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 image processing technology, dealt with the correction of barrel distortion by lens adjustment, calculated the gastric ulcer 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 patients and the results were compared with the traditional formula method. It could be well concluded that this technology is safe, accurate and economical for measuring gastric ulcer area.
在科研和临床实践中，测量病变区域非常重要。本研究旨在利用计算机可视化技术解决桶形畸变问题并测量病变区域。为了最终获得精确的病变区域，该研究基于原始的内窥镜系统和数字图像处理技术，通过镜头调整处理桶形畸变的校正，借助Qt数据库计算胃溃疡面积，最终开发了一款图像处理软件——内窥镜助手（EAS）。结果表明，EAS在体外是准确的。用它测量了45例患者的胃溃疡面积，并将结果与传统公式法进行了比较。可以很好地得出结论，这项技术用于测量胃溃疡面积是安全、准确且经济的。
