The measurement principle and working process are studied. The motion fuzzy value of measurement system, synchronization error of flash system, Camera distortion error and image feature point extraction error are analyzed. The coordinate measurement error of the measurement system characteristic point is synthesized. On this basis, the attitude measurement error of the measurement system is calculated according to the definition of attitude angle and the error transfer mechanism, and the calculation results show that the error of attitude measurement of projectile is less than 0.8'. The process of error analysis shows that the camera distortion error and feature extraction error are the main errors among many error factors affecting the measurement accuracy.
