Abstract

Approaches are disclosed for determining a position of a vehicle. An image of a tag is captured with a camera onboard a vehicle. A location of the tag is determined from data encoded in the image. A size of the image of the tag is compared to a baseline size of the tag. A capture position of the image of the tag is determined. A position of the vehicle is determined based on the determined location of the tag and the capture position.
