Pick and mouse menus exist for each of mono, left and right Tvs. These are used to select pick and mouse activity of their respective Tv devices (see mono and stereo tools and other relevant sections of the user guide for details). They provide facilities to select, display and print edge data and geometry. Other tools (e.g. the mono and stereo tools) are also able to change these mouse and/or pick facilities. Selecting pick and mouse facilities sets the appropriate activity on the associated Tv tool is it exists.
The following pick facilities exist for each Tv device.
PICK: MONO edge: output relevant values of the selected edge. LEFT edge: output relevant values of the selected edge. RIGHT edge: output relevant values of the selected edge.
Mouse facilities are only currently implemented for left and right Tvs.
MOUSE:
LEFT
RIGHT epi: use currently defined parallel camera geometry
to compute the pair of epipolar lines (in left
and right images) that pass through the current
mouse position and draw them over the extent of
the left and right images. Uses only the left
mouse button and can be dragged (on button release
the final epipolar pair is displayed until the next
repaint call to the Tv).
rast: display the left and right image rasters (horizontal
image lines) that pass through the current mouse
position on the left and right image Tv tools. Uses
only the left mouse button and can be dragged (on
button release the final epipolar pair is displayed
until the next repaint call to the Tv). Note that
zooming/shifting of left and/or right hand Tv does
not affect the position of the raster with respect
to the underlying image (although it will shift their
position with respect to the Tv itself).
