System and method for forming optimized perimeter surveillance
First Claim
1. An apparatus for enabling a user to generate a virtual tripwire through a geographic area of interest using a plurality of sensors, the apparatus comprising:
- a software module adapted to run on a processor and configured to receive;
an input for allowing a user to input a digital elevation model (DEM) of the area of interest; and
an input responsive to a user controlled device for defining a swath of the area of interest, the swath representing a subregion laying over, or adjacent to, a border to be monitored; and
a display for receiving information output from the software module and displaying computed locations of a plurality of independent sensors used to form the virtual tripwire through the swath of the area of interest in a manner that minimizes the number of sensors selected to form the virtual tripwire.

Abstract
A software module apparatus for enabling a user to generate a virtual tripwire through a geographic area of interest using a plurality of sensors. The apparatus may make use of an input for allowing a user to input a digital elevation model (DEM) of the area of interest. An input responsive to a user controlled device may also be used for defining a swath of the area of interest, the swath representing a subregion laying over, or adjacent to, a border to be monitored. A display may be generated for illustrating computed locations of a plurality of independent sensors used to form the virtual tripwire through the swath of the area of interest.

15. An apparatus for enabling a user to generate a virtual tripwire through a geographic area of interest using a plurality of sensors to detect the presence of an object or individual that crosses the virtual tripwire, the apparatus comprising:
-
a software module configured to run on a processor for receiving; an input for allowing a user to input a digital elevation model (DEM) of the area of interest; and an input for enabling the user to define a plurality of candidate sensors that represents a maximum number of sensors that may be used to form the virtual tripwire; a display in communication with the processor to receive an output from the software module, the output including information used by the display for illustrating the virtual tripwire on the display, the output further enabling the display to illustrate; computed locations of at least a subplurality of the candidate sensors used to form the virtual tripwire through the area of interest; a viewshed of each one of the subplurality of the candidate sensors used to form the virtual tripwire, each said viewshed representing a coverage region of its associated said candidate sensor and selected adjacent ones of the viewsheds of different ones of subplurality of the candidate sensors overlapping with one another; and the display overlaying the viewsheds on the DEM while displaying the virtual tripwire. - View Dependent Claims (16, 17, 18)

19. An apparatus for enabling a user to generate a virtual tripwire through a geographic area of interest using a plurality of sensors to detect the presence of an object or individual that crosses the virtual tripwire, the apparatus comprising:
-
a software module configured to receive; an input for allowing a user to input a digital elevation model (DEM) of the area of interest; an input for enabling a user to define a thickness of the virtual tripwire; a computing subsystem operatively associated with the software module for determining a minimum number of sensors, and a location of each one of said minimum number of sensors on the DEM, required to form the virtual tripwire with the user defined thickness; a display adapted to use information generated by the computing subsystem for illustrating the virtual tripwire as an overlay on the DEM. - View Dependent Claims (20, 21)
