  25. Next Engine 3D Scanner This 3d scanner uses laser light to capture both surface geometry and RGB color. Like Cyberware, the object is rotated through a “stripe” of laser light and delivers both geometry and RGB color. http://www.youtube.com/watch?v=bssjToihGVU

  27. Touch probe scanning to milling • CENTROID's Digitizing will automatically copy any 2D or 3D contour and will automatically create the G code program to machine the reproduction. Great for reproducing machinery Cams, Molds, Plugs, Cylinder head combustion chambers, EDM electrodes, and any free form shape. http://www.youtube.com/watch?v=IcVv1So1n_8&feature=related

  28. Touch probe scanning to milling Roland MDX – 40 The machine in our lab converts from a “touch probe” digitizer to a very fine CNC mill. You can “capture” 3D data then turn around and mill out the resulting geometry. http://www.youtube.com/watch?v=aPmp-IkyNcE

  29. 3D Data Capture (optical) This unique approach projects a random light pattern on a person and captures a 3-D image in two thousandths of a second with synchronized digital cameras arranged around the subject at precise angles. By calculating the displacement of the light patterns, the subject's exact surface geometry and accurate surface texture map are built in seconds and then fused mathematically.

  30. Image-based Scanning with Digital Cameras 3D Face Authentication • Development of algorithms for representation, extraction, segmentation, query and matching of 3D facial shapes for authentication. • Novel approach took advantage of the 3rd dimension to greatly increase accuracy and reliability of the data. • Researchers examined face geometry and curvature to analyze facial features that are invariant to expressions and other changes such as facial hair. • The project involved capturing, creating, and archiving of over 1500 faces in 3D. • Supported by a 3 year grant from the National Science Foundation.

  37. Optical digitalization of Charles Bridge Sculptures 1999 the State institute for the Care of Historical Monuments in Prague with the support of the Czech Ministry of Culture began a long-term project, monitoring the Charles Bridge sculptures. The Charles Bridge, dating from the 14th century, is not only a significant historical monument, but also a gallery of baroque sculpture. The sculptures and sculpture groups are affected by degradation and the original objects are being gradually replaced by copies. Non-destructive measuring methods, including a detailed photo documentation was used. To actually get the 3D form, the "flat pictures" can not give enough information. Therefore an accurate digitizing was needed, producing data which can easily be archived, compared and used for making a replica if needed. SLA of red blood cell

  38. Optical digitalization of Charles Bridge Sculptures The 6 meter high sandstone sculpture of Saint Vojtech by the 18th c. sculptor Ferdinand Maxmilian Brokoff was the first element to be digitized. The Czech company, MCAE, utilized the optical measuring systems TRITOP and ATOS from GOM.

  39. Charles Bridge Sculptures: Description of Digitizing Process • Two integrated systems were used: • ATOS is an optical measuring machine based on the principle of triangulation. Projected fringe patterns are observed with two digital cameras. 3D coordinates for each camera pixel are calculated with high precision, and a polygon mesh of the object’s surface is generated. • TRITOP is a photogrammetry system that measures the exact position of physical markers placed on the object.

  40. Charles Bridge Sculptures: Description of Digitizing Process • Procedure: • The markers are placed on the object and some coded markers and one or two scale bars are added. • Images are taken with the digital camera from different positions. • Clouds of points from the ATOS system were registered into the predefined grid of marker points defined by TRITOP. • Evaluation software defines the exact 3D position of the center of the markers on the object.

  41. Charles Bridge Sculptures: Final Model • The final full 3D model has been produced as a rapid prototype sculpture by the Czech company, MCAE.

  42. Charles Bridge: Point cloud data to Maya to RP • Long range 3D laser scanning data courtesy GEFOS, CZ was first read into RapidForm software (.ptx format). • Modular model created in Maya from single arch data • Data triangulated and refined in Geomagic. • Final .stl file output as rapid prototyping model using Dimension BST rapid prototyping system from MCAE, CZ.

  43. Mesa Verde: Computational Archaeology • This project focuses on digital preservation and non-destructive analysis of ancestral puebloan architecture in the southwest United States. For over 100 years, research within archaeological districts such as the World Heritage site at Mesa Verde has provided valuable origin and cultural information to the current day Native American cultures, the scientific community, and the general public. • The project, in partnership with the National Park Service at Mesa Verde and discipline specialists at the Center for Southwest Studies at Fort Lewis College and Arizona State University, builds upon that significant research through the use of non-invasive laser scanning technologies and development of research tools to digitally preserve and analyze ancestral puebloan architecture and associated artifacts.
