METHOD AND SYSTEM WITH MULTIPLE CALIBRATION SCHEME

摘要

Provided are a camera calibration method using a multiple calibration technique and an image system using the same. The camera calibration method according to an embodiment of the present invention includes a step of extracting factors of cameras by photographing a pattern image; a step of converting the factors by arranging the pattern images; and a step of extracting the factors of the cameras of which the factors are converted again by photographing the pattern image again. Therefore, the factors of the cameras can be determined depending on installation and arrangement properties so that the present invention can generate a multi-view video and improve the quality of image processing such as depth image warping. Ultimately, the present invention can perform clean three-dimensional effects and converts viewpoints when the multi-view video is played.
