Wearable personnel gait-detection indoor-positioning system and method therefor

Abstract

The invention discloses a wearable personnel gait-detection indoor-positioning system and a method therefor. The wearable personnel gait-detection indoor-positioning system comprises attitude sensors, a data acquisition device, a data transmission unit and a data processing unit. The attitude sensors are installed respectively at leg parts and the waist part of a user. A first input end of the data acquisition device is connected to the attitude sensors. A second input end of the data acquisition device is connected to a correction module. The data transmission unit and the data processing unit are orderly connected to an output end of the data acquisition device. The data acquisition device acquires data measured by the attitude sensors. The data transmission unit transmits the acquired data to the data processing unit. The data processing unit carries out data synthesis processing to obtain attitude angles of the corresponding parts, carries out gait detection according to the attitude angles, acquires walk step length and a walk direction according to leg and waist length parameters of the user, and carries out vector superposition of the walk step length and the walk direction to obtain user positions in the room. The wearable personnel gait-detection indoor-positioning system and the method can simultaneously realize gait detection and positioning and has high positioning precision.

Description

technical field [0001] The invention belongs to the technical field of gait detection and indoor positioning, and more specifically relates to a wearable indoor positioning system and method for personnel gait detection. Background technique [0002] With the development of my country's economy and society, there are more and more demands for real-time gait and posture detection and indoor positioning of personnel. In some occasions, it is necessary to know both the body posture and the location of the personnel. For example, in hospitals, doctors often need to know in time that some patients with leg diseases or lower limb movement disorders are in certain places indoors and whether there is a fall accident, etc., to prevent danger from happening; and in some welfare institutions, some Blind or visually impaired people often need to know where they are indoors. Welfare home managers need to know the indoor location and whether there are dangers such as falls. Spatial locat...
