Problems solved by technology

[0004] The existing indoor positioning using triangulation positioning is relatively mature. The principle of triangulation positioning method is to use two or more detectors to detect the target position at different positions, and then use the principle of triangular geometry to determine the position and distance of the target. Therefore, The traditional indoor positioning algorithm needs to locate a point, which requires at least 3 devices or more, and the cost of equipment laying is relatively high

Abstract

The invention discloses an indoor navigation method and system and a storage medium. The indoor navigation method includes the steps that according to indoor topographic information, an indoor map isdrawn; according to the indoor map, path planning information of all areas is obtained; according to a current position of a terminal, a first device and a second device are obtained; according to thefirst device and the second device, a longitudinal two-dimensional coordinate graph is generated; according to the longitudinal two-dimensional coordinate graph, the current position information of the terminal is computed; according to the current position information of the terminal and the path planning information of all the areas, walking paths of pedestrians are generated. According to theindoor navigation method and system and the storage medium, only through the first device and the second device, the current position information of the terminal can be obtained after computing, the walking paths of the pedestrians are generated based on the current position information, and therefore the pedestrians can be navigated to specified end points under reasonable guidance; compared withan existing method for indoor positioning through three or above devices, through the indoor navigation method, the device laying quantity is decreased, the cost is reduced, and the method can be widely applied to the technical field of navigation.

Description

technical field [0001] The invention relates to the technical field of navigation, in particular to an indoor navigation method, system and storage medium. Background technique [0002] At present, in major shopping malls in China, whether it is the operator, the mall itself or the stores in the mall, almost all of them have arranged a large number of Wi-Fi hotspots. Theoretically, the navigation software can determine the user's location through the Wi-Fi hotspot that the user is connected to, and then cooperate with three or more nearby Wi-Fi hotspots. Technically, these Wi-Fi can reduce the positioning range to about 5 meters, comparable to outdoor GPS satellites. [0003] The current indoor navigation is divided into indoor positioning based on different hardware devices such as WiFi, ultra-wideband (UWB), Bluetooth, RFID, infrared, and ultrasonic waves. The distance is achieved by triangulation positioning algorithm. [0004] The existing indoor positioning using tri...
