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.

Three-dimensional depth measuring device and method

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.
