ABSTRACT:
A system for generating orientation information includes a reflector, an image collection system, and a processor. The image collection system is configured to collect at least two sets of image data, where one set of image data includes a stronger indication of the reflector than the other set of image data. The two sets of image data are collected using at least one reflector with some orientation-specific characteristic or a reflector integrated into a device that includes some orientation-specific structural feature. Once collected, the two sets of image data are used to generate orientation information related to the reflector. In particular, orientation information related to the reflector is generated by taking the difference between the two sets of image data.
