| Vitrius, for military training in an urban environment the video-based identification and positioning system - works day and night, indoors or outside - no batteries, no RF transmission - high accuracy, low system latency - scalable from squad to battalion level - sensors easily installed and relocated - data collection and presentation can be tailored to the exercise |

The Vitrius from Tenetec is a novel and costeffective positioning system that
is suitable for both internal and external use in urban combat arenas. Based on advanced video
processing and pattern recognition,the system typically uses one or two sensors to cover an
average-sized room, giving position updates with centimeter accuracy in the
x, y and z axes, in real time. Despite this remarkable accuracy, the
Vitrius is an extremely economical system to buy and to operate: unlike other 3D tracking
systems, the Vitrius does not rely on triangulation and can therefore provide accurate 3D
positioning using a single, commercially available sensor. |

|
| The Vitrius features industry-standard interfaces and protocols, and
is quickly installed with only a minimal infrastructure. It can locate and identify not only
soldiers but also vehicles and heavy weapons, and can be used to provide positional information
for furniture, doors, blowholes, and other moveable exercise-relevant objects. |

Completely passive, lightweight tags are used to identify exercise participants, so
battery management does not become an issue and more importantly, the solution does not add
unduly to the participants weight burden. The Vitrius urban environment is divided into
Data Capture Zones, each of which has a single video camera. Depending on the type of exercise, the
Data Capture Zones may be set up to overlap (two in a room), to cover a pathway throughout
a building (four per building), to track movements at intersections (one per intersection), or
in any combination of the above. Since the installation and calibration of additional Data
Capture Zones can be done within an hour or so, the Vitrius can be tailored to provide the
level of information required for the training being conducted. Thus a system with 400 Data
Capture Zones that supports exercises at the company level is also useful for individual and
battalion-level exercises. |
|
| Prior to the exercise, participants (personnel, vehicles, weapons, movable
furnishings, blow holes etc) are fitted with a passive, individually coded identification
tag that is linked to corresponding object properties within a central database. Object properties
include general information about the object type such as appropriately scaled icons as well
as specific information about the individual object which has been supplied in electronic
format prior to the exercise (name, rank, serial number for a person, for example). |
|
 |
|
| As participants enter the Vitrius environment, the tags they are wearing are
visually captured and decoded, and the x-, y-and z-coordinates of the tag are calculated. Tagged
position updates are transferred via LAN to the Data Management Module at the EXCON where
they are made available in near real time for exercise monitoring, and can be included at any
level of detail in After Action Reviews. The information, displayed in a calibrated 3D representation
of the exercise area, can be viewed as is for squad training or aggregated to provide an overview
of the exercise for platoon or company training. Bookmarks can be established during the exercise
to facilitate the preparation of After Action Reviews. |
