cars to ‘see’ 3D objects in their path.
are bulky, ugly, expensive, energy-inefficient — and highly accurate.
They can add around $10,000 to a car’s cost. Despite their drawbacks, most experts have considered LiDAR sensors the only plausible way for self-driving vehicles to safely perceive pedestrians, cars and other hazards on the road.
Scientists from Cornell University in the US have discovered that a simpler method, using two inexpensive cameras on either side of the windshield, can detect objects with nearly LiDAR’s accuracy and at a fraction of the cost.
lower-cost cars, or as a backup method in higher-end cars that are also equipped with LiDAR.
