- The Area Measurement Method for Esophageal Lesion under Endoscopy
抄録
The risk of developing esophageal cancer from Barrett’s Esophagus (BE) is associated with its size. However, the study to measure BE area is not advanced well. In this paper, we propose the method to measure BE area from one endoscopic image with camera distance. First, we assume that the esophagus is a cylinder and the camera is a pinhole camera because 3D reconstruction of no-feature points object like an esophagus is difficult. And then, we get BE area indirectly by calculating the surface area of this virtual cylinder. In measurement experiments, we used USB camera and cylinder phantoms to evaluate the accuracy of the proposed method. The errors were about 4-6% in the bottom area, about 10% in the side area, and about 1±2.5 mm in the phantom’s height measurement.
