基于峰值搜索和模板匹配的心电监护仪数值提取方法
An extraction method for ECG monitor based on peak search and template matching
摘要
Abstract
In order to improve the work efficiency of electrocardiograph(ECG)monitor and save procurement cost,we proposed a digital method based on ECG monitor.Firstly,an optical camera was installed on the ECG monitor to obtain the video image of the ECG monitor in real time.Then,the peak search method was used to realize image segmentation and region of interest recognition.Finally,the template matching method was used to recognize characters,the typical values on the ECG monitor were extracted regularly,and the data were stored and processed.The experimental results showed that this method was less affected by light and shooting angle,and had strong adaptability to the environment,which could meet the needs of data extraction.This research can realize the digital improve-ment of ECG monitor.关键词
