Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for virtual inductance loop technology. In one aspect, a method includes calibrating, using calibration parameters, cameras directed towards a scene, obtaining, by the cameras, images corresponding to the scene, identifying reference structures in the scene, and determining, based on the reference structures and the images, locations in the scene for generating virtual inductance loop lines in the scene. The method also includes generating the virtual inductance loop lines to be imposed on the images, comparing the virtual inductance loop lines to determine one or more offsets, and determining, based on the offsets, characteristics of the scene.
