Aspects Concerning the Calibration Procedure for a Dual Camera Smartphone Based ADAS
We present the architecture of an Advanced Driver Assistance System (ADAS) based on common dual camera smartphones, emphasizing on the calibration procedure which is active during the initialization phase (prior to the actual driving). NAVIEYES project attempts to make use of the video information received from both the front and the rear cameras of the phone in order to infer and alert drivers upon potential dangerous situations. This study focuses on the information received from the front camera. 10 different mobile devices were tested, in order to choose the most powerful and ergonomic platform. A calibration experiment is carried by 22 subjects, and the first version of the application is tested using a driving simulator. The system is deployed on a real car, and several warning paradigms such as audio, video and mixed alerts are also analyzed. We present the HCI questionnaire, analyze the data and propose further developments.
