Abstract
A method of decoding hierarchically orthogonal structured light and a 3-D depth measurement system using the same include a step of detecting boundary lines encoded at an identical position between layers and a boundary line inheritance step of converting the detected boundary lines into identical boundary lines. The present invention relates to a method of precisely searching for the boundary line of a pattern of radiated structured light based on the real coordinate system of an image plane, and an object thereof is to search for a boundary line irrespective of the reflection of a surface of an object, clearly classify a true boundary line and a false boundary line in a poor radiance environment, and increase the accuracy of a boundary line placed in another layer through inheritance.
