title: 3D reconstruction of gastric surface using endoscopic 3 source photometry.
abstract: Extraction and recognition of three-dimensional (3D) shape information of gastric surface become increasingly important in the field of gastric diagnosis. But there is no practical method that can extract the 3D shape information of gastric surface. For obtaining this 3D information, we developed a new photometric method that can be used in TV endoscope, and evaluated the proposed method theoretically and experimentally. As the results of simulation and experiment, it could be concluded that the proposed method is effective for 3D reconstruction of gastric surface.
