【摘要】：目前,国家标准规定的和国际上通用的油脂颜色检测装置是罗维朋比色计或者赛波特比色仪,但是这两款比色计都采用目测的方法,存在较大的主观误差,因此采取较为客观的技术手段测定油品颜色的方法成为必要。人是通过眼、脑和生活经验产生一种对光的视觉效应识别颜色的,计算机则是将颜色数字化、符号化,通过研究与计算颜色数字化的分布判定颜色的分类。本文使用摄像头取代赛波特比色仪原有的观察镜,将采集到的图像传输到上位机进行处理,同时根据油品颜色的特殊性,在研究过程中使用颜色直方图作为图像的颜色特征。使用SVM支持向量机处理图像结合硬件闭环反馈机制智能化的测定油品颜色。论文的主要工作如下:(1)阅读了大量国内外参考文献,介绍了颜色识别和SVM支持向量机的研究现状、应用领域,提出了基于图像处理的赛波特比色仪的设计;在图像处理方面,Opencv与SVM支持向量机相结合实现智能比色;(2)利用SVM支持向量机多类分类器通过图像处理的方式实现赛波特比色仪比色过程;同时通过与相关硬件构成的闭环反馈控制输入输出的关系,在颜色分类控制方面有了较大的改善。本文依据SVM支持向量机的分类原理、赛波特比色仪操作过程、以及图像处理的原理设计了基于图像处理的赛波特比色仪,改造完成的仪器能够实现自动吸油、排油、以及测定油品颜色,达到预期的效果,具有一定的应用价值。
[Abstract]:At present, the national standard and the international common oil color detection device is Rovibon colorimeter or Cyberport colorimeter, but these two colorimeter both use visual method, there is a large subjective error. Therefore, it is necessary to adopt more objective technical means to determine the color of oil products. People recognize the color through the eye, brain and life experience, while the computer digitizes the color. In this paper, the camera is used to replace the original observation mirror of the Seabot colorimeter, and the collected image is transmitted to the upper computer for processing. At the same time, according to the particularity of oil color. The color histogram is used as the color feature of the image in the research process. The color of oil product is intelligently measured by using SVM support vector machine (SVM) image processing and hardware closed-loop feedback mechanism. The main work of this paper is as follows: (. 1) read a large number of references at home and abroad. This paper introduces the research status of color recognition and SVM support vector machine, and puts forward the design of Seabot colorimeter based on image processing. In the aspect of image processing, the combination of Opencv and SVM support vector machine can realize intelligent colorimetric. 2) using SVM support vector machine multi-class classifier to realize the colorimetric process of Seabot colorimeter by image processing; At the same time, the color classification control is improved by the relationship between the closed-loop feedback control and the related hardware. This paper is based on the classification principle of SVM support vector machine. The operation process of Seabot colorimeter and the principle of image processing are designed. The modified instrument can automatically absorb oil, drain oil and determine the color of oil. To achieve the desired results, has a certain application value.
