本書主要內(nèi)容圍繞3D 計(jì)算機(jī)視覺展開，介紹了相關(guān)的基礎(chǔ)概念、基本原理、典型算法、實(shí)用技術(shù)和應(yīng)用成果。本書可在學(xué)過其姊妹篇《2D 計(jì)算機(jī)視覺：原理、算法及應(yīng)用》后學(xué)習(xí)。本書將從客觀場景出發(fā)到后對場景進(jìn)行理解的全過程分為5 個部分進(jìn)行介紹。第1 部分是圖像采集，介紹了攝像機(jī)標(biāo)定和3D 圖像采集技術(shù)；第2 部分是視頻運(yùn)動，介紹了視頻圖像和運(yùn)動信息，以及對運(yùn)動目標(biāo)進(jìn)行檢測和跟蹤的技術(shù)；第3 部分是物體重建，介紹了雙目立體視覺和單目圖像恢復(fù)技術(shù)；第4 部分是物體分析，介紹了3D 目標(biāo)表達(dá)和廣義匹配；第5 部分是高層理解，介紹了知識和場景解釋及時空行為理解。本書除提供大量示例外，還針對每章的內(nèi)容提供了自我檢測題（含提示并附有答案），并且給出了相關(guān)的參考文獻(xiàn)和術(shù)語索引（包括英文）。

本書是一本介紹3D 計(jì)算機(jī)視覺基本原理、典型算法和實(shí)用技術(shù)的專業(yè)圖書，建議讀者在學(xué)習(xí)《2D 計(jì)算機(jī)視覺：原理、算法及應(yīng)用》后使用本書。
本書在選材上主要覆蓋了計(jì)算機(jī)視覺的進(jìn)階級內(nèi)容，自成體系，主要針對信息類相關(guān)專業(yè)，同時兼顧了具有不同專業(yè)背景的學(xué)習(xí)者及自學(xué)讀者的需求。讀者可據(jù)此開展科研工作并解決實(shí)際應(yīng)用中一些具有一定難度的問題。
本書在編寫上比較注重實(shí)用性，沒有過多強(qiáng)調(diào)理論體系，盡量減少公式推導(dǎo)，著重介紹常用的方法。書中有較多的示例，能通過直觀的解釋幫助讀者理解抽象的概念。書末附有術(shù)語索引（文中標(biāo)為黑體），給出了對應(yīng)的英文，方便讀者查閱及搜索相關(guān)資料。
本書提供了大量的自我檢測題（包括提示和答案）。從目的來說，一方面，這便于自學(xué)者判斷自己是否掌握了重點(diǎn)內(nèi)容；另一方面，這便于教師開展網(wǎng)絡(luò)教學(xué)，在授課時加強(qiáng)師生互動。題目類型為選擇題，可用計(jì)算機(jī)方便地判斷正誤。從內(nèi)容來看，很多題把基本概念換一種說法進(jìn)行表達(dá)，補(bǔ)充了正文，使學(xué)習(xí)者能加深理解；有些題列出了一些相似但不相同（甚至含義相反）的描述，通過正反辯證思考，使學(xué)習(xí)者能深入領(lǐng)會本質(zhì)。所有自我檢測題都附有提示，讀者可獲得更多的信息以進(jìn)一步理解題目的含義。同時，在有提示的基礎(chǔ)上，如果讀者能在看到提示后完成自我檢測題，則表明基本掌握了學(xué)習(xí)內(nèi)容；如果不看提示就能完成自我檢測題，則表明內(nèi)容掌握得比較好。
本書從結(jié)構(gòu)上看，包括12 章正文、1 個附錄及自我檢測題、自我檢測題答案、參考文獻(xiàn)和術(shù)語索引。在這17 個一級標(biāo)題下，共有66 個二級標(biāo)題（節(jié)），再之下有135 個三級標(biāo)題（小節(jié)）。全書共有文字（包括圖片、繪圖、表格、公式等）50 萬字，共有編了號的圖228 個、表格22 個、公式565 個。為便于教學(xué)和理解，本書給出示例68 個、自我檢測題157 道（全部附有提示和答案）。另外，書末列出了直接相關(guān)的100 多篇參考文獻(xiàn)和用于索引的500 多個術(shù)語（中英文對照）。
本書的先修課程知識涉及三個方面。一是數(shù)學(xué)，包括線性代數(shù)和矩陣?yán)碚�，以及有關(guān)統(tǒng)計(jì)學(xué)、概率論和隨機(jī)建模的基礎(chǔ)知識；二是計(jì)算機(jī)科學(xué)，包括對計(jì)算機(jī)軟件技術(shù)的掌握、對計(jì)算機(jī)結(jié)構(gòu)體系的理解，以及對計(jì)算機(jī)編程方法的應(yīng)用；三是電子學(xué)，包括電子設(shè)備的特性原理及電路設(shè)計(jì)等內(nèi)容。
感謝電子工業(yè)出版社編輯的精心組稿、認(rèn)真審閱和細(xì)心修改。
后，作者感謝妻子何蕓、女兒章荷銘在各方面的理解和支持。
