The attitude parameters of the 3-D movement of an aircraft are indicators of an aircraft's operating state. A method of sequence screen-spot imaging based on the laser-aided cooperative target is presented to support the measurement of aircraft attitude parameters in ground test experiments. The laseraided cooperative target is mounted on the aircraft surface and the laser spots are projected onto two fixed screen. High-speed cameras synchronously record the position of the laser spots on the screen. According to the position transformation relation between the coordinate systems, the aircraft attitude parameters can be calculated by analyzing the position of the sequence screen-spot image, which will change along with the aircraft attitude. A global calibration method based on the coplanar control points is proposed for the calibration of the measuring system. The experimental results show that the measurement accuracy of the attitude parameters for the proposed method is no more than 3' under the rotation angle from -10° to +10°. The proposed method can amplify the motion attitude of the aircraft by mounting the laser-aided cooperative target on the surface of the aircraft, which breaks the limitation of the geometric condition of the aircraft and improves the measurement accuracy.
