Claim Text:
1. A computer-implemented method comprising: obtaining, by a computer, image data associated with an object; determining, by the computer, based on the image data, a first track associated with the object, wherein the first track is determined by localizing the object in the image data in two-dimensional space relative to a ground plane by identifying a pixel in an image of the image data where the object comes in contact with the ground plane and transforming the pixel coordinates through a ground plane homography to coordinates of a floor plan; obtaining, by the computer, wireless signal data from a device, the device being associated with the object; determining, by the computer, based on the wireless signal data, a second track associated with the device; determining, by the computer, whether trajectories of the first track and the second track are correlated in time and space; and identifying, by the computer, the object based on the correlation of the trajectories of the first track and the second track.
