Introduction

The Edge Geom Tool is an interface to those routines in the Tina system for performing edge detection and subsequent pre-processing for stereo and the recovery of 2D scene descriptions (There are significant changes between this tool and the largely equivalent Edge Tool which was in version 4.0).

Two processing modes are available, "mono" and "stereo" ; these relate to the mono and stereo management tools discussed in section 2 of the user guide .

Menus for controlling the Pick and Mouse facilities of associated Tv devices are provided. In addition "pop up" dialog boxes allow various default parameter settings to be manipulated.

Edge data and the 2D geometry recovered from it is now always displayed and manipulated (using the mouse) in real image coordinates even when the edges themselves have been rectified into the equivalent camera coordinate frame (recovered using calibration data).
