31. Target Penetration of Laser-Based 3D Imaging Systems
Published: 1/19/2009
Authors: Geraldine S Cheok, Kamel S Saidi, Marek Franaszek
Abstract: The ASTM E57.02 Test Methods Subcommittee is developing a test method to evaluate the ranging performance of a 3D imaging system. The test method will involve either measuring the distance between two targets or between an instrument and a target. Th ...

35. ASTM E-57 3D Imaging Systems Committee: An Update
Published: 3/19/2008
Authors: Alan M. (Alan M.) Lytle, Geraldine S Cheok, Kamel S Saidi
Abstract: In 2006, ASTM committee E57 was established to develop standards for the performance evaluation of 3D imaging systems. The committee's initial focus is on standards for 3D imaging systems typically used for applications including, but not limited t ...

37. Fast automatic registration of range images from 3D imaging systems using sphere targets
Published: 1/1/2008
Authors: Marek Franaszek, Geraldine S Cheok, Christoph Johann Witzgall
Abstract: 3D imaging systems are line of sight instruments and multiple scans from different locations are often needed to get a good representation of an entire scene. Therefore, registration of different datasets to a common coordinate system is required. A ...

38. Evaluating a Ranging Protocol For 3D Imaging Systems
Published: 9/19/2007
Authors: Geraldine S Cheok, Kamel S Saidi, Alan M. (Alan M.) Lytle
Abstract: In 2006, the ASTM E57 committee was established to develop standards for 3D imaging systems. A 3D imaging system is a non-contact instrument that is used to measure the range and bearing to and/or the 3D coordinates of points on an object or within ...
