vSite AR: QR-based Calibration

vSite uses multiple positioning methods, including using QR codes. QR code-based positioning requires an initial job site setup and calibration steps within the vSite AR app.

This article describes how to calibrate the Augmented Reality feature in the vSite AR app. To see how to set up QR Codes in the vSite Admin Portal, click this link.

QR Code-based Calibration

  1. In the vGIS AR app, click calibrate or re-calibrate. Note: Make sure GNSS connection is turned OFF.
  2. On the action bar, press QR Code.
  3. Scan your first QR Code.
  4. Proceed to a second QR code and scan it. Alternatively, you can skip this step and align the app manually by pressing “vGIS” button.
  5. Enable required layers.
  6. Your AR dataset should load. If no data appears, make sure the appropriate layers are turned ON, verify your Team/Project or check whether you have the right coordinates.
     

Position Corrections - AR Drift Compensation

When using vGIS AR app without a GNSS or Total Station, the system will accumulate "drift" - the visuals will gradually shift from their original location. To fix the drift, you can either re-calibrate (see the previous section, Steps 1-4) or fix the drift by scanning the nearest QR code. To do so:

  1. In the AR mode, press Tools and then QR Code.
  2. Scan the nearest QR Code to adjust your position.
  3. Fix your alignment using the Adjust button, if required
