Raspberry Pi + Picam?

I must admit "Raspberry Pi!" is my kneejerk response to just about any custom digital look-see project.
But why not? Cheap as chips and what ever you want to do, someone probably already did 80+% of it for you because there is such a high nerd-base using them.
That is indeed correct. I have been busy lately with other stuff, but will look more into detail to what would be needed to make this work.

The imu will not only give you everything you need so I can't understand why you are thinking of turning the car into a giant wireless mouse...
You could even buy a 20Hz GPS and connect it to RTK systems (to have a 1cm precision), that would give you a, let's say, precise course.
From the 9dof IMU you do some sensor fusion, smart kalman filtering, and get absolute orientation and acceleration vector. But this is very noisy, having a value that is 1deg plus/minus 2deg is not that good :p.
It will be good to tell you some noisy movements, but not good for a precise overall result. I'm talking about the less than 10usd chips you can readily buy, not complex laser cool stuff.
These are all indirect measurements, and even "double" indirects. A camera on the ground is as truth as it gets.
The idea of this "exercise" is to make something that today costs thousands, for pennies throwing some nerdism into it, to put it some way.
