Intelligent Foreign Body Detection System of Micro-gel Blood Group Test Card

微柱凝胶血型检测卡中的异物严重影响临床检测结果,在分发装盒之前必须经过严格检测,目前主要依赖人工灯检,检测效率低,精准性差。本文设计一种微柱凝胶异物智能检测系统。该系统设计特定波段的红外LED光源获取凝胶卡图像,研究并实现用于提取凝胶卡图像杂质特征信息的改进型高斯滤波算法和二次高斯差分算法,设计识别、跟踪、剔除自动控制装置,实现对有异物的血型检测卡的自动分离。使用纳威尔智能科技有限公司提供的样品进行测试,本文系统检测准确率高于98%,检测异物最小直径为50微米。

The foreign matter in the micro-gel blood group test card seriously affects the clinical test results,so it must be strictly tested before it is distributed and boxed.At present,it mainly depends on manual lamp test,which has low detection efficiency and poor accuracy.In this paper,an intelligent detection system for micro-column gel foreign bodies is designed.In this system,the infrared LED light source with a specific wavelength band is designed to obtain the gel card image,and the improved Gaussian filtering algorithm and quadratic Gaussian difference algorithm for extracting the impurity characteristic information of the gel card image are studied and realized.The automatic control device for identification,tracking and rejection is designed,and the automatic separation of blood type test cards with foreign bodies is realized.Samples provided by Nevil Intelligent Technology Co.,Ltd.are used for testing,the detection accuracy of the proposed system is higher than 98%,and the minimum diameter of foreign bodies detected is 50 microns.
