Perception Systems
The Perception Systems Group is part of the Intelligent Systems Division in the Manufacturing Engineering Laboratory (MEL) at the National Institute of Standards and Technology (NIST). The group specializes in performance evaluation and metrics for perception systems used for manufacturing, mobile robots, and robot safety. Tools used include highly accurate laser measurement systems, large scale field trials, and an industrial robot test bed. The work has applications in factories for assembly and material handling, in transportation for navigation and safety, and in the military for autonomous vehicles.

Researchers developed a procedure using a dynamic, six-degree-of-freedom (6DOF) laser tracker to evaluate the performance of a real-time visual servoing implementation for on-the-fly assembly. The objective of the study was to establish a general method for evaluating real-time 6DOF dimensional measurements of moving objects. The evaluation procedure collects data simultaneously from the laser tracker and the visual servoing system under test so the two data streams can be compared. Laser trackers produce highly accurate position and orientation data at a high data rate and can therefore be considered to provide ground truth. Statistical comparisons were made on a number of scenarios to determine the performance of the visual servoing system.
