Abstract

An apparatus for correcting a stereoscopic image using matching information, includes: a matching information visualizer receiving input of original stereoscopic images and intuitive matching information and visualizing a pair of stereoscopic images based on the intuitive matching information; a correction information processor obtaining a statistical camera parameter based on the intuitive matching information and correcting the received stereoscopic image using the statistical camera parameter; and an error allowable controller providing allowable error information to the correction information processor in consideration of an error allowable degree according to a selected time from the received intuitive matching information and preset human factor guide information, to extract a correlation between stereoscopic images using a stereoscopic image and provided information, thereby helping such that an erroneously photographed image is correctly photographed or correcting the image such that the erroneously photographed image is correctly interpreted, which leads to minimization of visual fatigue.

Claims

1. An apparatus for correcting a stereoscopic image using matching information, comprising:

a matching information visualizer receiving input of original stereoscopic images and intuitive matching information and visualizing a pair of stereoscopic images based on the intuitive matching information;

an object information processor processing the intuitive matching information by processing matching point information for matching points that simultaneously exist in the pair of stereoscopic images of the original stereoscopic images;

a correction information processor obtaining a statistical camera parameter based on the intuitive matching information and correcting the received stereoscopic image using the statistical camera parameter in consideration of a visual fatigue degree according to an error and a time length of the received matching information using preset human factor guide information; and

an error allowable controller providing allowable error information to the correction information processor in consideration of an allowable degree of error of a pixel or a relative value according to a time associated with the received intuitive matching information and the preset human factor guide information, wherein the intuitive matching information is information corresponding to geometric attributes of an object in an image that is input by a user.

2. The apparatus of claim 1, wherein the matching information visualizer includes:

a matching point information processing unit providing matching points in the pair of stereoscopic images and on the original stereoscopic image;

a matching region information processor assisting input and output of intuitive matching region information using three-dimensional model information with respect to a standard object stored in the object information processor.

3. A computer implemented method for correcting a stereoscopic image using matching information and performed by a processor of the computer, the method comprising:

receiving input of original stereoscopic images;

receiving input of intuitive matching information;

processing the intuitive matching information for visualizing a pair of the stereoscopic images based on the intuitive matching information; and
