Localização em ambientes internos utilizando PDR e Wi-Fi

Abstract

Internal positioning systems allow the localization of people or certain objects indoors, as well as assist in navigation and orientation. Proposals for indoor location systems based on only one technology have achieved unsatisfactory performance in localization, mainly due to the limitations in relation to the conflicting characteristics present in these environments. This work aims at the development of a hybrid location system, integrating the PDR and Wi-Fi technologies, which aims to provide the location of a user in an internal environment, allowing the user to move around and visualize their current location through a representation on a map. The results were satisfactory, including the direct influence of factors such as: physical characteristics (height, body mass, size of the past), smartphone location, speed of the adopted march and adoption of constant movements.
