I.6 Depth Plan (Stereo 3D video only)
The Depth Plan provides various views of the depths determined from the Stereo 3D right- and
left-eye images. These include views as if you were looking down on the scene from above or
from the side and a projection that can be viewed from all different angles. All the positions are
determined as for the viewer i.e. in Viewer World coordinates.
The view from above is referred to as the Viewer World (Plan); the view from the side is
referred to as the Viewer World (Elevation). The third display is referred to as the Real World
Projection.
The Depth Plan can also be set to show a ‘Disparity View’ in which the disparity values
determined from the images are mapped across the width of the screen.
Superimposed on all four plots are lines/planes representing the screen plane and the limits of the
specified Depth Budget. On three of the displays, there is also the option of a read-out of the
Viewer World coordinates of the point at or nearest to the current crosshair position.
Viewer World (Plan) view
Figure I-10: Viewer World (Plan) view.
The Viewer World (Plan) view is an x , z plot of the positions determined for the current image.
This presents the depth information as if looked at from above.
The range of depths displayed can be adjusted by setting the Zoom level in the Properties control
(see ‘Display Properties’ below.)
Note: The display is limited to items within the field of view captured in the image. As a result,
the points shown all fall within a cone spreading out from the viewer’s position at the tip of
the cone.
Note also that clicking on the display with a mouse will normally select the nearest point at
which the disparity has been determined. However, if required, you can select a point on the
x , z plane ( x , 0, z ) by clicking (or clicking and dragging) while holding down the Ctrl key.
