TIN Techniques for Data Analysis and Surface Construction
Christoph J. Witzgall, Javier Bernal, Geraldine Cheok
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 analysis of 3D point data acquired by LADAR instrumentation. Inherent in the TIN approach is the establishment of neighbor relations between data points, which provide the basis for various smoothing, filtering and screening procedures. In particular, the TIN structure is utilized to define the boundary of a planar point set. The report provides theoretical background for subsequent documentation of experimental results about the accuracy of LADAR data and their processing by TIN methods.
