The invention provides an aircraft axis boresight system and method. The boresight method comprises the steps that laser emitted by a laser emitter is filtered; the laser axis fixing device is used for splitting the laser beam; the two area-array cameras are used for imaging reflected and transmitted laser spots respectively; and the calculation module calculates the spatial centroid coordinates of the reflected and transmitted laser spot images and obtains a boresight result. The laser emitted by the laser assembly has good directionality, and the two area-array cameras can image reflected laser spots and transmitted laser spots at the same time, so that the robustness is improved; the transverse deviation and the longitudinal deviation between the coordinates of the cross section of the inlet of the fixed-axis channel after mirror image transformation of the spatial centroid coordinates of the reflected laser spot image and the spatial centroid coordinates of the transmitted laser spot image are calculated, so that the target correction precision is high; and video stream data of reflecting and transmitting laser spots are processed, and a target correction result is fed back in real time, so that the target correction efficiency is relatively high.
