Navigation application in the building via two-dimensional barcode recognition

Abstract

The aim of this thesis was to create a navigation application working on the principle of recognizing two-dimensional graphical codes. This application should support the creation and editing of two-dimensional maps of the building and assign specific information to the objects on the map. The thesis describes the basic algorithms usable for indoor navigation, followed by a brief description of available techniques and methods of navigation. The description of QR codes used in this work to locate the position of the building is included as well. In the design part the study, more detailed description requirements are added and the concept of the application implementation is described. The model building used in the study presents the building as an object with floors and rooms. It distinguishes two types of rooms, the plain rooms on one floor and the rooms connecting the floors. The implementation is divided into map editing section and navigation section. Two applications have been created based on the requirements. FriBasicMapEditor, as editing application, provides functions for creating and editing two-dimensional maps of the building and matching QR code to objects in maps. The navigation application, FriNavigate uses a map created by FriBasicMapEditor application and provides for user the navigation functions in the building described by loaded map. The navigation is based on the recognition of generated images of QR codes. The application can be used to navigate in any standard building or used as a basis for more complex, respectively more extensive projects related to navigation in buildings.
