bad adjustment of the receiver. Besides the signal reception, this module must be
capable of sending the information to the server module, where it is properly
analysed. In the current implementation, an Android Smartphone was used to
instantiate the GPS module, running a simple application that captures the GPS
coordinates and periodically sends them to the server module. Finally, the server
module, implemented as a desktop application, is responsible for most of the
processing activity: it receives the video frames from the media module, and the
GPS information from the GPS module, and processes the information in order to
obtain a valid and accurate positioning of the system. The CV-GPS processing is
performed in this module.
This architecture was implemented and tested using a personal vehicle, as
illustrated in Fig. 4 . In this Figure, it is possible to see the camera and the GPS
steady placed over the vehicle

' s dashboard, and the laptop, running the server

application.
