The invention provides a calibration method of an unmanned aerial vehicle sensor, which comprises the steps that a calibration instruction is sent through an APP, and a system obtains the enabling state of a current calibration switch; according to the enabling state of the current calibration switch, the unmanned aerial vehicle is processed according to a preset first rule, and the calibration enabling state of the unmanned aerial vehicle is obtained; when the calibration enabling state of the unmanned aerial vehicle is true, a calibration instruction is exeucted, sensor measurement values of the unmanned aerial vehicle are collected according to a preset second rule, the measurement values are calculated by using a damping least square method, and an optimal calibration parameter of the unmanned aerial vehicle sensor is solved; and the unmanned aerial vehicle sensor is calibrated according to the solved optimal calibration parameter of the unmanned aerial vehicle sensor. The problems are solved that an unmanned aerial vehicle sensor calibration method in the prior art is high in dependence on a calibration environment and low in precision.
