簡(jiǎn)介：隨著經(jīng)濟(jì)的快速發(fā)展，我國(guó)正在大規(guī)模建設(shè)高速鐵路客運(yùn)專線。由于高速鐵路列車運(yùn)行速度快，對(duì)線路平順性要求高，大大提高了對(duì)測(cè)量精度的要求。為保證測(cè)量精度的要求對(duì)高速鐵路線下任意點(diǎn)的核檢是非常必要的。傳統(tǒng)的核檢方式通常是在室內(nèi)根據(jù)設(shè)計(jì)圖紙?zhí)崆坝?jì)算需核檢項(xiàng)目的理論值，然后在現(xiàn)場(chǎng)對(duì)實(shí)物進(jìn)行測(cè)量，并計(jì)算出差值，看誤差是否在規(guī)范允許范圍內(nèi)。這種核檢方式需要測(cè)量完后計(jì)算，以致不能實(shí)時(shí)出現(xiàn)結(jié)果。盡管隨著技術(shù)的發(fā)展，軌道核檢開(kāi)始采用“軌道測(cè)量?jī)x”和測(cè)量?jī)x器相結(jié)合的方式實(shí)現(xiàn)數(shù)據(jù)隨機(jī)、動(dòng)態(tài)采集和傳輸，可以實(shí)時(shí)檢測(cè)線上軌道任何部分幾何狀態(tài)，而對(duì)線下結(jié)構(gòu)部分，如路基、橋梁、隧道幾何位置的核檢，由于空間位置的特殊性，儀器難以實(shí)現(xiàn)。另外，儀器輸出的結(jié)果大部分是以文本字符方式輸出，缺乏直觀的可視化圖形界面。論文在以開(kāi)發(fā)高鐵線下任意點(diǎn)三維動(dòng)態(tài)可視化實(shí)時(shí)核檢系統(tǒng)為課題背景下，完成了系統(tǒng)開(kāi)發(fā)的前提和基礎(chǔ)部分，即設(shè)計(jì)數(shù)據(jù)導(dǎo)入時(shí)的圖形重生成。首先，對(duì)高速鐵路相關(guān)規(guī)范及測(cè)量技術(shù)進(jìn)行研究，明確了高鐵平面軌道線的基本線形組成及平面線形控制的主要參數(shù)及標(biāo)準(zhǔn)。其次，詳細(xì)分析了設(shè)計(jì)數(shù)據(jù)的數(shù)據(jù)格式，對(duì)設(shè)計(jì)數(shù)據(jù)進(jìn)行了預(yù)處理，給出了便于計(jì)算機(jī)重生成時(shí)的格式。再次，對(duì)VTK技術(shù)框架進(jìn)行研究，給出了用于高鐵軌道線下任意點(diǎn)核檢時(shí)具體的直線線形、圓曲線線形及緩和曲線線形VTK模型。最后，在VS2010平臺(tái)，編寫(xiě)測(cè)試程序，通過(guò)導(dǎo)入實(shí)際在建項(xiàng)目設(shè)計(jì)數(shù)據(jù)，對(duì)所建VTK模型進(jìn)行驗(yàn)證，圖形重生成的結(jié)果和設(shè)計(jì)單位設(shè)計(jì)圖平面線形部分完全吻合。
