An image data acquisition monitoring system for the suspended piping that is difficult to inspect visually above the ceiling, is developed to evaluate the building functionality immediately after an earthquake disaster. The proposed sensor unit consists of an infrared camera for collecting image data and an accelerometer for triggering image data acquisition. The image analysis method based on a single image is presented to estimate the seismic residual deformation in the suspended piping. The proposed image monitoring system is applied to the shaking table test of a full-scale steel frame structure with building equipment at the E-Defense facility.
