Abstract
A method of reconstructing a three dimensional image using a structured light pattern system is provided as follows. A class identifier of an observed pixel on a captured image by a camera is extracted. The observed pixel has a coordinate (x, y) on the captured image. A first relative position of the x coordinate of the observed pixel in a tile domain of the captured image is calculated. A second relative position of one of a plurality of dots in a tile domain of a reference image using the extracted class identifier is calculated. A disparity of the observed pixel using the first relative position and the second relative position is calculated.

A method of reconstructing a three dimensional image using a structured light pattern system, the method comprising:
- extracting a class identifier of an observed pixel on a captured image by a camera, wherein the observed pixel has a coordinate (x, y) on the captured image;
- calculating a first relative position of the x coordinate of the observed pixel in a tile domain of the captured image;
