Gauging the Repeatability of 3D Imaging Systems by Sphere Fitting

September 30, 2009
Author(s)
Marek Franaszek, Geraldine S. Cheok, Kamel S. Saidi
Multiple scans of the same object acquired with 3D imaging system (e.g., laser scanner) in the same experimental conditions could provide valuable information about the instrument s performance (e.g., stability, existence of bias, measurement error)

Target Penetration of Laser-Based 3D Imaging Systems

January 19, 2009
Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Marek Franaszek
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. The

ASTM E57 - 3D Imaging Systems

June 4, 2008
Author(s)
Geraldine S. Cheok, Alan M. Lytle, Kamel S. Saidi
As the applications for 3D imaging systems continue to grow, the need for standards to evaluate these systems has become more critical. The ASTM E57 3D Imaging committee established in 2006 was formed specifically to develop standard terminology, test

THE ROLE OF CAMERA NETWORKS IN CONSTRUCTION AUTOMATION

May 7, 2008
Author(s)
Itai Katz, Kamel S. Saidi, Alan M. Lytle
Due to the complexity and variability of capital construction sites, real-time monitoring remains an elusive goal. As unit price continues to fall, camera networks are becoming increasingly viable sensing modalities. The benefits of combining multiple

ASTM E-57 3D Imaging Systems Committee: An Update

March 19, 2008
Author(s)
Alan M. Lytle, Geraldine S. Cheok, Kamel S. Saidi
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 to

In 2006, an ASTM committee (E57) was established to develop standards for the performance evaluation of 3D imaging systems. The initial focus for the committee is on standards for 3D imaging systems typically used for applications including, but not

Evaluating a Ranging Protocol For 3D Imaging Systems

September 19, 2007
Author(s)
Geraldine S. Cheok, Kamel S. Saidi, Alan M. Lytle
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 a
