Ok, I’m going to jump right into this. My husband and I rented a car to make our family vacation trip from Texas to Florida. We were given a newer Toyota Camry, as we requested a car of similar size to our car, which happens to be a 2001 Toyota Camry. My mind was just blown by this car. My husband veered off the road just slightly, and an alarm started going off in the car. I am in my 30s with 2 teenagers, so I thought nothing could surprise me. I was wrong. As soon as the alarm went off, I jumped in my seat in excitement and asked if it was what I thought it was. We have now been playing with this system to see how it works. I had to pick my jaw up off of my lap because HOW DOES IT KNOW??!!?? When there is a slight bend in he road, we don’t use a blinker, but we turn the wheel ever so slightly, and it doesn’t go off. However, if we’re in a straight lane and we turn the wheel so the car moves into the next lane a little or into the shoulder, we get the alarm. It doesn’t come on when we use the blinker, and I understand how that would work, but I can’t figure this out, and I don’t understand any materials I’ve found on it, so someone please, ELI5!

The car has a camera and a computer. The camera takes a picture and the computer combs through it and rates each part the image looking for lines. If it’s pretty sure that something is a line, it gives it a high score. If it isn’t sure, it gives it a lower score. When the computer is done, it has a pretty good idea where the lane markings are, because compared to the rest of the road, other cars on the road, trees and sky, the lane markings will truly stand out as the only pure lines in the image. And once you know where those lines are, it’s easy to tell whether the car is crossing them.
