【摘要】：比色分析法是一種有效的定量檢測方法,在眾多領域中有著重要的應用。隨著技術的發(fā)展,數(shù)字圖片比色法被廣泛的研究和應用,該方法通過分析數(shù)字圖片的相關顏色信息來實現(xiàn)對物質(zhì)的定量檢測。傳統(tǒng)的數(shù)字圖片分析方法一般通過分析圖片顏色的RGB值、CMYK值等建立與待測物質(zhì)的關系,但是當所分析的物質(zhì)顏色色調(diào)發(fā)生變化時,這些參數(shù)已不再適用。而現(xiàn)有的基于顏色其它指標分析色調(diào)變化的體系時,存在計算復雜和工作曲線非線性等問題。隨著電子技術的飛速發(fā)展,智能手機的普及程度和性能都有了很大的提升。由于智能手機具有良好的圖像采集功能和操作系統(tǒng)中開放的開發(fā)環(huán)境,因此可以自主開發(fā)應用程序來對所采集到的數(shù)字圖片進行處理分析并實現(xiàn)面向現(xiàn)場的快速檢測。本文提出利用智能手機和應用程序(APP)分析顯色產(chǎn)物數(shù)字圖像的主波長的方法實現(xiàn)對顏色色調(diào)發(fā)生變化的體系中相關量的定量檢測。本文主要研究內(nèi)容如下:1.研究了一種利用主色波長定量描述顏色的方法,通過將顏色初始的RGB信息轉(zhuǎn)換到CIE XYZ色度系統(tǒng)實現(xiàn)顏色的定量描述。并研究各類顏色設備在顏色復現(xiàn)過程中的工作機理,在設備中顏色空間的轉(zhuǎn)換。2.研究了Android智能手機的操作系統(tǒng)及應用程序開發(fā)環(huán)境的搭建過程和應用程序的開發(fā)流程。將顏色主波長的圖像分析過程開發(fā)成智能手機應用程序并驗證其可行性與準確性。3.將所開發(fā)應用程序應用于溶液pH值檢測。將所測的結(jié)果與pH計測得的結(jié)果進行對比,證明該檢測系統(tǒng)的準確性與可行性并說明該系統(tǒng)對于檢測顏色色調(diào)發(fā)生變化的顯色體系的適用性。
[Abstract]:Colorimetric analysis is an effective quantitative detection method and has important applications in many fields. With the development of technology, digital image colorimetry has been widely studied and applied. The traditional digital image analysis method usually establishes the relationship between the RGB value and CMYK value of the image color, but these parameters are no longer applicable when the color hue of the material is changed. However, the existing systems based on other color indexes have some problems such as complexity of calculation and nonlinearity of work curve. With the rapid development of electronic technology, the popularity and performance of smart phones have been greatly improved. Because smart phone has good image collection function and open development environment in the operating system, it can develop application program independently to process and analyze the collected digital image and realize the fast detection oriented to the field. In this paper, a method of analyzing the main wavelength of digital image of color product by using smart phone and application program (app) is proposed to realize the quantitative detection of the correlation quantity in the system where the color hue changes. The main contents of this paper are as follows: 1. In this paper, a method of quantitative color description using main color wavelength is studied. The color quantitative description is realized by converting the original RGB information of color to CIE XYZ chromaticity system. The working mechanism of all kinds of color equipments in the process of color reproduction is studied, and the conversion of color space in the equipment. 2. 2. The operating system and application development environment of Android smart phone are studied. The image analysis process of color master wavelength is developed into a smartphone application and its feasibility and accuracy. 3. 3. The developed application program was applied to the pH detection of solution. By comparing the measured results with those obtained by pH measurement, the accuracy and feasibility of the system are proved, and the applicability of the system to detecting the color system with color tonal changes is illustrated.
