NIST Workshop Series on Performance Evaluation of 3D Imaging Systems
3rd NIST Workshop on Performance Evaluation of 3D Imaging Systems
Location
National Institute of Standards and Technology (NIST)
100 Bureau Drive
Building 101, Lecture Room D
Gaithersburg, MD 20899.Date
March 2-3, 2006
Background
Two 3D Imaging Systems Performance Evaluation Workshops have been held at the National Institute of Standards and Technology (NIST) – the first in 2003 and the second in 2005. These workshops were conducted in an effort to determine the need for standard test methods for evaluating a 3D imaging system (previously referred to as LADAR), to determine the types of measurements and test methods required, to provide a forum to discuss the on-going efforts in this area, and to initiate the process towards standardization of these test protocols.
Although the technology of many of these systems has been around for some time, the use of these instruments, has only started to become more established and accepted in the past 10 years and is still considered an emerging technology in most industries. In this same time span, 3D imaging technology has also undergone significant advancements. However, there are no standard test protocols for evaluating the performance of ground-based 3D imaging systems such as laser scanners, 3D range cameras, and flash LADAR (laser detection and ranging) instruments and methods for assessing the accuracy of the derived output such as 3D models, volumes, or geometric dimensions.
Based on the input from the first two workshops, NIST has initiated the development of a small indoor artifact-based test facility for evaluating 3D imaging systems; developed a pre-standard document of terminology for 3D imaging systems; and drafted a pre-standard test method for determining range uncertainty.
To continue the effort towards determining performance requirements and developing test methods for performance evaluation of 3D imaging systems, NIST is conducting a 1-1/2 day workshop to solicit comments and input from instrument manufacturers, end-users, and researchers on the draft terminology and the draft protocol for range uncertainty.
The objectives of this third workshop are to:
Select a standards developing organization (SDO) to house the test methods for 3D imaging systems.
Finalize the Terminology Pre-standard
Finalize the Range Uncertainty Pre-standard
