Problems solved by technology

The positioning of the image analysis method requires the collection and reprocessing of indoor images. When the indoor light is dim, this method is limited and the data processing time is very long, and the real-time positioning performance is not good.
In practical applications, these solutions are difficult to achieve high-precision, high-real-time and universal applicability for the positioning of personnel in unknown environments

Abstract

The invention discloses a wearable three-dimensional indoor positioning device and method based on attitude angle measurement. The device comprises inertia sensors, a barometric sensor, an embedded processor, a communication module, a power supply module and a three-dimensional indoor building model display module. The inertia sensors are used for measuring attitude angles and acceleration signalsat left and right ankles, and the barometric sensor is used for collecting barometric signals of the location of a person. Data obtained by the inertia sensors and the barometric sensor are subjectedto information fusion in the embedded processor, the processed data are sent to an ad-hoc network terminal through a Bluetooth module of the communication module, the ad-hoc network is used for sending the data received by the terminal to an ad-hoc network base station, then data packets are transmitted to the display module through a serial port, and the display module displays information likepersonnel real-time positions. The power supply module supplies power to the embedded processor. The device and method improve three-dimensional indoor positioning precision and real-time performance.

Description

technical field [0001] The invention relates to the field of indoor positioning, in particular to a wearable three-dimensional indoor positioning device and method based on attitude angle measurement. Background technique [0002] A variety of indoor positioning technology solutions have been proposed in the prior art, such as wireless sensor positioning technology, ZigBee technology, infrared technology, radio frequency tag identification technology, ultra-wideband technology, Wi-Fi positioning technology, light tracking positioning technology, and image analysis, Beacon positioning, computer vision positioning technology, etc. However, these technologies are not universally applicable and real-time, and all require external equipment to assist positioning. Wi-Fi positioning technology needs to estimate the location of the receiver by setting up a Wi-Fi network indoors. The positioning of the image analysis method requires the acquisition and reprocessing of indoor images...
