Last week a person was killed while using the Tesla autopilot system. Elon Musk has taken the position that lidar is not required for autonomous driving, but this article in Forbes questions that belief.
From the article:
“The more fundamental problem is the sensor suite that Tesla has installed on its current production models. Autopilot relies on a single monovision camera system from Mobileye, a forward-facing radar sensor, two side-facing radars in the back corners and 12 ultrasonic sensors. Unlike seemingly just about every other autonomous system from a major automaker or supplier, lidar, a technology that uses lasers to measure distance, is conspicuously absent.
At the launch of Autopilot in October 2015, Musk made it clear that he doesn’t think lidar is necessary or even desirable for autonomous vehicle applications. Given the description that Tesla issued of the crash with a white truck against a brightly lit sky, it’s not entirely surprising that a camera failed to adequately recognize it.”
