Indoor Positioning Using the Modified Fingerprint Technique
(IJIRCCE, 2013-12)
The Wi-Fi positioning systems available for enclosed spaces use the existing network infrastructure to calculate the position of the mobile device (MD). The most commonly used parameter is RSSI (Received Signal Strength ...
WiFiPos: An In/Out-Door Positioning Tool
(IJCTT Foundation, 2013-12)
Geographical location solutions have a wide diversity of applications, ranging from emergency services to access to tourist and entertainment services. GPS (Global Positioning System) is the most widely used system for ...
Fingerprint Database Variations for WiFi Positioning
(IJCT Foundation, 2013-12)
Indoor positioning systems calculate the position of a mobile device (MD) in an enclosed environment with relative precision. Most systems use WiFi infrastructure and several positioning techniques, where the most commonly ...
Indoor low-cost localization system for controlling aerial robots
(Pergamon-Elsevier Science Ltd, 2017-04)
This paper presents a low-cost localization system to guide an Unmanned Aerial Vehicle (UAV) in indoor flights, considering an environment with invariant texture and typical indoor illumination. The first contribution of ...
Hybrid vision-based navigation for mobile robots in mixed indoor/outdoor environments
(Elsevier Science, 2015-02)
In this paper we present a vision-based navigation system for mobile robots equipped with a single, off-the-shelf camera in mixed indoor/outdoor environments. A hybrid approach is proposed, based on the teach-and-replay ...
Indoor Air quality related to occupancy at an air-conditioned public building
(Brazilian Archives of Biology and Technology, 2010-02-01)
Com o objetivo de caracterizar a influência da ocupação na qualidade do ar interior, um edifício público com sistema de ar condicionado foi selecionado. As variáveis ambientais consideradas incluíram contagem total de ...
Magnetic-field feature extraction for indoor location estimation
(Springer, 2013-09-16)
User indoor positioning has been under constant improvement especially with the availability of new sensors integrated into the
