Study on high accurate and robust head pose tracker for cockpit environment

The head pose tracker consisting of two complementary inside-out tracker and outside-in tracker is designed according to complex cockpit environment and then a novel hybrid tracking approach composing of two extended Kalman filters and one fusion filter is proposed to fuse the poses from the inside-out tracker and outside-in tracker. An experimental setup was established to simulate head pose tracker and verify the proposed hybrid tracking approach. The primary experimental results show that our head pose tracker is capable of achieving more accurate and stable data of position and orientation as well as better robustness compared with using single inside-out or outside-in tracker. It also validates the rationality of the tracker configuration and the usefulness of our hybrid tracking approach.
