Wearable autonomous navigation system for pedestrian and navigation method thereof

Abstract

The invention discloses a wearable autonomous navigation system for a pedestrian and a navigation method thereof. The wearable autonomous navigation system comprises five sensor modules and one comprehensive processing module, wherein the five sensor modules are arranged on the head, arms and feet of the pedestrian respectively; each sensor module comprises a first microcontroller, and an inertial measurement unit, a magnetic sensor, a gas pressure sensor and a first Bluetooth unit which are connected with the first microcontroller respectively; the inertial measurement unit comprises a triaxial accelerometer and a triaxial gyroscope; comprehensive processing module comprises a second microcontroller, and a wireless communication unit, a visual sensor, a satellite receiver, a second Bluetooth unit and a display unit which are connected with the second microcontroller respectively. The five sensor modules acquire a variety of navigation information and transmit the navigation information to the comprehensive processing module, and the variety of navigation information are fused to solve out a navigation result. Based on distributed wearable multi-point information acquisition, data fusion and data filtering are performed according to an inertial navigation method and other navigation methods, so that the pedestrian navigation performance is improved.

Description

technical field [0001] The invention belongs to the technical field of pedestrian navigation, and in particular relates to a wearable pedestrian autonomous navigation system and a navigation method thereof. Background technique [0002] Pedestrian navigation and positioning is an important emerging branch in the field of navigation.
