<P>PROBLEM TO BE SOLVED: To generate volume data from an endoscopic image captured by an endoscope inserted in an anatomical structure. <P>SOLUTION: A plurality of endoscopic images and a plurality of virtual endoscopic images are obtained. Then, an endoscopic image captured at a predetermined position of the anatomical structure is extracted from the plurality of endoscopic images obtained, and a comparative virtual endoscopic image virtually generated as if it is captured at a position corresponding to the predetermined position is extracted from the plurality of virtual endoscopic images obtained, and the extracted images are associated with each other. A three-dimensional position corresponding to each of a plurality of pixels forming the endoscopic image captured at the predetermined position is calculated based on a three-dimensional position of each of a plurality of pixels forming the comparative virtual endoscopic image. Then, volume data is generated from the endoscopic image captured at the predetermined position based on a pixel value of each of the plurality of pixels forming the endoscopic image captured and the three-dimensional position calculated for each pixel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
