Moiré Phase Tracking (MPT) technology provides true 3D from a single camera

May 30, 2013 in Uncategorized by admin

Metria Innovation’s unique Moiré Phase Tracking (MPT) technology provides true 3D measurement using a single camera in cooperation with highly engineered markers.  Each marker provides accurate measurement data for position (X, Y and Z) and orientation (Pitch, Yaw and Roll).  Accuracy for position is better than 1.0mm RMS at 2.5 meters with class leading orientation accuracy of better than 0.05 degrees RMS for marker pitch, yaw and roll.

Please have a look at our products, and know that we are always interested in applying MPT to new and interesting applications.  Don’t hesitate to call and ask us what MPT can do for you.

Motion Capture and Motion Tracking demonstrations.

May 15, 2013 in Uncategorized by admin

Moiré Phase Tracking (MPT) has a multitude of uses.  Precise measurements are taken from the unique optical moiré phase patterns.  MPT has found application in MR imaging, Biomechanics, Virtual Reality, Dynamic Testing and Surgical Guidance.  True 3D with a single camera allows the MPT system to come to the subject’s location.  MPT has angular accuracy up to 30x higher than comparable 10 camera systems.  The markers used each have a unique identification code, allowing up to 256 uniquely identifiable markers in a single scene.  Our MPT markers can be robustly identified even within images of complex scenes.

High Sensitivity Measurements with Moiré Phase Tracking

April 30, 2013 in Uncategorized by admin

This demo shows the sensitivity of the MT384ib. You can read the measurements as they go by, noting the sub-millimeter accuracy.

The Metria Innovation MT384ib High-field Motion Tracking System.
This system is capable of tracking a marker at 84 measurements per second.
Measurements provide both positional information (x, y, z), and orientation (pitch, yaw, roll).
Positional measurements have less than 0.1mm RMS error.
Orientation measurements have less that 0.05deg RMS error.

Moiré Patterns are Highly Sensitive to Out of Plane Rotations.

April 30, 2013 in Uncategorized by admin

One of Metria Innovation’s 65mm MPT markers.

This is a demonstration that even small movements in the orientation are amplified by the changes in the moiré patterns, leading to extremely accurate orientation information independent of marker camera separation.
