Intelligent spectacle based worker navigation system and method

Abstract

The invention provides an intelligent spectacle based worker navigation system and method. The method comprises the following steps: S1, a sensor unit is adopted to acquire user position information, and the acquired user position information is subjected to positioning calibration by a positioning unit; S2, position information of other correlated users is acquired by a communication unit; S3, position information of different users is input in a navigation calculating unit, and navigation paths between the user positions are calculated according to indoor map information of a memory unit; and S4, each correlated user adopts an indicating unit to perform real-time path navigation. Through introduction of intelligent spectacles, the whole navigation system structure is simplified, the cost is reduced, and moreover, real-time navigation can be conveniently and rapidly performed on more than two workers in an active state.

Description

technical field [0001] The present invention relates to navigation technology, in particular to a personnel navigation system and method based on smart glasses. Background technique [0002] In the field of navigation, the current outdoor navigation technology mainly uses GPS to achieve precise positioning for navigation, and its accuracy is about 5-20 meters. When using mobile signal positioning, the accuracy is poor and it will face the problem of confidentiality. When using navigation, GPS is mainly used to locate fixed targets, and does not have the function of user interaction. The use of satellite signals in indoor navigation will face large signal attenuation, which will lead to inaccurate positioning. However, the commonly used wireless positioning technology has not realized the relevant real-time positioning shared navigation technology, usually using radio frequency communication or through signal hotspots. The strength fitting of the network is used for position...

Problems solved by technology

[0005] In the current large-scale venues, when people need to be searched (such as children lost, visitors lost, looking for personnel from other laboratories to cooperate, etc.), the broadcast system can be used at the service desk to search for people. When the sound is loud or noisy, the sound of the broadcasting system may not be clearly conveyed, and the broadcasting system may increase the noise pollution of the indoor environment

[0006] The scheme mentioned in Chinese patent CN201110421695.7 has the following disadvantages: ①It is necessary to lay a radio frequency communication network in the entire indoor space to realize the positioning problem of the person to be searched, and the cost is relatively high; 2.The person to be searched must wear a radio frequency identification tag, the tag It must be identifiable by the indoor radio frequency network and distinguished from other tags; ③ There must be a well-developed monitoring device in the shopping mall so that facial images can be collected in time for personnel identification, which is costly and may not work effectively in a complex environment with personnel; ④ Without auxiliary communication, The searched person may not know that the searcher is searching, and the search work may become complicated due to the constant movement of the location, and the system efficiency is low; produce trouble
