| Summary: | 碩士 === 正修科技大學 === 營建工程研究所 === 106 === In this study, visible light and thermal imaging cameras are mounted on the unmanned aerial vehicle (UAV) for non-destructive testing of structures. For this, three types of different structures are selected for this study, including 10 monuments in Tainan City, exterior walls of the campus buildings and one solar power plant. In the testing process, visible light photos and thermal images of the structures are first obtained, and then interpretative analysis is performed to identify the positions where the temperature is abnormal, and after that site verification is conducted for the abnormal positions, so as to obtain effectiveness of infrared thermal imaging camera in non-destructive testing of the structures.
Theresults of abnormal temperature distribution are obtained from the 4 roofs of the monuments, exterior walls of 2 buildings and roof-mounted solar panel of the solar power plant.Afterthesite inspection, water leakage, ageing, voids, adhesion failure of wall tiles or equipment failure were not identified in the areas at normal temperature. The problems were identified at the areas at abnormal temperature. The results showedthat the non-destructive testing method can detect defective structures and help reinforce, maintain and manage the structures.
