摘要：Smart phones are widely used as navigation aid nowadays. Most of the smart phones provide a built-in Navigator or Map application with some sort of GPS capability. These navigation applications provide accurate navigation for outdoor location using GPS unit of the Smartphone. But providing accurate navigation inside a closed building is still a challenge. Several solutions are available in the market for indoor navigation using Bluetooth, Wi-Fi and AGPS. But their reliability of navigation in all given scenarios is still a challenge. In this paper we propose a elicit a cost effective and 3D latitude, longitude and altitude smart phone solution which helps in indoor navigation with the help of QRcodes. The QRcodes are used in this context to provide location information to the user optically. QRcodes will be used all across the building to carry the information required for the navigation systems. QRcodes will be used all across the building to carry the information required for the navigation system.
