摘要
无创性食管曲张静脉测压是当前的一个研究热点,本文提出了一种基于计算机视觉的食管曲张静脉测压系统,该系统采用基于PCI总线的图像采集、USB接口的压强采集、边缘检测、动态跟踪等处理方法。
A non-invasive manometry of esophageal varices is a hot study point. This paper develops a method based on computer vision. Experiments results reveal that correct pressure value can be got quickly. This system applied the methods of image-acquisition based on PCI bus, pressure data-acquisiton based on USB interface, edge detection, dynamic tracking and so on.
