Speaker: Dr. JungHyun Han, Professor of the Computer Science Department, Korea University
Faculty Host: Jian Tao, PVFA/TAMIDS
Abstract: In this seminar, Prof. Han will present two projects which his students are working on. One is on flow visualization of His lab is developing a mobile AR system for visualizing airflow and temperature changes made by air conditioners, where 3D mapping and virtual air-conditioner installation are made interactively, and then airflow/temperature simulation and visualization are made in real-time. The system is designed in a client-server architecture, where the server is in charge of simulation and the rest is taken by the client. The system is now able to handle real-world air conditioners.
Currently, it is a norm to design a semiconductor fab using 3D building information models (BIMs). Prof. Han’s lab is developing a 3D model-based camera tracking method, which is targeted at navigating a fab’s wide indoor environment. The key observation made in designing the method is that there are a number of fixed objects in such an indoor environment. The columns are representative of them. The proposed method extracts the columns from the input image and matches them to their BIMs to estimate the camera pose. The system can be used in many applications such as AR-based visual inspection.
Biography: Dr. JungHyun Han is a professor in the Department of Computer Science and Engineering at Korea University, where he directs the Interactive 3D Media Lab, the Next-gen VR/AR Research Institute, and the Superintelligence Research Center. Prior to joining Korea University, he worked at the School of Information and Communications Engineering of Sungkyunkwan University in Korea, and also at the Manufacturing Systems Integration Division of the US Department of Commerce National Institute of Standards and Technology. He received a BS degree in Computer Engineering from Seoul National University, an MS degree in Computer Science from the University of Cincinnati, and a PhD degree in Computer Science from the University of Southern California.
