Developing a Motion-Stereo Parking Assistant at BMW

For many drivers, finding and then navigating a vehicle into a suitable parking spot is a challenge-mainly because the driver cannot see around the vehicle or determine the size and shape of the parking space.Several automotive manufacturers, including BMW, now equip vehicles with side-view cameras, which drivers can use to examine blind areas around the car. These cameras provide only a visual representation (a two-dimensional video image) of the area, and are not well-suited to evaluating the size of a potential parking spot or warning the driver of hazards in the car’s path. These more complex tasks require a spatial representation. Some companies are working on ultrasonic- and LIDAR-based driver-assistance systems, but such systems impose the cost of additional sensors, and typically have relatively low range and resolution, not to mention low classification abilities.
