Prof. Quang-Cherng Hsu, National Kaohsiung University of Applied Sciences, Taiwan
Dr. Quang-Cherng Hsu currently is a professor of Mechanical Engineering, National Kaohsiung University of Applied Sciences (KUAS), Taiwan. Prof. Hsu earned his Ph.D. degree in Mechanical Engineering, National Cheng-Kung University in 1981. After two-year service in military, he joined Metal Industry Research and Development Center, a government fund non-profit research organization, in Kaohsiung as a research engineer about two years. Then, he joined the current University. In 2003~2004, Dr. Hsu visited Ohio State University, U.S.A., as a visiting scholar for one year. During Sept. 12-30, 2016, Prof. Hsu visited Aachen University, German, to study Industry 4.0. From March 3 ~ 26, 2017, Prof. Hsu visited Hung Yen University of Technology and Education, and Hai-Phone University, Viet Nam, and gave intensive speeches. Research interests of Prof. Hsu include Image Processing and Machine Vision, Metal Forming (Forging, Extrusion, Sheet-metal forming), Nano Imprint Lithography Applications, Molecular Dynamics Simulation. During his service at KUAS, Prof. Hsu has published 47 referred journal papers and has attended 26 international conferences among 13 countries to present his research results.
Speech Title: Automatic Optical Inspection and Measurement on Manufacturing
Image processing is processing of images using mathematical operations by using any form of signal processing for which the input is an image, a series of images, or a video, such as a photograph or video frame; the output of image processing may be either an image or a set of characteristics or parameters related to the image. Image analysis can analyze image and to obtain its information and pattern matching uses correlation methods to help solve machine vision problems such as alignment, measurement, and inspection of objects. Image measurement can measure object in one or two or three dimensional ways. By integrating the above technologies and suitable lighting devices, central processing unit (computer) can help us to conduct automatic optical inspection and measurement.
This speech will give a brief introduction about image processing and machine vision. Then, several applications will be present, such as the inspection of dental floss picks, the inspection of bearing, the recognition and measurement of blot, nut and washer, the measurement of large scale spring with different pitch and different diameter, the measurement of sheet metal deformation in order to construct forming limit curve.
