Claim One:
1. A stereo source image calibration method comprising: receiving an input of a stereo source image, and extracting features respectively from left and right source images; generating feature correspondence information by matching the features, extracted respectively from the left and right source images, with each other; generating a vertical disparity map with respect to the left and right source images, based on a difference between coordinate values from the feature correspondence information; calibrating a difference between the left and right source images by using the generated vertical disparity map; and performing photometric calibration on the left and right source images by: calculating a statistics value of the left and right source images in a location corresponding to the feature correspondence information, performing first color calibration on the left and right source images based on the calculated statistics value, and performing second color calibration by performing histogram matching on left and right source images that are obtained by performing the first color calibration.
