System and method for tracking objects

摘要

A system, device and methods are provided for tracking objects, such as shipping containers and other movable items. In one embodiment, a method includes detecting an object based on detection of an object identification tag and detecting a marker during transport of the object, wherein detection of the marker includes determining location data of the marker. The method may further include storing position data for the object based on the location data of the marker, and outputting the position data for the object.

1. A method for tracking an object, the method comprising:
with a carrier device configured to transport the object, sensing identification information for the object stored in an object identification tag associated with the object; while transporting the object with the carrier device, sensing, with the carrier device, a marker which identifies a location of the marker; with the carrier device, determining a time of sensing the marker; with the carrier device, storing, in a data record for the object, position data for the object based on the location identified by the marker and storing the time of sensing the marker in the data record for the object; and outputting, by the carrier device, the position data for the object.
