An automotive vision system

On occasion I slide from industrial machine vision into the world of automotive vision systems – the kind of things that will give us self-driving cars in the near future – and today I thought you might like to take a look at one.

Japanese auto parts maker Denso has just announced a new vision sensor for active safety. The link takes you to their press release, and if you scroll down to the bottom you’ll find a photo of an in-car system – the kind of thing that goes in to high-end BMW’s and Mercedes.

Details of the system are sketchy. We’re told it has a color camera to better handle various colors of lane markings and to distinguish between taillights and headlights. We’re also told that’ it’s smaller and has a higher upper temperature limit.

And on the subject of color, here’s something I’ve wondered about for a while: how does it see lane markings in the dark? In snow? In fog?

I’m just asking.

How does human see markings? No way..

I think camera can actually see more, because visible range can be extended to UV- and/or NIR-area. That however doesn't help when everything is blocked by snow.
