1. A computer-implemented method for tracking an object of interest, comprising:
detecting the object of interest across a set threshold number of frames of a first continuous video stream from a first camera of a valid stereo pair of cameras and a second continuous video stream from a second camera of the valid stereo pair of cameras, wherein the first camera and the second camera are at different physical locations, a portion of a surveillance coverage of the first camera overlaps with a portion of a surveillance coverage of the second camera, a functional range of view of the first camera overlaps with a functional range of view of the second camera, and a principal ray of the first camera and a principal ray of the second camera subtend at an angle that satisfies a threshold angle;
in response to detecting the object of interest across the set threshold number of frames of each continuous video stream, calculating a geolocation of the object of interest by comparing a 2D location of the object of interest in a frame from the first camera of the valid stereo pair of cameras to a 2D location of the object of interest in another frame from the second camera of the valid stereo pair of cameras; and
tracking the geolocation of the object of interest.
