Problems solved by technology

[0004] Most of the existing indoor positioning technologies require prior information, such as the deployment of beacon nodes in advance, the establishment of fingerprint databases in advance, etc. Although inertial navigation can be positioned without prior information, the accuracy of inertial navigation alone is not high, so Existing indoor positioning technology cannot adapt to complex indoor environments

Embodiment Construction

[0034] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0035] Any feature disclosed in this specification, unless specifically stated, can be replaced by other alternative features that are equivalent or have similar purposes. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0036] A specific embodiment of the present invention comprises the following steps:

[0037] 1. Wear the positioning terminals I and II on the staff's body. In order to obtain better results, in a preferred example, wear the positioning terminal I on the staff's feet to fully perceive the changes in the staff's walking. Put the positioning terminal II Wear it on the head of the person to obtain a 360-degree two-dimensional plane scan.

[0038] The positioning terminal I is an inertial measurement m...

Abstract

The invention discloses an indoor location method, relates to a location technology, and aims to provide an indoor location method without needing prior information. The method is technically characterized in that a first location terminal and a second location terminal are wore by a worker; when the worker is located at an initial position, the second location terminal acquires a 360-degree two-dimensional plane scanning chart of an indoor space; the first location terminal detects whether the worker finishes one step, and the second location terminal is informed if the worker finishes one step; after the second location terminal receives the inform, the second location terminal acquires a 360-degree two-dimensional plane scanning chart of the indoor space of the current position; the two 360-degree two-dimensional plane scanning charts are scanned and matched, so that a two-dimensional plane coordinate, relative to the initial position, of the current position of the worker is acquired.

Description

technical field [0001] The invention relates to positioning technology, in particular to an indoor positioning method. Background technique [0002] With the continuous development of modern society, the urbanization process is accelerating, and the buildings are also developing towards large-scale and high-rise buildings. People spend 80%-90% of their time in indoor environments (including underground, mines, tunnels, etc.). These changes have increased the requirements for indoor location services, and the demand for high-precision indoor positioning is rapidly increasing. [0003] At present, there are many kinds of indoor positioning technologies, which can be divided into two categories: ① Local indoor positioning, such as wireless local area network (WLAN), radio frequency tag (RFID), Zigbee (Zigbee), Bluetooth, ultra-wideband (UWB), geomagnetic field Strong, infrared positioning, light tracking positioning, computer vision positioning, ultrasonic positioning, inertia...
