為解決電致變色器件的顏色變化受外界環(huán)境顏色控制的問(wèn)題，設(shè)計(jì)了一種基于單片機(jī)的便攜式顏色自適應(yīng)識(shí)別電路。與傳統(tǒng)顏色識(shí)別電路相比較，該電路利用數(shù)字式的顏色傳感器來(lái)獲取外界環(huán)境顏色，產(chǎn)生的數(shù)字顏色信號(hào)易于單片機(jī)進(jìn)行處理。在電路中，下位機(jī)部分主要負(fù)責(zé)獲取電致變色器件變色參數(shù)及控制電致變色器件的顏色變化;而上位機(jī)部分主要負(fù)責(zé)把下位機(jī)獲取的電致變色器件變色參數(shù)進(jìn)行電壓到顏色的曲線擬合，并通過(guò)藍(lán)牙通信把擬合曲線參數(shù)傳遞給下位機(jī)。結(jié)果表明，該電路能自動(dòng)根據(jù)環(huán)境顏色提供-4~4 V范圍步進(jìn)為0.1 V的電壓來(lái)驅(qū)動(dòng)電致變色器件的顏色顯示，與傳統(tǒng)的顏色識(shí)別電路設(shè)計(jì)相比，識(shí)別的精度和速度都得到了明顯改善。 Abstract: In this paper， a portable adaptive circuit for color identification(PACCI) based on MCU was designed. Compared to the traditional color identification circuit， the PACCI adopts digital sensor to detect the color data from external environment and further generate digital color data， which can be processed easily by MCU. In PACCI， the slave is mainly responsible for detecting the color parameters of the corresponding elcreochromic device and further driving it. For the master， which is mainly responsible for the color curve fitting based on the parameters of the electrochromic device， and transmits the fitting parameters to the slave through the bluetooth device. The results show that the PACCI can provide the basis voltage range from -4V to 4V automatically based on the colors of external environment with step as 0.1V to drive the corresponding electrochromic device. Compared to the traditional color RecognItion circuit， the RecognItion accuracy and speed of PACCI have been improved significantly.

TCA2003是徠卡測(cè)量系統(tǒng)于1998年推出市場(chǎng)的世界上第一臺(tái)帶有目標(biāo)自動(dòng)照準(zhǔn)功能(Automatic Target RecognItion)的全自動(dòng)全站儀，又被稱作“測(cè)量機(jī)器人”，其代表世界大地測(cè)量?jī)x器領(lǐng)先水平的0.5"測(cè)角精度和1mm+1×10－6Dm測(cè)距精度使其成為世界各國(guó)高精度大地測(cè)量應(yīng)用中的一款經(jīng)典儀器。 從1999年進(jìn)入中國(guó)市場(chǎng)開始，TCA2003先后在大型水電站和水利樞紐大壩監(jiān)測(cè)、地鐵隧道和基坑、核電站和大型鍋爐等工業(yè)現(xiàn)場(chǎng)高精度測(cè)量及自動(dòng)化監(jiān)測(cè)項(xiàng)目中投入使用，并收到良好的工程應(yīng)用效果，尤其是其對(duì)各種惡劣環(huán)境的抵御能力和測(cè)量性能穩(wěn)定性，更是得到眾多用戶的贊許。記得從頭至尾負(fù)責(zé)廣州地鐵黃沙站自動(dòng)化監(jiān)測(cè)項(xiàng)目實(shí)施的廣州亞奧公司的張總曾如此激動(dòng)的評(píng)價(jià)TCA2003的穩(wěn)定性和耐用性，“我們?cè)趶V州地鐵黃沙站使用的6臺(tái)TCA2003使用4年多時(shí)間性能一直都很穩(wěn)定，精度保證在指標(biāo)中”。此后TCA2003在浦東磁懸浮、盧浦大橋、青藏鐵路、武廣高速鐵路、國(guó)家大劇院、“鳥巢”、廣州電視臺(tái)發(fā)射塔等一批國(guó)家重大工程和特殊建筑物建設(shè)項(xiàng)目的高精度工程測(cè)量都有所應(yīng)用。目前已經(jīng)形成在礦山監(jiān)測(cè)、地質(zhì)災(zāi)害和工程搶險(xiǎn)監(jiān)測(cè)等新興自動(dòng)化測(cè)量應(yīng)用領(lǐng)域、原有各種高精度自動(dòng)化測(cè)量和工程測(cè)量應(yīng)用領(lǐng)域百花競(jìng)放的態(tài)勢(shì)。 十年的市場(chǎng)檢驗(yàn)，我們足以對(duì)一個(gè)測(cè)量?jī)x器的品質(zhì)和性能作出可靠的評(píng)價(jià)。出版此文集一方面是總結(jié)用戶的應(yīng)用經(jīng)驗(yàn)，另一方面也希望能給徠卡TCA2003用戶提供參考借鑒。

Hidden_Markov_model_for_automatic_speech_RecognItion This code implements in C++ a basic left-right hidden Markov model and corresponding Baum-Welch (ML) training algorithm. It is meant as an example of the HMM algorithms described by L.Rabiner (1) and others. Serious students are directed to the sources listed below for a theoretical description of the algorithm. KF Lee (2) offers an especially good tutorial of how to build a speech RecognItion system using hidden Markov models.
