The invention relates to an unmanned aerial vehicle laser charging positioning method and system based on laser navigation, in particular to the technical field of laser, and aims to create a laser signal network area and a three-dimensional virtual space to improve the safety and management efficiency of a charging station. The position and the attitude of the unmanned aerial vehicle are obtained through the time difference and the relative orientation relation between the laser receiver and any three laser transmitters, and the optical band-pass filter allows signals in the laser signal frequency band range to pass through and prevents signals beyond the laser signal frequency band range, so that the possibility of signal attenuation and distortion is reduced; according to the method, the definition and reliability of signals are improved, an optimal charging simulation path is planned in a three-dimensional virtual space by using an A * algorithm and collision is avoided, the optimal charging simulation path is received through a wireless communication link and is fed back to the position and attitude of the unmanned aerial vehicle for adjustment, and the optimal charging simulation path is realized. And the charging abnormal state is judged and readjusted, so that the safety and stability of the charging process are ensured.
