Many previous studies have been able to reconstruct the complete stomach shape using the structure-from-motion approach; however, such methods require real or virtual indigo carmine (IC) dyeing to enhance endoscopic images before the 3D reconstruction takes place. In this study, we propose an alternative approach by enhancing the appearance of gastric tissue texture and reducing the effect of noise. We show that it is possible to perform 3D reconstruction using monocular endoscopy and without the need for chromoendoscopy. In addition, we show that our method can increase the number of feature matches and maintain the feature consistency, which is critical to the performance of stomach 3D reconstruction. |
