FUNDUS INFORMATION PROCESSING APPARATUS AND FUNDUS INFORMATION PROCESSING METHOD

摘要

The present inventions relates to a fundus imaging device integrated with a computer processing to comprise a fundus information processing apparatus and method for executing the same in order to produce a panoramic fundus image and to obtain blood vessel information of the fundus. The apparatus and method processes a first fundus image and a second fundus image acquired with a fundus imaging device. The fundus information processing apparatus and method extracts blood vessel shapes from the first and second fundus images, and identifies branching points of the blood vessel of the blood vessel shape through image processing. Further, a plurality of line segments are obtained by interconnecting two predetermined branching points and thereafter identification of two common line segments of the first and second fundus images. The apparatus and method determines relative positional relationship between the branching points constituting at least two of the line segments and thereafter performs comparison operation followed by an alignment operation. By the alignment a panoramic image of the plurality of fundus images is produced along with blood vessel information of the fundus.
