Abstract
A depth camera assembly (DCA) configured to determine distances between the headset and one or more objects in an area surrounding the headset. The DCA includes an imaging device, an illumination source, and a controller. The controller identifies objects in a portion of the local area, determines a depth zone for each object and corresponding structured light (SL) illumination parameters including a SL pattern for each object based on the depth zone, instructs the illumination source to illuminate a scene comprising the one or more objects with the determined SL pattern, and instructs the imaging device to capture images of the illuminated objects. The controller determines the depth information for the illuminated objects and updates the depth information associated with the objects.
