LDRD Seminar Series: ‘3D Digitization at Warp Factor 2’
Senior Experimental Systems Engineer Mark Hereld (MCS) will discuss his Laboratory-Directed Research and Development (LDRD) sponsored work at the LDRD Seminar Series presentation Tuesday, Aug. 8, 2017.
“3D Digitization at Warp Factor 2” begins at 12:30 p.m. in the Bldg. 203 Auditorium. All are welcome to attend.
Large-scale collections of objects held in natural history museums around the world comprise an estimated 1.5 billion specimens. They provide data for studies of taxonomy, biodiversity, invasive species, biological conservation, land management, pollination and biotic responses to climate change. These collections represent a significant societal investment in research and applied environmental science. However, they also present extraordinary challenges to researchers, archivists and curators. Working with the Field Museum of Natural History, we are developing a means of rapidly digitizing such large collections. The pinned insect collection, one of our first targets, includes over 4 million specimens. Once translated into the digital realm, they will be impervious to time, available for richly informative and powerful query-based exploration and analysis methods, accessible to a much wider community of researchers, and deployed in a wide range of outreach activities. In aid of this goal, we are developing a multi-camera head designed for single-shot digital capture of casually aligned pinned insects. In support of this experimental platform, we are developing methods for label capture for input to optical character recognition (OCR) and three-dimensional model capture in the face of uncertain orientation, position and occlusion. This presentation will discuss the challenges of high-throughput digitization of such collections, the methods and hardware we are developing to demonstrate feasibility and our progress to date. These methods are applicable beyond the collections found in museums. Transporting objects between the digital and physical realms is an increasingly useful activity with many benefits in industry as well as in scientific research and discovery. Areas of possible application include rapid assessment in advanced automated manufacturing processes, inventory management and capture and assessment of 3D scenes for forensic or field science applications.
Mark Hereld is a Senior Fellow of the Computation Institute, a joint institute of Argonne and the University of Chicago. He earned his Ph.D. in physics at the California Institute of Technology. For his doctoral research, he helped develop the 40-meter prototype for the Laser Interferometer Gravitational Wave Observatory (LIGO) and conducted the first systematic search for periodic gravitational radiation (from a millisecond pulsar) using this kind of detector system.
At Argonne, Hereld has developed large format parallel display and parallel rendering technologies to create the Active Mural, one of the first room-sized display systems capable of providing immersive visualizations of data from simulations run on supercomputers. He was part of the team that created the Access Grid, a paradigm shifting and award winning technology for collaboration between distributed sites. With collaborators at the University of Chicago, he has developed methods for simulating extremely large networks of biologically realistic neurons with the aim of understanding the origins of epileptic activity in the neocortex. Hereld is currently co-principal investigator for Small Worlds, a U.S. Department of Energy project to develop new technology for dynamic sub-diffraction limited 3D imaging of molecular processes in biological systems. He specializes in crosscutting research, connecting computational methods to physical systems.
Hereld came to Argonne from the University of Chicago where he was a senior scientist in the Astronomy and Astrophysics Department. There his research centered on the development of near infrared instrumentation for studying the evolution of stellar populations in galaxies near and far. He led the group that built the first significant optical telescope (24-inch diameter) to be deployed at the South Pole, and developed the attached cryogenically cooled near-infrared camera, which his research group used to measure the emission characteristics of the dark South Pole sky and to capture unique measurements of the unprecedented collision of comet Shoemaker-Levy fragments with Jupiter. The installation of this instrument (SPIREX) at the South Pole helped to establish the permanent observational astrophysics capability at the South Pole.
