摘要: In the field of indoor navigation, inertial measurement units (IMUs) are commonly used to track pedestrians. Unfortunately, in conjunction with dead reckoning localization approaches, position accuracy is degraded by accumulation sensor errors. Most pedestrian systems therefore adapted human gait patterns constraint this error growth. These interventions however make them ignore any user displacements different from doing steps, such as elevators and escalators, a result they fail full trajectory indoors. order avoid estimation failures, an elevator escalator detection algorithm proposed that capable detect incidences enhance elevator/escalator ride.
