AUTOMATED ANALYSIS OF DENTAL RADIOGRAPHIC IMAGES

Not Available This project will provide strong technical foundations for the development of software products and services that will enable collaborative design among development teams using disparate CAD and analysis packages. Issues to be addressed include: construction and maintenance of a robust central geometry representation comprising surface patches and trimmed surfaces; export of geometric data in user-defined formats to a variety of analysis codes; export of geometric data to a variety of CAD systems in editable form; reconstitution of edited data returned from client CAD systems to a form compatible with the central representation. We propose to utilize AeroHydro's patented Relational Geometry (RG) framework as the central representation. By capturing a broad variety of interobject relationships, RG provides fundamental benefits in editability and accuracy over conventional surface representations. The project will demonstrate capabilities to export editable CAD models from RG to a variety of CAD systems, using primarily DXF, IGES and STEP formats; to receive back edited data in these same formats; to compare returned and original data; to identify the elements that changed; to update the central RG model to reflect the changes. The project will build upon existing RG capabilities of AeroHydro's RGKernel, MultiSurf and Surface Works products. BENEFITS: Military: This technology will serve as the essential GEM component of TACOM's Automotive Product Development Framework
