Abstract:
Calibration methods for calibrating image capture devices of an around view monitoring (AVM) system mounted on vehicle are provided, the calibration method including: extracting local patterns from images captured by each image capture device, wherein each local pattern is respectively disposed at a position within the image capturing range of one of the image capture devices; acquiring an overhead-view (OHV) image from OHV point above vehicle, wherein the OHV image includes first patterns relative to the local patterns for the image capture devices; generating global patterns from the OHV image using the first patterns, each global pattern corresponding to one of the local patterns; matching the local patterns with the corresponding global patterns to determine camera parameters and transformation information corresponding thereto for each image capture device; and calibrating each image capture device using determined camera parameters and transformation information corresponding thereto so as to generate AVM image.

Claim (Index 14):
The AVM system as claimed in  claim 13 , wherein the AVM device further extracts the first patterns from the OHV image, performs coordinate conversion to determine a transformation from a first coordinate relative to the OHV image plane to a second coordinate parallel to ground plane, and applies the determined transformation to the first patterns to generate the global patterns.
