基于色差评定理论的尿液生化分析方法研究

A Study of Biomechanical Method for Urine Test Based on Color Difference Estimation

尿液生化分析是医院临床重要的检查诊断手段。常规尿液分析方法主要有比色目视评价和自动化检测,其中比色目视评价方法已基本被淘汰;自动化检测方法多为医院采用,市场上的尿液生化分析仪价格一般在两万元左右,难以走进普通家庭。计算机视觉不受人的生理和心理因素影响,评价客观、稳定。为此,依据颜色理论,建立计算机视觉系统,对标准阈值颜色和与尿液反应后尿试纸的颜色进行采集、处理、显示和色差评价,便可准确地判定病情级别。我们介绍一种新颖的、方便操作的,可普及于家庭的尿液生化分析方法。实验结果表明,此方法方便、廉价、检测迅速、可实现全程监控,应用前景十分光明。

The biochemical analysis of urine is an important inspection and diagnosis method in hospitals. The convenfional method of urine analysis covers mainly eolorimetrie visual appraisement and automation detection, in which the colorimetrie visual appraisement technique has been superseded basically, and the automation detection method is adopted in hospital; moreover, the price of urine biochemical analyzer on market is around twenty thousand RMB yuan（ ￥ ）, which is hard to enter into ordinary families. It is known that computer vision system is not subject to the physiological and psychological influence of person, its appraisement standard is objective and steady. Therefore, according to the color theory, we have established a computer vision system, which can carry through collection, management, display, and appraisement of color difference between the color of standard threshold value and the color of urine test paper after reaction with urine liquid, and then the level of an illness can be judged accurately. In this paper, we introduce the Urine Test Biochemical Analysis method, which is new and can be popularized in families. Experimental result shows that this test method is easy-to-use and oost-effective. It can realize the monitoring of a whole course and can find extensive applications.
