XR - Calibration procedures

Calibrate your XR Studio

XR calibration needs a specific XR/AR license. If you’d like to try out these features to decide whether you want to purchase an XR/AR license, please contact us.

The calibration procedures aim to ensure a cohesive image while doing virtual production and set extension, by establishing a visual bridge between the real world (captured by the camera) and the virtual world (generated by Smode). It is considered the most critical aspect of XR projects.

To initiate the calibration process, ensure you have a Video Input connected to the input camera device.

In the Stage , click on the XR Calibrator icon on the Physical Camera .

In the XR Calibrator window, select the right Video Input and point the camera at the LED screens.

Ensure your Physical Camera is within a Stage Elements Group and set the appropriate resolution in the Group’s parameters to match the real camera device. Also, ensure that you follow the correct layer order as explained in the topic: Camera Tracking .

There are three different calibrators:

• XR - Latency Calibration : Automatically assesses the frame delay between sending an image to the LED screens and receiving it back through the camera.

• XR - Geometry Calibration : Adjusts the placement of the Tracking System , corrects the position of the Tracker and modifies the Camera Model of the Physical Camera .

• XR - Color Calibration : Generates a Lookup Table (LUT) that can be applied later on the set-extension with a Smart Lut .

It’s important to follow the order of these calibration steps. The Geometry calibrator relies on information from the Latency calibration. Then, the Color calibration needs the information provided by both the Geometry and Latency calibrators.

Therefore, the calibration must be done in the following order:

1. Latency
2. Geometry
3. Color

Before proceeding with the calibration, we recommend reviewing the topic: Sanity Check for XR setup .
