Locking onto 3D-structure by a combined vergence- and fusion system

An interacting fusion and vergence system is presented which utilizes two properties of coherence-based stereo: sub-pixel-precision and a stable validation signal for disparity estimates. This allows the system to sample the three-dimensional scene with several precisely chosen fixation points and automatically accumulate the data into a full disparity map. In addition, the system creates a fused cyclopean view of the scene, co-registered with the final disparity map.
