Description
<p>Because the view angle of the endoscope is narrow, it is difficult to get the whole image of the digestive tract at once. If there are more than two lesions in the digestive tract, it is hard to understand the 3D positional relationship among the lesions. Because the virtual endoscopy is designed to detect the irregularity of the surface, it cannot detect lesions that lack irregularity including early cancer. In this study, we propose a method for generating unfolded view of the digestive tract using stereo endoscope images. By fitting the cylinder to the reconstructed three-dimensional shape of the digestive tract from obtained stereoscopic images, unfolded views of the digestive tract was generated. Moreover, we estimated the position change of the endoscope from sequential endoscopic images and stitched each unfolded views for expanding the area of the generated images and improving accuracy.</p>
