Scientists have developed two new smartphone-based systems for driverless cars that can identify a user's location and various components of a road scene such as street signs, pedestrians and buildings in places where GPS does not function.<br/><br/>Researchers said that the systems can perform the same job as sensors costing tens of thousands of pounds. The systems have been designed by researchers from the University of Cambridge in UK.<br/>Although the systems cannot presently control a driverless car, the ability to make a machine 'see' and accurately identify where it is and what it is looking at, is an important aspect of developing autonomous vehicles and robotics.
