PRO CMM with DMM

Add high-speed, real-time dynamic motion measurement (DMM) capabilities to the PRO CMM optical tracker with unique targets that track the 3D motion or 6DOF position of objects.

Overview

Capture the fast, complex motion of multiple objects over large volumes with exceptional precision using NDI’s Dynamic Measuring Machine (DMM). The NDI Dynamic Measuring Machine is one of the most powerful and capable tools for dynamic measurement and advanced motion analysis. The DMM uses an Optical Tracker to track specially designed targets that mark specific points of interest. The Optical Tracker’s most powerful feature is the unique ability to track how 3D and 6DOF measurements change over time, adding a new dimension to industrial metrology by allowing for motion tracking and dynamic measurement.

Tracking System

DMM adds dynamic motion measurement capabilities to the base PRO CMM system, combining best-in-class 3D and 6DOF dynamic tracking and portable optical coordinate measurement, for advanced real-time metrology and motion analysis.
