LED lights are known to cause some strange effects when photographed and filmed. While the banding you might see when photographing LED lights can be irritating, when it comes to cameras on autonomous cars, it might be a matter of life and death.
In this short video, scientist Steve Mould explains how and why LED lights pulse. He then gives an excellent explanation of why this poses a threat to self-driving cars and what can be done to resolve it.
Along with an insight into how LEDs work, there are some intriguing reflections on problem-solving and the evolution of technology. If you're a BMW driver who lives in the U.S., please don't watch if you're easily offended.
If Mould looks vaguely familiar but you’re not sure why, he’s a physicist and stand-up comedian who shot to fame upon discovering what subsequently came to be named the “Mould Effect.” If you want to geek out over self-siphoning beads and their strange behavior, be sure to check out Mould’s very entertaining TED Talk.
Is a global shutter the solution? How else could this problem be solved? Are European indicators better than American turn signals? Leave your thoughts in the comments below.
