Set the 3D Scene Transform menu to Unaligned
before setting the ground plane.
Setting the Ground Plane
The Camera Tracker has no idea if the camera is on its side or tilted in some way. So, it is
up to you to indicate where the ground plane is in a clip. After choosing Unaligned from the
3D Scene Transform menu, you can begin identifying the ground plane.
Drag a selection box around marks that represent the ground.
To set the ground plane, do the following:
1 Move to a frame with lots of green 3D locators where you can see a large part of
the ground.
2 In the viewer, drag a selection box around the marks located on the ground in the clip.
3 In the Inspector Orientation section, click the Set from Selection button.
TIP: In some cases, the clip you are tracking may not have the ground in the frame.
If necessary, you can set the Selection menu to XY, which indicates you are selecting
points on a wall.
