1、論文題目：地面三維激光掃描技術(shù)及其在歷史建筑數(shù)字化中的應(yīng)用研究專業(yè)：測繪工程碩士生：董洪光(簽名)指導(dǎo)教師：師蕓(簽名)摘要古建筑保護(hù)、修繕是當(dāng)前我國古建筑領(lǐng)域一項重要的研究課題，如何準(zhǔn)確獲取古建筑原始資料是今后進(jìn)行維護(hù)、修繕的前提條件，三維激光掃描技術(shù)的出現(xiàn)為古建筑測繪帶來技術(shù)革新，為更好地實(shí)現(xiàn)古建筑三維信息數(shù)字化提供了新的技術(shù)和方法。本文就三維激光掃描技術(shù)在古建筑數(shù)字化中的應(yīng)用展開研究。文中結(jié)合大雁塔數(shù)字化案例，詳細(xì)探究了三維激光掃

2、描技術(shù)在古建筑數(shù)字化中外業(yè)數(shù)據(jù)采集及內(nèi)業(yè)數(shù)據(jù)處理的流程和方法，制作完成了大雁塔外側(cè)點(diǎn)云模型、實(shí)體模型及真彩色模型，并按照古建筑測繪內(nèi)容制作了大雁塔平面圖、立面圖，最后借助GeomagicStudio軟件平臺，實(shí)現(xiàn)了大雁塔三維可視化。試驗研究表明，三維激光掃描技術(shù)其全自動、高精度、非接觸性，可準(zhǔn)確快速實(shí)現(xiàn)古建筑外業(yè)數(shù)據(jù)采集，結(jié)合日益成熟的點(diǎn)云后處理技術(shù)，可有效實(shí)現(xiàn)古建筑數(shù)字化，獲取古建筑現(xiàn)狀信息，建立古建筑三維模型，用于古建筑保護(hù)。關(guān)鍵詞
