Hammering test is a widely used for non destructive inspection of concrete structure. It is important for reducing human's burden and time-consumption because there are large and a lot of concrete surfaces which should be inspected. This study introduces development of hammering test support system by displaying the diagnostic results of hammering test via projection mapping. This system detects the hitting positions, analyzes the acoustic data of the hitting sounds, and shows both results on the concrete surface in realtime. We performed the evaluation of the proposed system through the measurement of the accuracy of the hitting positions and its defection on test concrete block. Moreover, we evaluated the proposed displaying method compared with non-support approaches.Through the experiments, we confirmed the effectiveness of the proposed system.
