SAMPLING METHOD OF REFERENCE POINT FROM MARKER FOR IMAGE MERGING AND SYNCHRONIZATION OF COORDINATION

摘要

PURPOSE: A reference point extracting method for coordinate synchronization is provided to accurately extract a reference point which indicates a marker for coordinate synchronization. CONSTITUTION: An image including a marker for image matching or coordinate synchronization is obtained(S100). A plurality of reference points is appointed in the image within the obtained image(S110). A reference point is extracted from a standard point. The image matching or coordinate synchronization are performed by using the extracted reference point(S120).
