The 3DIS System
S. Veitch, J. Dexter, G. Ross, Joseph Driscoll, Melissa Watts · 2002
The 3DIS Security System uses the overlapping fields of view of multiple video cameras to create discrete 3D volumes of space that are sensitive to movement. The system may be used in both indoor and outdoor installations to implement automated video surveillance. 3DIS Version 1.xx has validated the use of "3D detection zones" within the security industry. 3DIS Version 2.xx is nearing the end of the first stage of its development.
