vSite Admin Portal: QR-based Calibration Setup

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.

Note: vGIS does not require updating original models with QR codes - QR codes within vSite are independent from the model.

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.

Site Setup

1. Identify a few points around your job site. These points can be located on walls,, floors or ceilings and should be safe to access. In the area where users begin using vSite AR, you need two points 5-7m/15-20ft apart. Other points can be spaced 20-25m/60-100ft throughout the job site.
2. Record the Latitude/Longitude/Elevation or X/Y/Z coordinates of designated points. The type (Lat/Long/Elevation or X/Y/Z) is determined by the data set you intend to use. If you intend to use the dataset in Global Coordinate System (e.g., with GNSS), use Lat/Long/Elevation. For datasets that exist in Site Coordinate System only, use X/Y/Z.
   • The points can be measured with a total station or GNSS.
   • Alternatively, you can pick such point from your model if you know the exact physical location of each point in the model.
3. Navigate to the vGIS QR Code Generator. It can also be accessed on the vGIS website (www.vGIS.io) under, QR Code Generator in the footer section.
4. Enter either Local or Geographic coordinates for a point, using the toggle at the top of the screen to switch between the two and click Generate.
5. Print or Download the generated code.
6. Repeat steps 4 and 5 for all designated points on the job site.
7. Place printed QR codes over the physical points. The point should be in the middle of the QR code.

Tip: you can use the "Note" field on the QR generation form to add notes to your QR codes to simplify their management.
