Abstract:

Computer vision is an interdisciplinary field that deals with how computers can gain high-level understanding from digital images or videos. From the perspective of engineering, it seeks to automate tasks that the human visual system can do, transformation of pixels into descriptions of the world that can interface with other thought processes and elicit appropriate action. Applications of computer vision include: scene reconstruction, event detection, video tracking, object recognition, object pose estimation, learning, indexing, motion estimation, and image restoration.

 

This presentation reports on recent research on the use of computer vision to monitoring of civil infrastructure.  Applications explored include crack detection in concrete structures, automatic structural damage classification, structural response monitoring, and motion magnification. Finally, the potential use of existing commercial UAVs and cameras to measure the displacement of the railroad bridges under in-service train loads is considered. These studies demonstrate the tremendous potential of computer vision to help in managing a nation’s civil infrastructure.

 

Brief Bio:

B.F. Spencer, Jr. received his Ph.D. in theoretical and applied mechanics from the University of Illinois at Urbana-Champaign in 1985. He worked on the faculty at the University of Notre Dame for 17 years before returning to the University of Illinois at Urbana-Champaign, where he currently holds the Nathan M. and Anne M. Newmark Endowed Chair in Civil Engineering and is the Director of the Newmark Structural Engineering Laboratory. His research has been primarily in the areas of smart structures, stochastic fatigue, stochastic computational mechanics, and natural hazard mitigation.  He is a Fellow of ASCE, a Foreign Member of the Polish Academy of Sciences, the North American Editor in Chief of Smart Structures and Systems, and the past president of the Asia-Pacific Network of Centers for Research in Smart Structures Technology.
