To solve existing problems such as multi-station setting complexly and single station accuracy requires highly in pose measurement of flying targets,a new optical method for pose measurement is proposed.The method makes full use of the continuous image information and the corresponding target flight trajectory position data.First,starting point of target axis vector is determined by the target location data,and also the end point is acquired by the constraint equations of target axis vector.Then,the pose angles(including the yaw angle and pitch angle)can be calculated according to the relationship between the pose angles and the axial vector.Finally,the unique pose value can be obtained by the prior information.The corresponding simulation and accuracy analysis is performed,and the results show that the method proposed in this paper considering both the convenience and accuracy of measurement,has high application value.
