle to fly along the alternative route, instead of the forward route; and
an unmanned ground vehicle, configured to perform information transmission with the unmanned aviation vehicle through wireless communication pairing, wherein when a plane distance between the unmanned aviation vehicle and the unmanned ground vehicle satisfies an interval distance, the unmanned ground vehicle moves along the forward route, when the plane distance is lower than the interval distance, the unmanned ground vehicle stops moving, the unmanned ground vehicle comprises:
a positioning module, configured to continuously obtain a current coordinate from a positioning system when the unmanned ground vehicle is moving along the forward route;
a map module, configured to store map information, wherein the map information comprises geographic information and the forward route which is from the current coordinate to a destination coordinate;
a transmission module, connected to the positioning module and the map module, and configured to transmit the forward route to the unmanned aviation vehicle in initial to make the unmanned aviation vehicle move along the forward route, and receive the re-routing signal transmitted from the unmanned aviation vehicle; and
a calculation module, connected to the positioning module, the map module, and the transmission module, and wherein when receiving the re-routing signal, the calculation module loads the map information from the map module, and calculates the alternative route for replacing the forward route based on the current coordinate, the obstacle coordinate and the destination coordinate, and transmits the alternative route to the unmanned aviation vehicle through the transmission module.
