Method for implementing area navigation through reading image code

Abstract

The invention relates to a method for realizing area navigation by reading image coding, comprising: a navigation tag is set, and the surface of the navigation tag is preset with the image coding; a navigation unit is provided with a navigation information generating system which can generates navigation route according to the destination and the current location of the user and generates navigation information; an image reading unit of the navigation unit is used for acquiring optical image, an image sensor converts the optical image into digital signals, the image coding is analyzed out by a digital processing unit, and the corresponding information code is obtained by decoding; a processing module controls the navigation information generating system to search whether the information code which is consistent with the information code obtained by decoding is available; if yes, the position marked with the information code is taken as the current location of the user and input into the navigation information generating system; the navigation information generating system generates the navigation information; an information output module is used for outputting the navigation information generated by the navigation information generating system.

Description

【Technical field】 [0001] The invention relates to a method for providing navigation information to users, in particular to a navigation method for realizing small area navigation by reading image codes. 【Background technique】 [0002] Traveling has always been a popular leisure activity. Especially in recent years, with the improvement of people's living standards, tourism consumption expenditure is also increasing, and the tourism industry is booming. In order to allow every tourist to enjoy the navigation information anytime and anywhere, the patent of Chinese Patent No. 93219301.3 is a utility model named "Wireless Electronic Voice Guide Device". This device is actually a small dedicated wireless transmitting station. When you bring the rented receiver close to the scenic area, you can receive guide information through wireless methods such as infrared. In addition, the patent of Chinese Patent No. 99113639. X is called "self-help tour guide system and method thereof". ...

AI Technical Summary

Problems solved by technology

Existing tour guide devices or tour guide systems need to use wireless networks to transmit tour guide information. However, wireless networks are not only extremely expensive, but also require continuous post-maintenance, and it is difficult to set up many base stations in areas with dense exhibitions such as museums and exhibition halls. Big

[0003] In addition, the current navigation technology mostly uses received wireless signals for positioning and navigation, and if the information is not received wirelessly, it is impossible to identify the area where the user is located, and thus cannot locate and navigate.
