When it comes to self-driving cars, the general axiom for sensors is “the more the merrier.” The safest systems are the ones that use a multiplicity of sensors, such as cameras, radar, ultrasonic, and LIDAR. Having these redundant sensors is the whole point: if one fails, the remaining sensor suite can help navigate the car to safety.
Mobileye, a company that specializes in chips for vision-based autonomous vehicles, believes in redundancy, but it also believes in the power of its camera-based system. At the Consumer Electronics Show in Las Vegas this week, the Intel-owned company demonstrated how one of its autonomous test vehicles navigated the complex streets of Jerusalem using cameras only.
