IDENTIFYING AN OBJECT IN A VOLUME BASED ON CHARACTERISTICS OF LIGHT REFLECTED BY THE OBJECT

摘要

An object is identified or tracked within a volume by projecting a light beam encoded with one or more predefined properties to have a predefined optical structure into the volume. A detector captures light from the predefined optical structure reflected from the volume. By analyzing one or more characteristics of light from the predefined optical structure reflected from the object, the object is segmented from the volume.
