System Calibration

Before using AR 51, complete camera calibration, capture-area calibration, and device calibration — this aligns the cameras, VR devices, and the physical capture space into one synchronized coordinate system. The process has three stages:

• Camera calibration

• Capture-area (bounding box) calibration

• Device calibration (VR headset alignment)

By the end of this section your cameras, VR devices, and capture space will share one synchronized coordinate system.

Camera Calibration

The first step involves setting up and calibrating the cameras to ensure they accurately capture and interpret the physical space. It includes:

• Calibration board detection

• Lit calibration sphere detection

Bounding Box Calibration

Next, define the capture-area bounding box so AR 51 knows the physical limits of the performance space. A correct bounding box ensures the system captures only within the intended volume. This step focuses on:

• Setting the center and dimensions of the bounding box

• Sending the bounding box data to the server

• Validating the bounding box calibration

VR Device Calibration

Here, we will calibrate the VR devices to ensure they are synchronized and functioning correctly within the capture environment. This includes:

• Ensuring all devices agree on a common coordinate system

• Moving and positioning your hands within the VR environment for accurate tracking

LED Stage Synchronization

Here, we will sync between an LED stage coordinate system and AR 51's coordinate system by projecting the checkerboard pattern onto the LED floor.
