BMW's Night Vision Pedestrian Recognition System
For those of you who haven't heard of this:
New BMW Technology
Their night vision camera uses software algorithms to calculate whether a particular shape is a person, and if so, where their location is relative to the car and if your speed and yaw rate are factors putting them in danger. If so, it gives you a subtle alert (big yellow warning triangle.)
Considering the technologies available to most CarPC users now (IR cameras, motion sensors, vehicle data on the fly), how difficult would it be to implement something like this? I'm presuming it's more of a software than a hardware problem, but either way, I wouldn't know where to begin. Could it be used to recognise traffic signs too?
