Image-based Measurement on Guan-Miao Elementary School In-situ School Building Pushover Tests

This paper presents the image-based measurement technology employed for in-situ schoolhouse pushover tests at Guan-Miao Elementary School in Tainan, Taiwan. Image-based measurement adopted in the tests includes collapse paths, column deformations, and foundation deformations. It is suitable for collapse tests due to its multi-axial large deformation, which is difficult to measure by conventional contact measuring devices. The said measurement is a collaboration work among the National Kaohsiung First University of Science and Technology(NFKUST), the National University of Kaohsiung(NUK) and this center. Image analysis technology has been widely applied for image-based measurement at various industrial, medical, and high-technological disciplines. As the improvement of digital camera technology continues, image-based measurement is no longer a high cost and luxury measurement, but an affordable and satisfying solution for practical applications. At high risk regions, image-based measurement is a safe alternative as well compared to direct visual observation. Potential applications on health monitoring and risk region observation may be explored and promoted.
