Start/Stop script messing with lane detection

[Deams51]

The lane detection cannot find a a trajectory if we use the stop/start script in chain.
I had to reboot the car to make it work again.

Example:
Booting the car & SSH
$ ~/Desktop/stop.sh && ~/Desktop/start.sh && ./driver/driver --cid=11 --freq=50
Everything is running fine. Then I stop using ctrl+c.
Starting again for new test:
$ ~/Desktop/stop.sh && ~/Desktop/start.sh && ./driver/driver --cid=11 --freq=50
Now the lane detection can't find a trajectory.

It seems to be a problem associated with the camera.
