摘要
A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.
