    Abstract: An apparatus and method for measuring a depth in a structured depth camera system including a projector and a camera for receiving light radiated by a source pattern from the projector and reflected from one or more objects in a scene is provided. The apparatus includes an interface unit configured to receive an electrical signal based on light received from the camera; and at least one processor configured to obtain depth information of the scene based on the electrical signal received from the interface unit, wherein the at least one processor is configured to identify a recognition pattern corresponding to the light received by the camera based on the electrical signal, to obtain a total distance value between properties of a partial source pattern corresponding to a target fragment in the source pattern and properties of a partial recognition pattern corresponding to the target fragment in the recognition pattern, and to estimate depth information of the target fragment based on the obtained total distance value.
