Evolving 3D sensing technology will play an increasingly critical role in improving the safety of smart and autonomous cars. By providing real-time data about the physical environment, the vehicle, and the driver, 3D sensors make it possible to create a comprehensive map of all objects surrounding the car, both near and far, and in 360 degrees. Backed by analytics, vehicles will be able to identify objects, track their relative velocity, and accurately predict their future position. The more extensive and accurate a mapping the vehicle has to work with, the better—and safer—decisions it can make.
