Performance Evaluation of 3D Imaging Systems

摘要

Recently, the National Institute of Standards and Technology, as the United States' primary measurement laboratory, launched an assessment of the U.S. Measurement System. The aim is to determine whether this vital infrastructure can effectively address multiplying needs for evermore exacting and reliable measurement tools and associated services. The development of standard test methods for three-dimensional imaging systems is a recognized USMS need. The FIATECH consortium has also recognized this need and, in partnership with NIST, has established the Laser Scanning Measurement Assurance Project. Although the technology for most 3D imaging systems has existed for several decades, the use of these systems has become more established or accepted only in the past 10 years. 3D imaging systems are used to rapidly capture, in thousands of measurements per second, 3D information on a scene or object. Systems include laser scanners, LADARs (laser detection and ranging), laser radars, 3D range cameras, and 3D flash LADARs. The applications for 3D imaging systems span widely varying industrial and government sectors such as construction, manufacturing (e.g., aerospace and automotive), homeland security, military, law enforcement (e.g., forensics), and transportation safety, and they continue to grow. In the construction industry, the anticipation is that these systems will eventually either replace or merge with total stations (survey instruments that measure distances and angles).
