Abstract
A method and system for determining the location of objects using a plurality of full motion video cameras where the location is based on the intersecting portions of a plurality of three-dimensional shapes that are generated from the video data provided by the cameras. The three-dimensional shapes include two-dimensional shapes that contain predetermined traits in each of the frames of the video signals.

1-20. (canceled)
A method of determining the location of objects, the method comprising:
- receiving information from a plurality of sensors monitoring an area;
- identifying, in data captured by respective first sensors of the plurality of sensors, one or more predetermined traits of a detected object;
- demarcating a portion of the captured data that contains the identified one or more predetermined traits with a two-dimensional shape;
- defining a three-dimensional shape for each first sensor that maintains the detected object in a field of view, the three-dimensional shape extending from at least the two-dimensional shape to the respective first sensor in each data frame;
- calculating an intersecting shape where two or more of the defined three-dimensional shapes of the first sensors intersect;
- and
- calculating a center point of the intersecting shape that is identified as the location of the object.

- a plurality of sensors for monitoring an area;
- and
- a computing device for locating an object, the computing device being configured to:
- receive information from first sensors of the plurality of sensors;
- identify, in data captured by respective first sensors of the plurality of sensors, one or more predetermined traits of a detected object;
- demarcate a portion of the captured data that contains the identified one or more predetermined traits with a two-dimensional shape;
- define a three-dimensional shape for each first sensor that maintains the detected object in a field of view, the three-dimensional shape extending from at least the two-dimensional shape to the respective first sensor in each data frame;
- calculate an intersecting shape where two or more of the defined three-dimensional shapes of the first sensors intersect;
