A stereo image pair along with the appropriate camera calibration is read into Tina via the Stereo Tool. Regions of interest are setup via the or read in via Read roi, these will define the subsequent working area within the image pair. The images are transformed to cyclopean co-ordinates and edges detected (see the Edge Geom Tool). The following minimal button sequence must then be used:
This process is an alternative to using the default stereo matcher (stereo). The resulting matches can be used to determine quantitative 3D measurement using the geom3 button and associated functions (see below).
