Abstract

We provide an indoor navigation method using compass and indoor plan, instead of digital indoor map.

System accepts indoor plan photos as the first input, processes the photo and combines it with compass to make the indoor plan photo act as a background of the compass. System then calculates the current relative coordinate in the photo and the photo scale. At this point user can mark the destination on the photo and draw his anticipated route on the photo. System accepts the destination and route as further inputs, automatically identifies turning points in the route, calculates key points’ coordinates, and start to provide the navigation to the user.

Apparatus and Method of Indoor Map Generation with Architectural Plan for Navigation

Background

 Nowadays, satellite navigation is the most popular way which people rely on for navigation. User can use it to arrive destination which is a long distance against departure place. Currently people are all using outdoor navigation tool at most times, for the indoor navigation, there is some ways, like:

Navigation by comprising real environment photo capture with existing server data Light source navigation and positioning
Sound source navigation and positioning
Digital indoor map navigation
Navigation with signal sender/receiver devices, etc.

 But all of above methods requires existing data, which the user might not have every time in a new building.

Problem:

 For most people who are in a new place would easily lose the way, especially in a huge shopping mall with many floors, although there usually is floor plan in the building. But in the most time, floor plan can barely help the people who is not quite sensitive with the direction. This group of people have to ask for help from front desk or other people.

Core Idea:


We provide an indoor navigation method using compass and indoor plan, instead of digital indoor map.
