Abstract: Emergency escape simulation for civil aircraft crew helps to identify the potential problems of crew escape
hatch design during the early development of aircrafts, and ensures the safety of crew members. This paper presented
a mixed-reality simulation system for emergency escape of civil aircraft flight crew. To solve the key problem of
human body virtual-physical matching, an optical-inertial hybrid whole-body human motion capture method was
proposed. The method, working together with the Kinect2-based human body key dimension matching technique, can
effectively improve the efficiency and robustness of human body virtual-physical matching. The proposed
mixed-reality simulation system has been successfully applied to the development of large domestic aircrafts.
Experimental results show its efficiency in the evaluation of crew escape hatch design.
