Abstract
A method for object tracking. The method includes capturing a sequence of images of a scene, detecting, by a hardware processor, based on a pattern of local light change across the sequence of images, a reflective light source in the scene, comparing, by the hardware processor in response to detecting the reflective light source, a location of the reflective light source in at least one image of the sequence of images and a target position within the at least one image to generate a result, and generating, by the hardware processor based on the result, a control signal for changing a field-of-view of a camera device such that the reflective light source substantially aligns with the target position within the field-of-view, wherein the reflective light source emits an object-reflected light.
