Intelligent charging method and system for unmanned vehicle which can allow multiple unmanned vehicles to automatically return to the ground station for charging after performing tasks

The present invention discloses an intelligent charging method and system for an unmanned vehicle. The intelligent charging system for unmanned vehicle includes an unmanned vehicle, a charging station, a second wireless communication module, a first image capturing device, and an information processing unit. The unmanned vehicle includes a power device, a flight control module and a first wireless communication module. The charging station includes a platform and a power supply device, wherein each platform is set with coordinate parameter data. The first image capturing device is disposed above the area close to the center point and can capture continuous image of the area to obtain the imaging as the area image. The information processing unit is used to perform image recognition processing on the currently captured area image so as to calculate the vacancy/occupancy information of each platform. When the unmanned vehicle is ready to land for charging, the information processing unit will transmit the coord
