Cars can now navigate city streets using only cameras

While most self-driving cars rely on pricey laser sensors called LiDAR to 'see' the world, a new wave of vehicles is navigating Europe using nothing but eight small cameras. These cameras feed a massive neural network—a digital brain—that processes 1.3 gigapixels of data every second. This system doesn't just see objects; it uses a technique called photogrammetry to reconstruct a three-dimensional map of its surroundings with ten-centimeter precision.
