General Configuration • Optical axes • Meet at fixation point, P • Have angle between them • CFoV has arbitrary shape
Canonical Configuration Scene object FoV (single camera) Closest point of CFoV (Half)Angular FoV Optical centres Image of scene object Baseline
Field of view – Verging axis FoV (single camera) Scene object (Half)Angular FoV Optical centre
Common Field of View – Verging axes Fixationpoint Limit of CFoV = 0 > 2 = 2 (Canonical config)
