| Abstract: | A computer vision based navigation technology for an endoscope is studied. First, the principle of endoscope navigation is introduced. Then, a new fast method of auto-threshold is presented to be used for finding path in endoscope navigation. The auto-thresholding algorithm is described for extracting the lumen from endoscope images. This auto-threshold method is based on Ostu's method and the method is optimized by analyzing the endoscope image. Then the swing angle of endoscope head is computed by 3D method mapping. At last, an intelligent navigation system of endoscope is designed using the new auto-threshold algorithm. Experiments show that this algorithm has good veracity and stability. |
