Learning Driving Models with a Surround-View Camera System and a Route Planner
share
For people, having a rear-view mirror and side-view mirrors is vital for safe driving. They deliver a better view of what happens around the car. Human drivers also heavily exploit their mental map for navigation. Nonetheless, several methods have been published that learn driving models with only a front-facing camera and without a route planner. This lack of information renders the self-driving task quite intractable. Hence, we investigate the problem with a more realistic setting, which consists of a surround-view camera system with eight cameras, a route planner, and a CAN bus reader. In particular, we develop a sensor setup that provides data for a 360-degree view of the area surrounding the vehicle, the driving route to the destination, and the low-level driving maneuvers (e.g. steering angle and speed) by human drivers. With such sensor setup we collect a new driving dataset, covering diverse driving scenarios and varying weather/illumination conditions. Finally, we learn a novel driving model by integrating information from the surround-view cameras and the route planner. Two route planners are exploited: one based on OpenStreetMap and the other on TomTom Maps. The route planners are exploited in two ways: 1) by representing the planned routes as a stack of GPS coordinates, and 2) by rendering the planned routes on a map and recording the progression into a video. Our experiments show that: 1) 360-degree surround-view cameras help avoid failures made with a single front-view camera for the driving task; and 2) a route planner helps the driving task significantly. We acknowledge that our method is not the best-ever driving model, but that is not our focus. Rather, it provides a strong basis for further academic research, especially on driving relevant tasks by integrating information from street-view images and the planned driving routes. Code and data will be made available.
