Pedestrian seamless navigation positioning method and system based on intelligent equipment and MIMU

Abstract

The invention relates to a pedestrian seamless navigation positioning method and system based on intelligent equipment and an MIMU. The method comprises the following steps of: receiving inertial navigation data of an MIMU inertial navigation module fixed on the body of a pedestrian holding the intelligent equipment in real time by the intelligent equipment through a short-distance wireless communication channel, receiving and detecting satellite navigation signals in real time, acquiring pedestrian navigation and positioning data by using an integrated navigation algorithm when satellite signal quality conditions are met, otherwise, acquiring pedestrian navigation and positioning data by using an inertial navigation algorithm. The intelligent equipment generates pedestrian navigation positioning data in real time and sends the pedestrian navigation positioning data to a cloud server, and receives and displays user group pedestrian navigation visual data sent by the cloud server. According to the method, only one piece of intelligent equipment and one MIMU inertial navigation module are used, seamless switching between integrated navigation and inertial navigation is achieved according to satellite navigation signal quality, navigation data of local and intra-group users are displayed in real time with the help of the cloud technology, and the method has the advantages of reliability, miniaturization, simplicity, easy use and the like.

Description

technical field [0001] The present application relates to the technical field of pedestrian navigation, in particular to a method and system for pedestrian seamless navigation and positioning based on smart devices and MIMU. Background technique [0002] Satellite navigation system has become a widely used pedestrian navigation technology because of its full-time, all-weather, high-precision, and continuous real-time characteristics. However, in indoor, underground, jungle, roadway and other environments, satellite signals are difficult to fully cover and are easily interfered, making it difficult for satellite navigation systems to play their due role. In response to the navigation and positioning needs of pedestrians in an environment with limited satellite signals, there are many indoor navigation and positioning solutions on the market, but most of them need to lay special navigation and positioning facilities in advance or use existing equipment in the environment as na...

Problems solved by technology

However, there are still some problems in the application process: first, the universality is not good enough, and the inertial navigation of the feet is not combined with the satellite navigation on the mobile phone to form a complete indoor and outdoor seamless navigation and positioning system; the second is the data There are blind areas in the collection, and pedestrian movement data cannot be collected in areas with limited satellite signals, let alone analysis and utilization of these data; third, there is no combination of traditional navigation technology and cloud technology to realize real-time monitoring and monitoring of pedestrian groups. Communication and big data analysis; Fourth, the practicability is not strong enough, there is no easy-to-use, mature and reliable software and hardware design, miniaturization and marketization are not enough
