## What is Calibrator Pro?

NOTE: This application is designed for the Structure Sensor accessory.  Learn more at http://structure.io

Refine your Structure Sensor's full potential with Calibrator Pro!

This is a paid app that enables trained users to calibrate the intrinsic parameters of their Structure Sensor.

Users need to contact Structure (XRPro LLC) to obtain a calibration target. The target includes a QR code that informs the app about specific characteristics of each board. As such, users should never use copies of existing boards.

The app requires training and, if misused, could result in the deterioration of the calibration of a  sensor. Once trained, operators are expected to be able to complete a sensor calibration in 3-5 minutes.

This app does not replace the standard Calibrator app (Used to calibrate the extrinsic parameters between a Structure Sensor and the main camera of the iOS device.)

This app uses in-app payment. Users have the option to pay to calibrate a single sensor, or you can receive a discount when buying multiple calibrations in bulk. Once a sensor is calibrated, it can be re-calibrated multiple times the same day, free of charge.
