Research on RFID in Construction ...

... "The proposed work would involve investigation of 1) the ability of using a LADAR to acquire information (such as color, type of material, distinct patterns, fiducial point identifiers, etc,) about an object in addition to range data, and 2) the fusion of LADAR and other sensors. These other sensors could be a) RFID tags that contain encrypted data about the scanned object, i.e, beam, column, part number, etc., b) micro-reflective sensors arranged in a standardized pattern or at pre-determined fiducial locations on an object to allow for identification, and/or c) a camera to provide a concurrent image of a scanned scene. The additional information from the hybrid LADAR does not identify objects per se, but is used to aid in object identification. Additional intelligence will have to supplied/added to a) pick out and extract the data (points) from a point cloud for further processing, and b) correctly identify the object. In the first instance, user intervention is the most likely source of this intelligence. In the latter instance, the intelligence could be in the form of user intervention, image processing algorithms (if a camera is used), and/or a database containing objects that would most likely be found in a particular scene.
