商品描述

Digital fringe projection (DFP) techniques are used for non-contact shape measurement of 3D images. In the rapidly expanding field of 3D high-speed imaging, the demand for DFP continues to grow due to the technology's fast speed, flexibility, low cost, and high accuracy.

 

 

High-Speed 3D Imaging with Digital Fringe Projection Techniques discusses the generation of digital fringe with digital video projection devices, covering a variety of core technical aspects. The book begins by establishing the theoretical foundations of fringe pattern analysis, reviewing various 3D imaging techniques while highlighting the advantages of DFP. The author then:

 

 

 

 





     
  •  
  • Describes the differences between digital light processing (DLP), liquid crystal display (LCD), and liquid crystal on silicon (LCoS)




    •  
  •  
  • Explains how to unwrap phase maps temporally and spatially




    •  
  •  
  • Shows how to generate fringe patterns with video projectors




    •  
  •  
  • Demonstrates how to convert phase to coordinates through system calibrations




    •  
  •  
  • Provides a detailed example of a built-from-scratch 3D imaging system

 

 

 

 

Incorporating valuable insights gained during the author's 15+ years of 3D imaging research, High-Speed 3D Imaging with Digital Fringe Projection Techniques illuminates the pathway to advancement in high-speed 3D optical imaging using DFP.

 

 

商品描述(中文翻譯)

數位條紋投影（DFP）技術用於非接觸式三維圖像形狀測量。在快速發展的三維高速成像領域中，由於DFP技術具有快速、靈活、低成本和高精度的特點，對DFP的需求不斷增加。

《使用數位條紋投影技術進行高速三維成像》討論了使用數位視頻投影設備生成數位條紋的方法，涵蓋了各種核心技術方面。該書首先建立了條紋圖案分析的理論基礎，回顧了各種三維成像技術，並突出了DFP的優點。作者隨後：

- 描述了數位光處理（DLP）、液晶顯示器（LCD）和液晶矽（LCoS）之間的差異
- 解釋了如何在時間和空間上展開相位圖
- 展示了如何使用視頻投影機生成條紋圖案
- 示範了如何通過系統校準將相位轉換為坐標
- 提供了一個從頭開始構建的三維成像系統的詳細示例

《使用數位條紋投影技術進行高速三維成像》融合了作者在三維成像研究中獲得的寶貴見解，為使用DFP進行高速三維光學成像的進步提供了指引。

作者簡介

Song Zhang earned his BS from the University of Science and Technology of China, and his MS and PhD in mechanical engineering from Stony Brook University. He then spent three years in the Mathematics Department at Harvard University before joining Iowa State University as an assistant professor of mechanical engineering. He recently moved to Purdue University, where he is currently an associate professor of mechanical engineering. A widely published and highly decorated SPIE fellow, Professor Zhang is often credited with developing the first-ever high-resolution, real-time 3D optical imaging system. Besides being extensively utilized in academia, the technologies Professor Zhang has developed have been used by the rock band Radiohead to create a music video for the 2007 song "House of Cards," and by Zaftig Films to produce the 2015 movie Focus.

作者簡介(中文翻譯)

宋張（Song Zhang）在中國科技大學獲得學士學位，並在Stony Brook大學獲得機械工程的碩士和博士學位。在加入愛荷華州立大學擔任助理教授之前，他在哈佛大學數學系工作了三年。最近，他轉到普渡大學，目前擔任機械工程的副教授。作為一位廣泛發表論文且備受讚譽的SPIE會士，張教授常被認為是開發首個高解析度實時3D光學成像系統的人。除了在學術界廣泛應用外，張教授所開發的技術還被搖滾樂團Radiohead用於創作2007年歌曲《House of Cards》的音樂視頻，以及被Zaftig Films用於製作2015年電影《Focus》。
