Outline of Final Research Achievements

The concrete is an excellent material in the merchantability and the economy. Therefore, it is used for the structure such as bridges. The number of bridges which become superannuated will increase in the future. In this research, the aerial photograph was taken by using Unmanned Aerial Vehicle (UAV). And, 3-dimensional model was constructed with obtained images. Moreover, to detect of the crack by the image processing, it compared with the visual inspection results and image processing results. In addition, Geographical Information System (GIS) was constructed to store the check results.
