The invention discloses an unmanned helicopter blade dynamic balance calibration system and calibration method. The unmanned helicopter blade dynamic balance calibration system comprises an unmanned helicopter blade mechanism, a laser range finder and a ground control station. According to the unmanned helicopter blade dynamic balance calibration system and calibration method disclosed by the invention, dynamic data of blades are acquired through the laser range finder, so that the data acquisition is safer and the accuracy is high; compared with a stroboscope method, the system is more economical and simple to operate; and after the collected data are coded, the currently collected data can be displayed in real time, and by means of an expert system of a ground control station, the qualification can be analyzed and judged, and the adjustment length of a paddle variable-pitch pull rod can be accurately indicated.
