Show stereo pair

with stereoscope

Show a calculated stereo pair in a Stereoscope window; you will be able to view the height differences in the stereo pair by using a stereoscope that is mounted onto your monitor.

To create a stereo pair:

use the Epipolar Stereo Pair operation, or
use the Stereo pair from DTM operation.

To start showing a stereo pair with a stereoscope:

When creating an epipolar stereo pair:

close the Epipolar Stereo Pair - Creation window with the Exit and Show button , or

When a stereo pair already exists:

from the Operations menu of the Main window, choose Visualization, Show Stereo Pair with Stereoscope, or
in the Operation-list, double-click the Stereoscope item, or
in the Operation-tree, expand the Visualization item and double-click the Stereoscope item, or
double-click a stereo pair in a Catalog, or
click a stereo pair in a Catalog with the right mouse button and choose Visualization, Stereoscope from the context-sensitive menu.

In case 2, 3, and 4, first the Open Stereo Pair dialog box will appear:

Select a stereo pair.
The stereo pair (and its output maps) will automatically be calculated from the input maps if the stereo pair was not yet calculated.
The stereo pair will then be shown in a Stereo Pair - Stereoscope window.

In case 1, 5 and 6, the stereo pair will directly be opened in the Stereo Pair - Stereoscope window.

Tips:

To view a stereo pair in the Stereoscope window, the output maps calculated by the stereo pair may have the Color domain, the Image domain or any other value domain.
As the output images of a stereo pair may have a very large file size, it is advised to create Pyramid Layers for both output raster maps. This will speed up display in the Stereo Pair - Stereoscope window.
The default Open behaviour for a stereo pair, i.e. open in Stereoscope window or open as Anaglyph, can be defined in the Preferences, section Main window.

Stereo Pair - Stereoscope window:

The stereo pair is shown in a Stereo Pair - Stereoscope window:

the left-hand pane of this window displays the left-hand output map of the stereo pair,
the right-hand pane of this window displays the right-hand output map of the stereo pair.

A stereoscope has to be mounted onto your monitor.

Refer the topic on the Stereo Pair - Stereoscope window for information on:

how to size the window in order to properly view the area with overlap in stereo,
how to add a georeference to one of the maps,
how to add a point map or a segment map to the stereo pair (screen digitizing).

Tip: A stereo pair can also be shown as an Anaglyph in a map window.

Additional information:

A Stereoscope window is split into two panes. You should position the window in such a way that the splitter is in the middle of your stereoscope.
Initially, the horizontal offset between the rotation points of the photographs is equal to the width of each pane. This offset will be maintained during zooming, scrolling and panning.
You may have to resize the window for proper stereo vision; by resizing the window, the horizontal offset between the rotation points of the photographs will change.
You can further adjust stereo vision by unlocking the horizontal scroll.
