The revetment in Ota-gawa River in Hiroshima is long structure and it also has many damaged parts, so a work of survey and evaluation, especially visual inspection is spent huge cost and time. An urgent task is the development and application of efficient and easy inspection method. Therefore, we tried to survey and inspect the revetment by Structure from Motion with the Unmanned Aerial Vehicle. We verified about measuring range, shooting procedure measuring accuracy, the time needed to measure and compared the result of this trial, and the last soundness evaluation. Based on their results, we summarized the effectiveness and problems of inspection with UAV for the future application.
