摘　　要：内镜下病灶大小的测量在科学研究和临床实践中有重要意义,如何解决内镜下病灶的桶形畸变,并且进行病灶面积计算机视觉测量数字化是本研究重点。本研究基于原有胃镜系统,以获取病灶准确物理面积为最终目的,运用数字图像处理技术,校正胃镜镜头桶形畸变,计算其面积,借助于Qt库,开发出胃镜图像处理软件Endoscope Assistant(EAS)。体外试验显示其良好的准确性,并应用该软件对45例患者的胃溃疡面积进行测量,并与传统测量方法比较,证明该技术可以安全简便并准确地测量病灶面积。It is of great importance to measure the lesion area in scientific research and clinical practice. The present study aims to solve barrel distortion and measure lesion area with the technology of computer visualization. With the ultimate purpose to obtain the precise lesion area, the study, based on the original endoscopy system and digital im- age processing technology, dealt with the correction of barrel distortion by lens adjustment, calculated the gastric ul- cer area with the aid of Qt database and finally developed an image processing software--Endoscope Assistant（EAS）. The results showed that the EAS was accurate in vitro. It was employed to measure the gastric ulcer area of 45 pa- tients and the results were compared with the traditional formula method. It could be well concluded that this tech- nology is safe, accurate and economical for measuring gastric ulcer area.
