Abstract
A method and apparatus for detecting and estimating the dimension of a trailer are presented. The method includes: capturing information on surrounding static infrastructure; determining the existence of a trailer based upon the captured information on the surrounding static infrastructure. When it is determined that a trailer is present, the method further includes: filtering detections associated with the existence of the trailer; identifying one or more regions on a trailer based upon the filtered detections, the regions corresponding to repeated reflections having an amplitude equal to or greater than a predetermined amplitude threshold with a substantially constant range relative to a fixed origin; and determining at least one of a width, length, and height of the trailer based on the identified regions.
