The NIST Construction Metrology and Automation Group (CMAG), in cooperation with the NIST Intelligent Systems
Division (ISD), is developing performance metrics and standard tests for the evaluation of 3D imaging systems used in
autonomous mobility applications. This work supports the broader effort to develop open, consensus-based
performance evaluation standards for a wide range of 3D imaging systems and applications through the ASTM E57
Committee on 3D Imaging Systems. This report presents initial efforts to characterize the range performance of a 3D
imaging sensor that will be used in a performance measurement system for crash prevention and safety systems. Factors
examined include range, target reflectance, target angle of incidence, and sensor azimuth.
The National Institute of Standards and Technology (NIST), under an interagency agreement with the United States
Department of Transportation (DOT), is supporting development of objective test and measurement procedures for
vehicle-based warning systems intended to warn an inattentive driver of imminent rear-end, road-departure and lane-change
crash scenarios. The work includes development of track and on-road test procedures, and development of an
independent measurement system, which together provide data for evaluating warning system performance. This paper
will provide an overview of DOT's Integrated Vehicle-Based Safety System (IVBSS) program along with a review of
the approach for objectively testing and measuring warning system performance.
The National Institute of Standards and Technology (NIST) is participating in the Department of Energy Technologies Enabling Agile Manufacturing (TEAM) program to establish interface standards for machine tool, robot, and coordinate measuring machine controllers. At NIST, the focus is to validate potential application programming interfaces (APIs) that make it possible to exchange machine controller components with a minimal impact on the rest of the system. This validation is taking place in the enhanced machine controller (EMC) consortium and is in cooperation with users and vendors of motion control equipment. An area of interest is motion control, including closed-loop control of individual axes and coordinated path planning. Initial tests of the motion control APIs are complete. The APIs were implemented on two commercial motion control boards that run on two different machine tools. The results for a baseline set of APIs look promising, but several issues were raised. These include resolving differing approaches in how motions are programmed and defining a standard measurement of performance for motion control. This paper starts with a summary of the process used in developing a set of specifications for motion control interoperability. Next, the EMC architecture and its classification of motion control APIs into two classes, Servo Control and Trajectory Planning, are reviewed. Selected APIs are presented to explain the basic functionality and some of the major issues involved in porting the APIs to other motion controllers. The paper concludes with a summary of the main issues and ways to continue the standards process.
