Abstract: In vehicle side impact accidents, it is very important to improve the protection ability of remote occupants. The China-new car assessment program (C-NCAP) 2024 version introduces the virtual evaluation project of side far-end occupant protection, in which the head offset is the key inspection item, which is crucial to the accuracy of the virtual evaluation of vehicle side impact. Therefore, this paper proposes a dummy head displacement analysis method based on high-speed camera. The coordinate system is defined by a three-coordinate measuring instrument and the dummy head point model is obtained. The TEMA 6D software is used to track the movement of key marker points to obtain the dynamic data of the dummy head during the collision. These data are applied to the evaluation of far-end occupant protection in actual vehicle side impact, which provides important data support for vehicle safety performance analysis and has practical application significance.
