42. Pose of I-Beams for Construction Site Automation
Published: 9/21/2004
Authors: David E. Gilsinn, Geraldine S Cheok, Alan M. (Alan M.) Lytle
Abstract: Automation of construction processes can result in reduced project costs and increased worker safety. A process that lends itself to automation is the picking and placing of objects. However, determining the pose (position and orientation) of an ob ...

43. Triangular Meshing and Volume Determination
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7142
Published: 7/1/2004
Authors: Christoph Johann Witzgall, Geraldine S Cheok
Abstract: Parametric studies are reported for investigating the feasibility and accuracy of calculating volumes from LADAR scans of artifacts. The TIN (=Triangulated Irregular Network) technique was employed to construct surfaces on which the volume calculati ...

44. Performance Evaluation Facility for LADARs
Published: 4/12/2004
Authors: Geraldine S Cheok, William C Stone
Abstract: The use and scope of LADAR (laser detection and ranging) applications continues to expand as the technology matures. This growth is reflected in the National Institute of Standards and Technology s (NIST) experience with research into the applicatio ...

45. TIN Techniques for Data Analysis and Surface Construction
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7078
Published: 1/1/2004
Authors: Christoph Johann Witzgall, Javier Bernal, Geraldine S Cheok
Abstract: This report addresses the task of meshing point clouds by triangulated elevated surfaces referred to as TIN surfaces. It describes the general features of this approach, and refers to prototype TIN software employed at NIST for research into the ana ...

46. Deconvolving LADAR Images Of Bar Codes for Construction Site Object Recognition
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7044
Published: 10/1/2003
Authors: David E. Gilsinn, Geraldine S Cheok, Dianne M O'Leary
Abstract: This report discusses a general approach to reconstructing ground truth intensity images of bar codes that have been distorted by LADAR optics. The first part of this report describes the experimental data collection of several bar code images along ...

47. Proceedings of the LADAR Calibration Facility Workshop, June 12-13, 2003
Series: NIST Interagency/Internal Report (NISTIR)
Published: 10/1/2003
Author: Geraldine S Cheok
Abstract: The use and scope of LADAR applications continues to expand as the technology matures, but standard protocols or procedures for calibrating and testing of LADARs have yet to be developed. While selections of LADAR instruments are generally based on ...
