摘　　要：为克服现有血细胞计数仪结构复杂、体积大的缺点,介绍了一种基于个人数字助理(PDA)的便携式血细胞自动计数系统。本系统具有操作简便、体积小、准确度高等优点,能够满足野外血细胞计数检验的需要。系统包括显微镜、CCD摄像头、PDA,并采用eVC++4.0编程,实现了WIN CE操作系统下细胞图片的实时观察与处理,直接获得细胞计数结果。细胞计数综合运用图像处理的多种方法,采用二维最大熵法分割图像,并结合区域增长、空洞填充、区域标号等技术,实现了红细胞、白细胞及血小板的自动计数功能。实验结果表明:与人眼计数结果的相对误差均低于5%。A system based on personal digital assistant（PDA）for automatical counting blood cells is introduced.This system has the advantages of easy operation,small volume,high accuracy,etc,which overcomes the shortages of complex structure and big volume.It satisfies the demand of counting check outdoors.Microscope,CCD camera and PDA compose the system.Using eVC＋＋4.0 the programs are written in WIN CE OS（operating system）for real time observation,processing of the cell image and acquiring the cell numbers directly.The system uses many methods of image processing including two dimensions maximum entropy for image segmentation,region growing,role filling,region labeling,etc and realizes automatical counting of red cells,white cells and blood platelets.The results show that the relative error automatical counting compared with manual counting is lower than 5 %.
