Aiming at the accuracy of the motion posture of missile servo system during practical launching, a high speed camera dynamic measurement system is designed. The system uses multiple high speed cameras as image acquisition sensors and image processing technology to realize the motion posture dynamic acquisition of the missile composite servo system. Then an automatic acquisition and processing of dynamic data for motion characteristics is completed by software programming. Finally a dynamic motion characteristics calibration for missile servo system can be realized. Research results show that the technology has the advantages of strong environmental adaptability, high measuring efficiency, and accurate and stable system accuracy.
