The MEMS/CCD head measurement method based on the principle of inertial positioning and optical positioning is presented to adapt to fast attitude position of the helmet in the modern war. The head attitude can be measured in real time by installing a set of MEMS inertial navigation system on the helmet through combination of CCD. Firstly, the measurement scheme is presented. Secondly, the mathematic model is established, and then the initial binding method is set and is validated through simulation. Simulation results show that the method can gain favorable rapidity and accuracy. The head attitude error angle can be estimated in less than 5 seconds and the attitude precision reaches to 2′. So the helmet attitude measurement and head real time tracking can be completed.
