Outline of Final Research Achievements

The aim of this study was to understand the geological differences, which are undetectable by the human eye using a light camera (liquid crystal tunable filter, LCTF, camera capable of capturing images at a wavelength interval of 1 nm from 600 to 1050 nm) that can be mounted on an unmanned aerial vehicle (UAV). I examined a method to assess the mineral content in the ground surface that causes sediment-related disasters by differentiating the mineral content comprising the geology. Aerial photography, which is conducted by mounting the LCTF camera on an UAV, can be used to interpret the geology and estimate the mineral content in areas associated with sediment-related disasters that are at a risk of secondary disasters or require extensive surveys.

Academic Significance and Societal Importance of the Research Achievements

本研究成果は,人が足を踏み入れることが困難な土砂災害地において,無人航空機による空撮により,その原因となったであろう地質を即時的に判断することができる技術革新研究であり,土砂災害の多い我が国において先陣を切って調査研究する学術的意義は大きい.この技術は即時的な技術でもあるが,広範囲の現地調査が可能であるという特性もあるため,2次被害を抑える効果と,砂防対策工事の効率化にも貢献することができるためその社会的意義も大きい.
