Abstract
A system comprises a plurality of fixed cameras that each having a field of regard. Each point within an area of interest is covered by the field of regard of at least two of the cameras. Each camera captures an image of its field of regard and a plurality of calibration points within the area of interest. A processor calibrates the imaging system by at least associating the coordinates of each of the plurality of calibration points with a calibration pixel corresponding to an image of the calibration point in the image of each of the cameras. The processor geolocates the object of interest within the area of interest by at least comparing the location an image of the object of interest to the calibration pixels in the images generated by each of the plurality of cameras.
