Critical Issues　of current 3D images
3D middle/long-range shooting, especially over 10m, may be Really incomplete 3D, troublesome and complicated task?

■Less attractive 3D contents in long-distance scenes
To avoid extreme parallax and negative checks about safety , the shorter interaxial distance (base-line) of shooting, the more loss of 3D effects.

■Due to geometric distortion, eyes are prone to be strained
Manual mechanical rig, especially in a long distance, the vertical and keystone distortion is a frequent cause of incomplete 3D images and eyes strain.

■Need long time for 3D shooting and extreme high cost
・Require specialists called a stereographer.
・Take long time a proper calculation of shooting distance and rig adjustment based on experience.
・High-cost of large-scaled equipments and manpower expenses as for 3D shooting.



■Optimum Interaxial Distance Model
we developed optimum interaxial distance(IAD) model to calculate best IAD  automatically which can get optimum 3D against target and satisfy safety guide(within 3%) concurrently. Its model can generate complete 3D scenes of long-distance objects without cardboard effect by automated-adjustment of IAD.

■Standard Vergence Model
As standard vergence model keeps relative position of space correctly like human eye, it is possible to control alignment justly and convergence between camera with consistency.


■Bionics & Binocular Control Model
Human eyes have their own cooperative movements;
Binocular cooperative movements, Saccade, Smooth pursuit, vestibulo-ocular reflex(VOR), Cervico-ocular reflex(COR).
With this binocular motor model based on the human neural pathways, we implemented an unique 3D shooting system close to human binocular system.
