Abstract
Due to drift of measuremen of inertial measurement unit( IMU)
it is difficult to get accurate trajectory of pedestrian indoor
a scheme fusing multiple sensors information is proposed
include inertial measurement unit( IMU) and vedio camera
combined Kalman filtering with zero-velocity detection algorithm for parameters optimization. The simulation results show that the algorithm can effectively reduce the error of pedestrian trajectory.
