72. Terrain Characterization from Ground-Based LADAR
Series: Journal of Research (NIST JRES)
Report Number: NIST
Published: 3/17/2003
Authors: Christoph Johann Witzgall, Geraldine S Cheok, David E. Gilsinn
Abstract: Test runs of Army Research Laboratory s (ARL) autonomous vehicle (Experimental Unmanned Vehicle, XUV) were followed by the acquisition of high resolution scans of selected regions of the test course. These scans were used to i) determine terrain ...

74. 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 ...

76. Using LADAR to characterize the 3-D shape of aggregates: Preliminary results
Published: 3/1/2006
Authors: Edward Joseph Garboczi, Geraldine S Cheok, William C Stone
Abstract: In previous publications, we have shown how using x-ray computed tomography to obtain the raw 3-D data for the coordinates of the surface, and then converting this raw data into an analytical function for the surface via an expansion in spherical har ...
