This thesis analyses the performance that can be obtained in navigation applications by using the camera and sensors embedded in a mobile phone (and GPS when available). The project includes the development of image processing algorithms to extract useful observations for navigation. Navigation is based on the determination of the trajectory, ie, time, position, velocity and altitude. For a good navigation experience a period of calibration and characterization of embedded mobile sensors such as camera, accelerometers and gyroscopes is usually required. Finally for system validation is necessary to conduct a series of tests using a very specific navigation tool of the Institute of Geomatics. Project applications can be determined from the internal navigation in environments where GPS signals are not available or not good as shopping malls, airports, museums, large offices, hospitals ...
