Benefits of technology

This patented technology allows for easier installation without requiring expensive equipment or complicated procedures compared to previous systems that required manual installations at each location. It also provides an efficient way to navigate through complex environments such as buildings while maintaining accurate positional data.

Problems solved by technology

There has long existed a problem where individuals may remember things when visiting places beyond their familiarity level because there was no way to track them around from inside buildings during travel. Existing navigational tools were developed but did little help us navigate through complicated environments like shops and stores while still having issues related to maintaining personal memories and keeping sensitive areas safe away from harmful environmental elements. Additionally, existing solutions only work well within specific scenarios and lack flexibility towards changing conditions overtime.

Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0050] The present invention provides a map-free indoor navigation method and system based on densely deployed APs. The flow chart of the method of the present invention is shown in the attached figure 1shown, including the following steps:

[0051] Step 1. Collect and record the data information of the user during indoor activities through the trace collection module;

[0052] Step 2, when the user needs to navigate, the data preprocessing module processes the RSSI information collected by the reference trace collection module and uses the collected user steps and rotation angle information as reference data;

[0053] Step 3, preprocessing the current position data information collected by the navigation trace collection module as input data;

[0054] Step 4. Match the input data with the reference data through the matching module: if the user is on

Abstract

The invention relates to a map-free indoor navigation method and system based on densely arranged AP, which belongs to the field of navigation technology. According to the invention, data information about a user during indoor activities are acquired and recorded by a trace acquisition module; when navigation is needed, a data preprocessing module processes RSSI information acquired by a reference trace acquisition module and uses the processed information, acquired step numbers of the user and information of the rotation angle of the user as reference data; current location data information acquired by a navigation trace acquisition module is preprocessed and used as input data; and the input data is matched with the reference data in virtue of a matching module, and the system gives out corresponding navigation prompts according to different position states of the user. The map-free indoor navigation method and system provided by the invention make full use of the fact that wireless AP is extensively arranged and realize self navigation of the user without an indoor map or plane graph in virtue of a novel, simple and effective path matching algorithm.
