基于神經(jīng)網(wǎng)絡(luò)的測色儀器系統(tǒng)誤差分析和校正

為了提高工業(yè)生產(chǎn)過程中廠泛應(yīng)用的光電積分測色儀的測試精度，分析、研究儀器誤差成為儀器設(shè)計(jì)的重要內(nèi)容之一。在
分析探測器的光譜三刺激非線性誤差的基礎(chǔ)上，進(jìn)行了測色儀原理誤差的研究，提出了基于人工神經(jīng)網(wǎng)絡(luò)的非線性濾波器的方法，并
建立了一個(gè)基于神經(jīng)網(wǎng)絡(luò)的非線性濾波器黑箱模型。實(shí)驗(yàn)表明:用此三刺激值計(jì)算的色品坐標(biāo)、色差等參數(shù)均達(dá)到了設(shè)計(jì)要求。

Abstract; In order to increase the measurement accuracy of widely used photoelectric integral colorimeten,anaiyzing and studying the error of the instrument has become one of the important tasks for designing the instrument. On the basis of analysis of spectral tristimulus non-linear error of the detector,the research on principle eror of colorimeters is achievcd and the method of non-linear filter bused on artificial neural network
is proposed, and a non-linear filter black box based on neural network is established. The experiment shows that the parameters calculated tristimulus,e.g. c hromaticityc umdinates,colord ifferenee,ete.，meetth e,m quhrmentso fd esign
