Highlights

Measuring the performance of a visual servoing system as it orients a robot manipulator relative to a moving part.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.
