Abstract: A three-dimensional depth measuring method using a structured light camera comprising a first projector, a second projector, and an optical sensor, according to the present disclosure, comprises: a step in which a first light pattern is projected by the first projector; a step in which a second light pattern is projected by the second projector; a step of filtering, by a color filter, a third light pattern in which the first light pattern and the second light pattern reflected from an object overlap, so as to separate the third light pattern into a first filtered pattern and a second filtered pattern; a step of localizing the first filtered pattern and classifying first feature points of the first filtered pattern; a step of localizing the second filtered pattern and classifying second feature points of the second filtered pattern; and a step of obtaining position information of the object on the basis of the first feature points and the second feature points.

Abstract: A synchronization method of a first depth sensing apparatus includes: transmitting a first optical signal to measure a distance to an object; receiving the first optical signal reflected by the object; when recognition of the received first optical signal fails, stopping transmission of the first optical signal and generating first synchronization information for synchronization with at least one second depth sensing apparatus; receiving a third optical signal for synchronization with the first depth sensing apparatus, which is transmitted by the at least one second depth sensing apparatus, and decoding the received third optical signal to extract at least one piece of second synchronization information; determining a time point at which and a cycle in which to re-transmit the first optical signal, based on the first synchronization information and the at least one piece of second synchronization information; and re-transmitting the first optical signal at the determined time point and cycle.

Abstract: An apparatus and method are provided and include an interface unit configured to receive an electrical signal based on light received from a camera; and at least one processor configured to obtain depth information of a 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.
