Abstract
An apparatus for calibrating a multiview image may extract feature points from the multiview image and perform image calibration based on the extracted feature points, track corresponding feature points in temporally successive image frames of a first view image, and perform the image calibration based on pairs of corresponding feature points between the feature points tracked from the first view image and feature points of a second view image.
Claims13
A method of calibrating an image, the method comprising:
- extracting feature points from a current frame of an image;
- determining pairs of corresponding feature points between the extracted feature points and initial feature points of a preceding frame of the image;
- generating a fundamental matrix using the pairs of corresponding feature points;
- and
- determining whether a scene change has occurred between the preceding frame of the image and the current frame of the image based on the fundamental matrix and a condition.
