The invention relates to a reference detecting device of an automatic drilling and riveting system of airplane components and a detecting method thereof. The detecting method comprises the following steps of: acquiring information of a reference profile by a 2D laser displacement sensor and a distance sensor, establishing a parameter space of a reference hole center coordinate by applying a least square method, then realizing transformation from a reference hole boundary space domain to the reference hole center coordinate by applying generalized Hough transformation, fitting and calculating a reference center position, and realizing detection of an actual position of the reference, thus realizing determination of the actual position for the processing reference of the automatic drilling and riveting system so as to determine the deviation between the theoretical position and the actual position of the reference. The positions of points to be preprocessed on a product are compensated and corrected, so that th
