Trivial hacking is probably unlikely. Vehicles generally use CAN bus, but whether or not the camera data is available on the bus... I have my doubts, but if it's there, that'd be pretty cool. My guess would be there's a dedicated image channel off the main bus--but that's just a guess. I'd be interested in knowing if it's on the general network. It is peer-to-peer so in theory it can be deterministic, so maybe it is.
- blcArmadillo 8y agoYes, it's definitely not running over CAN as CAN doesn't provide enough bandwidth for cameras. Usually the cameras are connected using LVDS or in newer cars, ethernet.
- matt_the_bass 8y agoLvds? I assume the camera is some feet from the processor. Can lvds really be usedthat far?
- davelnewton 8y agoI don't know why not; IIRC FireWire was LVDS (4+m), and LVDS doesn't specify ("care about") distance, just loss between driver and receiver. I vaguely recall lossless transmissions between 10-30m, which is more than enough for a vehicle.
