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: An optical device is disclosed. An optical device of the present invention that generates a depth map for an object comprises: a projector for irradiating electromagnetic waves onto an object; an optical receiver for receiving reflected waves reflected from the object; and a processor for generating a first depth map for the object on the basis of the direction of arrival of the received reflected waves, generating a second depth map for the object on the basis of the arrival time of the received reflected waves, and combining the first depth map and the second depth map and generating a depth map for the object.

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.

Abstract: A method and device are provided for obtaining a 3D image. The method includes sequentially projecting a plurality of beams to an object, each of the plurality of projected beams corresponding to a respective one of a plurality of sectors included in a pattern; detecting a plurality of beams reflected off of the object corresponding to the plurality of projected beams; identifying time-of-flight (ToF) of each of the plurality of projected beams based on the plurality of detected beams; identifying a distortion of the pattern, which is caused by the object, based on the plurality of detected beams; and generating a depth map for the object based on the distortion of the pattern and the ToF of each of the plurality of projected beams, wherein the plurality of detected beams are commonly used to identify the ToF and the distortion of the pattern.
