Version: Traxis Camera Tracking 2.3

Device Transform (PTZ)

PTZ cameras do not have built-in location tracking. Therefore, their position in studio space must be manually defined.

First Approach – Less Accurate​

A simple method is to manually measure the X, Y, and Z coordinates of the PTZ camera and enter them under Device Position and Device Rotation.
While this provides a reasonable approximation, it is often difficult to measure pan, tilt, and roll angles accurately.

Device Position and Rotation

Second Approach – More Accurate​

A more precise method relies on the distance between the studio origin (on the ground) and the pivot point of the PTZ camera.

  1. Fix the camera position: Place the PTZ camera in its final position and avoid moving it afterward.
  2. Measure pivot-to-origin distance: Measure the distance from the camera’s pivot point to the studio origin on the ground as accurately as possible.
  3. Align using CrossHair: In Traxis Hub, activate the CrossHair and use the camera’s PTZ controls to center the origin point (0, 0, 0) in the exact center of the camera image.
  4. Enter placement data: Input the measured distance into the Place Origin box and click From Center.

Place Origin Settings

  1. Confirm grid position: The studio grid should now move to align with the origin.

Grid at Origin

  1. Check coordinate values: Review the X, Y, and Z values. The Y coordinate should represent the height of the camera pivot above the studio floor.
  2. Validate height consistency: If the measured pivot height matches the Y value, setup is complete.

Device Position Values

  1. Adjust values if needed: If the values differ, enter the measured pivot height manually into the Y coordinate of Device Position. Then, use the Advanced Placement Tools to adjust the virtual origin to match the real studio origin.

Advanced Placement Tools

  1. Refine rotation alignment: When the origins overlap, fine-tune alignment using Device Rotation (Pan, Tilt, Roll) controls to match the virtual grid with the physical studio coordinates.

Device Rotation Alignment

  1. Iterate until accurate: Repeat position and rotation adjustments until the virtual and physical setups are fully aligned.
