Pick and mouse menus exist for each of the mono, left, right and threed Tv tools. These provide facilities to select, display and print corner data and geometry. Other tools (eg mono and stereo) can also modify these facilities.
The following pick facilities exist for each Tv device
MONO corner : output measured parameters of selected corner. c match : display selected matched corners. LEFT corner : output measured parameters of selected corner. c match : display list of candidate matches for selected corner. RIGHT corner : output measured parameters of selected corner. c match : display list of candidate matches for selected corner. THREED print : print measured parameters of selected geometric feature. choose : keep selected geometric features. delete : delete selected geometric features.For the stereo left and right Tv tools the corner option, when used in conjunction with the middle mouse button, will add the most recently selected pair of selected corners into the stereo corner matching data structure thus facilitating the possibility of manual matching for difficult scenes or scenes without a good initial calibration.
Mouse facilities are implemented for left and right Tv's.
LEFT RIGHT epi : use currently defined parallel camera geometry to compute the pair of epi-polar lines that pass though the current mouse position and draw them over the extent of both images. Uses only the left button which can be dragged. Lines displayed on release remain until a redraw. rast : display the left and right image raster at the current mouse location.
