ITL and BFRL Researchers Honored with Best Paper Award

David Gilsinn and Dianne O’Leary of ITL’s Mathematical and Computational Sciences Division, along with Geraldine Cheok of BFRL’s Materials and Construction Research Division, won the Best Paper Award for their contribution to the 19th Annual Symposium on Automation and Robotics in Construction (ISARC 2002). Their paper, entitled “Reconstructing Images of Bar Codes for Construction Site Object Recognition,” was selected as top paper of the 88 manuscripts from 20 countries that were accepted for presentation. Sponsored by the International Association for Automation and Robotics in Construction, the conference was held at NIST on Sept. 23-25, 2002.

In their paper, Gilsinn, O’Leary, and Cheok described techniques for the automated recognition of bar codes from LADAR (laser distance and ranging) optics. In the process of sending and recovering optical signals from a scene, LADAR devices obtain three-dimensional data (distance, angle, and intensity) which can be used to develop three-dimensional models. Although image reconstruction techniques are well known in association with traditional optical systems, this work represents one of the first to apply them in the context of 3D scanners. While current scanners generate beams that are much too coarse to get good reconstruction, with technology changes leading to finer resolution beams, effective reconstruction of objects may become feasible.
