Patented Moiré Phase Tracking technology provides true 3-D with a single camera

April 30, 2013 in Uncategorized by admin

Metria Innovation is home to the unique Moiré Phase Tracking (MPT) single camera measurement system.  Our MPT technology can provide, with a single camera, not only true 3-D measurements but also the full orientation measurements of pitch, roll and yaw.  MPT is currently used in applications that have position accuracy with less than 0.1 mm RMS error and angular accuracy with less than 0.1 degree RMS error.

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.

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 86 measurements per second.
Measurements provided both positional information (x,y,z), and orientation (pitch,roll,yaw).
Positional measurements have less than 0.1mm RMS error.
Orientation measurements have less that 0.1deg RMS error.

Moiré Patterns are Highly Sensitive to Out of Plane Rotations.

One of Metria Innovation’s 65mm 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.

Moiré phase tracking (MPT) has a multitude of uses.  Precise measurements are taken from the unique optical Moiré phase patterns.  MPT is seen in applications such as MR imaging, as well as Biomechanics.  True 3-D with a single camera allows the MPT system to come to the subject’s location.  MPT has angular accuracy up to 30x higher than 10 camera system.  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.
