3 Calibration-free Approach to 3D Reconstruction Using A Cube Frame

摘要

PURPOSE: A method for a three-dimensional reconstruction of an object without camera calibration using a cube frame is provided to model the object regardless of camera parameter and position of a light source. CONSTITUTION: A method for restoring a three-dimensional structure of an object includes the steps of taking a photograph of a scene that a line type light emitted from a light plane projector(5) illuminate a target object(4) inside a cube frame(3), recognizing a plurality of LEDs(1) attached to the cube frame(3) in the image and setting up coordinates based on the recognized position, calculating the coordinates of places where a light plane meets the edges of the cube frame(3), and calculating the coordinates of a light stripe formed by making the target object meet with the light plane.
