Abstract
An active depth imaging system and method of operating the same captures illuminator-on and illuminator-off image data with each of a first and second imager. The illuminator-on image data includes information representing an imaged scene and light emitted from an illuminator and reflected off of objects within the imaged scene. The illuminator-off image data includes information representing the imaged scene without the light emitted from the illuminator. For each image set captured by the first and second imagers, illuminator-off image data is subtracted from the illuminator-on image data to identify the illuminated light within the scene. The depth of an object at which the light is incident on then is determined by the subtracted image data of the first and second imagers.
