Before You Begin
Load an XR View.
You will be prompted to:
Scan the environment until valid planes are detected. Planes can be vertical or horizontal and are displayed as semi-transparent dots.
Tip: Point your device towards the ground and move it slowly in a sweeping motion until a ground plane is detected.
Select a calibration method:
Image Target
Manual Calibration
Two-Point Calibration
Image Target Calibration
The calibration method uses printed image targets to align the virtual reference frame with the physical world at pre-defined locations. Image Target locations are configured and published from Tobe Builder as part of the XR View publish process. The universal Image Target used by TobeMaps can be downloaded from Tobe Builder and must be printed in A4 Portrait without any scale modifications in order to work correctly with TobeMaps.
To complete calibration using Image Target, follow the steps below:
Select Image Target from the calbration options.
Scan the image target until it is detected and 100% tracking confidence is reached (you can proceed with less than 100%).
Known Bug: TobeMaps v1.7.1 does not display the Tracking Accuracy UI (label and coloured focus area does not turn on)Press Next
Available Image Targets are shown as dots on the map. Select the required Image Target using one of the following methods:
Tap on available Image Targets directly on the Map. This will select the target and show its name.
Press the QRCode button
to show a searchable list of available Image Targets. Select a target from list by tapping on the target name.
Press Next
to complete calibration.Turn BIM's on using the Visibility Panel or BIM Hierarchy
Manual Calibration
Ideal when image targets are unavailable. Align using GPS and manual adjustments.
Steps:
Select Manual Calibration.
Set Position:
Tap on the map or relative to a model.
Drag to set your current position on the Map
Press GPS button to set position to current GPS position
Set Rotation:
Screen splits into two views.
Align the map/model with a known physical feature in AR View.
Pinch to zoom; drag to rotate.
Set Elevation:
Screen splits into two views.
Drag in AR View to adjust model height.
Manipulate map view as needed.
Two-Point Calibration
Provides the highest accuracy when Image Targets are not available by aligning two points in the virtual world with two points in the real world.
Steps:
Select Two-Point Calibration.
Pick 2 Points on Map/Model:
Navigate to the required location on the Map or in your BIM
Long press to place first point.
Long press to place second point.
Accurately adjust created points by long pressing and dragging on the required point if necessary.
Press Next.
Scan Environment to detect planes.
Align Points in Real World:
Align reticle with real-world location for first point, press the Anchor button.
Repeat for second point.
To edit, hover reticle over a point and press the Edit button. Reposition the point and press the Anchor button to lock the point in place.
Press Next to finalize calibration.
Tips for Best Results
Ensure good lighting and clear visibility of physical features.
Move slowly and point you device towards the ground while scanning for better tracking confidence.
Use Two-Point Calibration for accurate calibration when Image Targets are not available.
