The World’s Most Amazing Camera: Part 2
I recently had the opportunity to ride in one of the newer Tesla electric cars. The dashboard had a single touchscreen which displayed a perspective view of the vehicle itself – as if seen by a bird following the vehicle by 300 feet at about 100 feet in altitude. The screen also displayed grayscale model representations of all surrounding vehicles, along with the markings on the road, the speed limit, nearby traffic lights, and other driving information. In principle, you could drive the car without ever looking out the window by looking only at the screen. Apparently, cameras surrounding the vehicle feed images into a computer which constructs a 3D virtual model of its environment, which is then displayed on the screen. In other words, it does in a very limited way what your eyes and brain do with much higher fidelity every second of your conscious life.
