摘　　要：研制了一种基于CMOS传感器的胶体金免疫层析试纸条的尿素酶定量检测系统。该系统由硬件和软件两部分组成,硬件部分利用CMOS传感器和条码扫描仪来获取检测图像和病人的个人信息。软件部分除了实现免疫层析试纸条光信号的分析和诊断还实现病人信息采集和建立病人信息数据库等关键功能。该软件采用了k-means聚类算法,实现采集图像的精准分析。通过检测200例尿素酶样品试纸条,验证了设备的稳定性和准确性。该系统体积小、便携性强且具有优秀的续航能力,可用于长时间的临床、野外和社区体检。A new immunochromatographic test reader based on CMOS sensor is presented,which is used for detecting colloidal gold strip quantitatively. This system is made of hardware system and software system. The function of the hardware system is to get the detecting image and personal information with the CMOS sensor and the barcode scanner. In addition to realizing the analysis and diagnosing of optical signal of the test strip,the software system can also collect the patient＇s information and build the database to manage patients＇ information.A clustering algorithm called k-means is used to process the image,realizing the accurate analysis of the image.200 urea enzymes samples are collected to test the accuracy and the stability of this reader. This reader has a small volume and a good portability and can run for long durations,it possesses advantages for clinical detection,outdoor detection and community examination.
