I.5 Depth Map (Stereo 3D video only)
The Depth Map uses colour to show how far the various features in the current Stereo 3D image
are away from the viewer.
The map is created by colouring each pixel for which the OTR determined the disparity. Points
at which the disparity was found to be less than or equal to the Minimum Budget disparity are
coloured red; points with disparities greater than or equal to the Maximum Budget disparity are
coloured violet; and points between are coloured using the standard colour ramp. The proportion
of points for which the disparity was outside the specified limits is listed in the Status display
(see Section E.6).
Two versions of the Depth Map may be shown: one in which all the points for which disparities
were determined are displayed; and another – the Depth Error Map –which just displays the
points that were outside the specified Depth Budget. A further option is to display the scene for
which the disparities were determined as a greyscale image behind the Depth Map.
