摘　　要：该文分别从机械、硬件、软件等方面介绍了一种通过CMOS传感器采集图像,然后在Linux系统平台上运用图像处理算法分析免疫胶体金试纸显色反应的判读仪器。判读仪首先为每种测试项目单独设置并保存参数,然后测试项目样品时调用已保存的该项目参数进行测试,因此判读仪可以应用于多种领域多种项目。该文通过对临床中的CRP(C型反应性蛋白)标准样品进行定量实验测试,结果表明仪器拟合优度(R^2=0.99),重复性大于93%。This paper introduces a kind of immune colloidal gold detector instrument from the aspects of machinery, hardware and software. The instrument first collects one image through a CMOS sensor and then analyzes the image with image processing algorithm on Linux platform. Firstly, the instrument sets and stores the parameters separately for each test item, and then calls the saved item parameters when testing the item sample. So, the instrument can be used in a variety of fields and items. In this paper, a quantitative experimental test on C-reactive protein sample was performed, and the results indicate the coefficient of determination what denoted R2 equal to 0.99, and the repeatability is greater than 93%.
