【摘要】：牛乳体细胞的数量是诊断奶牛是否患有乳房炎的国际性指标,同时影响着牛奶的产量和品质,因此,对牛乳体细胞数量的检测具有重要的现实意义。在信息移动化的时代,便携的智能设备逐步取代传统设备,基于移动终端的牛乳体细胞检测系统是传统牛乳体细胞检测仪的一个重要发展方向。相对于传统检测仪,该系统具有体积小、集成化高、便携、智能等优点,在实时检测方面具有广阔的应用前景。基于Android平台的牛乳体细胞计数系统由计数装置和计数软件两部分组成。本论文主要研究内容包括:①从牛乳体细胞检测意义入手,介绍了国内外现有的牛乳体细胞检测技术和检测仪器,结合便携式移动平台的发展状况,提出牛乳体细胞检测技术与移动平台相结合的新方向和思路,指出本论文所构建的牛乳体细胞计数系统的实时性和便携性。②在MATLAB环境下仿真处理牛乳体细胞荧光图像,尝试了多种图像预处理经典算法,并进行对比和选择,对预处理后的图像采用基于形态学顶帽变换的阈值分割算法二值化,再采用火蔓式计数算法计数,为基于Android平台的牛乳体细胞计数软件提供了图像处理算法支持。③分析了Android结构框架及Android应用程序的开发,阐明在移动设备中实现牛乳体细胞计数的可行性,为该软件的开发提供了架构平台。基于eclipse开发软件,使用Java编程语言,设计和编写了在Android操作系统下的牛乳体细胞计数软件,包括界面显示、图像获取和图像处理模块,实现了对牛乳体细胞的图像获得、截取、预处理、阈值分割和细胞计数等功能,该软件具有界面清晰、简明和响应快速的特征。④设计了牛乳体细胞计数装置结构,重点研究了其中的微流控采样和荧光放大模块。对基于Android平台的牛乳体细胞计数系统进行了综合测试和对比实验,验证了该系统能够现场、实时、准确的对新鲜牛奶中体细胞计数。本论文在最后总结了该系统的主要研究内容并指出系统中的不足和缺陷,为进一步工作提出了修改意见。
[Abstract]:The number of milk somatic cells is an international index to diagnose mastitis in dairy cows, and it also affects the yield and quality of milk. Therefore, the detection of milk somatic cells is of great practical significance. In the era of information mobility, portable intelligent devices are gradually replacing the traditional equipment. The detection system of bovine milk somatic cells based on mobile terminal is an important development direction of traditional milk somatic cell detector. Compared with the traditional detector, the system has the advantages of small volume, high integration, portability, intelligence and so on, so it has a broad application prospect in real-time detection. The counting system of bovine milk somatic cells based on Android platform consists of two parts: counting device and counting software. The main research contents of this thesis are as follows: starting with the significance of bovine milk somatic cell detection, this paper introduces the existing domestic and foreign bovine milk somatic cell detection techniques and instruments, combined with the development of portable mobile platform. A new direction and idea of combining the technology of milk somatic cell detection with mobile platform is proposed. The real-time and portability of the milk somatic cell counting system constructed in this paper is pointed out. 2. The real-time and portability of the system is simulated to process the bovine milk somatic cell fluorescence image under the MATLAB environment. Several classical image preprocessing algorithms are tried and compared and selected. After preprocessing, the threshold segmentation algorithm based on morphological top hat transform is binarized, and then the counting algorithm is adopted. This paper provides image processing algorithm support for milk somatic cell counting software based on Android platform, analyzes the Android structure framework and the development of Android application program, and illustrates the feasibility of realizing bovine milk somatic cell counting in mobile devices. It provides an architecture platform for the development of the software. Based on eclipse development software and Java programming language, the software of bovine milk somatic cell counting under Android operating system is designed and written, including interface display, image acquisition and image processing module, which realizes the image acquisition and interception of bovine milk somatic cells. Pretreatment, threshold segmentation and cell counting. The software has the features of clear interface, concise and quick response, designed the structure of bovine milk somatic cell counting device, and focused on the study of microfluidic sampling and fluorescence amplification module. The system of milk somatic cell counting based on Android platform was tested and compared, and it was proved that the system could count the somatic cells in fresh milk in real time. At the end of this paper, the main research contents of the system are summarized, and the shortcomings and defects of the system are pointed out.
