Abstract: A system includes a processor and a memory in communication with the processor, the memory storing instructions that when executed by the processor cause the processor to receive from a portable device coupled to a vehicle one or more images and at least one sensor datum, compute based, at least in part, upon the one or more images and at least one sensor datum a pose estimate of the vehicle, identify based, at least in part, upon the pose estimate a geofence containing the pose estimate; and if the geofence comprises, at least in part, a parking zone, transmit a parking validation to the portable device.
