Abstract

Guidance is very important for one in an unfamiliar or even totally new place, especially staying in town with many crossed streets or lanes, typically for a traveler during his/her tourism. Mobile phone with camera has been taken as a useful tool for navigation for travellers. Pictures or video taken by mobile phones are used to identify traveller's position with method of visual localization. Localization of traveller is the basic step for navigation, but an exact and easy guidance could be more important and practical. This paper takes a full consideration of navigation based on mobile visual localization and provide traveller with an exact and easy guidance method. Mobile user captures a few photos or a short video around him/her, for example with his/her cell phone, and then sends it or them to a remote server via wireless internet. Remote server extracts visual features and matches them to pictures database to determine the traveller's position. Given a destination, Navigation Situation is generated and calculate proper rout between traveller's position and destination, then return traveller with a series of pictures marked with an arrow indicating the correct crossing and left/right turn should be taken. Following these marked pictures, traveller can get the expected place and it's just like labyrinth guidance.
