The invention discloses a multi-functional unmanned aerial vehicle intelligent take off and land station system which comprises a visual coarse positioning module. The visual coarse positioning module comprises an instation controller which is connected with an image acquisition device. The image acquisition device is arranged in a take off and land station and is used for acquiring an unmanned aerial vehicle image in real time, and transmitting the image to the instation controller. An airborne controller controls the landing height of an unmanned aerial vehicle and the head direction of the unmanned aerial vehicle. The system further comprises a fine positioning module which comprises a support frame which is used for carrying the unmanned aerial vehicle. Grooves which match rotors of the unmanned aerial vehicle are arranged on the support frame. A notch is arranged on the side, which contacts the unmanned aerial vehicle support frame, of each groove. The notches are used for supporting and fixing the unmanned aerial vehicle. The system further comprises a self-sustaining module which is used for receiving the electric quantity information and the battery position information, which are transmitted from the airborne controller, of an unmanned aerial vehicle battery compartment, and charging the unmanned aerial vehicle battery compartment lower than or equal to the preset electric quantity information to realize self-sustaining of the unmanned aerial vehicle.
