EZlineup

Intelligent camera offsets calibrator

Universal workflow for highly accurate camera line-up in minutes, regardless of camera, optic, or tracking system.

EZlineup takes advantage of Miraxyz’s proven computer vision techniques to ensure precise alignment and spatial consistency for any tracked camera. Whether using optical or mechanical-based tracking, our solver provides a universal workflow for computing offsets!

Automatic Offset Measurement

Enhanced Spatial Consistency

Versatility and Flexibility

Why Camera Lineup appears so important?

While manual offsets measurement using a tape measure or laser remain feasible, accurately estimating tiny rotational angles in degrees can be quite challenging for any camera operator. This manual process remains time consuming and often yields satisfactory results from a specific viewpoint. However, when the camera shifts to a different perspective, spatial discrepancies may reappear, compromising the consistency of the effect. This is why Miraxyz developed EZlineup!

Achieving pixel-perfect image compositing that seamlessly integrates the virtual layer often requires the operator to finely adjust the camera tracking system. This involves measuring the offset distance between the tracking sensor or marker and the camera’s CCD sensor, thus correctly aligning the tracking origin point of the stage with the camera setup.

Using our tag-based pattern “MAGIC CUBE” placed at the stage’s origin reference and captured by the camera from multiple viewpoints, EZlineup integrates the live FreeD tracking data flow with an accurate lens profile generated by our patented lens profiler into a computer vision-based solver. The recorded data is then automatically processed to deliver precise alignment and spatial consistency.

Studio Calibration Bundle

The Studio Calibration bundle comes with all the licenses and calibration equipment to implement EZlineup and EZprofile into your pipeline, including:

1 x EZlineup perpetual seat license for 1 single PC
1 x EZprofile perpetual seat license for 1 single PC
1 x separate hard-printed “Magic Cube” calibrator
1 x premium set of 4 aluminum calibration boards

Achieve Accurate Referentials for Your Stage…

The Referential Offset Transform is the offset of the tracking referential in the cube referential.
It can be used to:

Define a new origin in a better location
Share the same origin across multiple systems
Refine the tracking referential to perfectly align a virtual object with the real world

…and Precise Camera Line-Up

EZlineup aims at automatically measuring
two distinct offsets between:

The sensor plane of your camera and the tracker (Camera transform)
The origin point of the studio and your camera (Device transform)
