Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 14:
15. A system for analyzing an object in a scene, comprising:
a light source attached to a first element of a plurality of elements comprised in the object;
a camera device configured to capture a sequence of images of the scene; and
a tracking controller configured to:
detect, based on a pattern of local light change across the sequence of images, the light source in the scene;
determine a location of the light source in at least one image of the sequence of images;
generate, based on the location of the light source and a dynamic model of the object, a region-of-interest for analyzing the object; and
generate an analysis result of the object based on the region-of-interest, wherein a pre-determined task is performed based on the analysis result,

wherein the dynamic model describes mechanical linkages among the plurality of elements,
wherein the location of the light source in the at least one image corresponds to the location of the first element in the scene, and
wherein generating the region-of-interest comprises:
determining, based on the mechanical linkages, a range limitation of a second element of the plurality of elements relative to the first element, and
determining, based on the location of the light source and the range limitation, a probability map of the location of the second element in the scene.
