Massachusetts Institute of Technology (MIT) researchers have invented a system to enable autonomous vehicles to navigate complex environments by checking a basic global positioning system-like map and employing video feeds.
The autonomous control system first "learns" humans' steering patterns on suburban streets via the map/video combination.
In training, a convolutional neural network correlates steering wheel spins to road curvatures, as seen through cameras and the inputted map.
Once trained, the system can pilot a car along a preplanned route in a new area by emulating a human driver.
The system also continuously identifies any mismatches between the map and road features to sense whether its position, sensors, or mapping are wrong, and makes appropriate course corrections.
Said MIT’s Alexander Amini, “With our system, you don’t need to train on every road beforehand. You can download a new map for the car to navigate through roads it has never seen before.”
