Physical Camera and Hero Tracker Offset Setup

Section 12.1 Physical Camera and Hero Tracker Offset Setup

The Camera Offset function allows you to change the settings inside Unreal Engine 5.3 or 5.4 in order to match the physical distance between the physical camera sensor and the hero camera tracker.

Important

This is not always necessary, but if there are perceived issues in parallax or scale when in play mode, the camera offset should be adjusted. Accurate recordings help the virtual and real environments to match. If there are no perceived issues, then these settings can be left alone.

1. Set up physical camera hero tracker offset to match in Unreal Engine.

2. Match the virtual ARwall Camera Actoroffset to match the physical camera hero tracker offset.

3. Measure the vertical (up/down, X-axis), depth (forward/backward, Z-axis), and side-to-side (left/right, Y-axis) physical distance in centimeters from the physical camera sensor to the bottom/center of the physical Vive hero tracker.
   

   

   Important

   • A physical camera’s sensor’s depth is often represented by a focus puller hook. Make sure to account for the sensor depth when measuring for the x-axis offset.

4. Follow the examples displayed in the image below to offset correctly. Left offsets negatively, right offsets positively.
   

   

5. Input the X, Y, and Z-axis values determined from physical measurements into ARwallCameraActor > OffsetComponent > Transform > Location’s X, Y, and Z-axes.
