EXTRACTION SYSTEM OF SLOPE COLLAPSE SPOT, EXTRACTION METHOD OF SLOPE COLLAPSE SPOT AND EXTRACTION PROGRAM OF SLOPE COLLAPSE SPOT
To provide an extraction system of a slope collapse spot which can extract a collapse spot of a slope at a low cost while enhancing extraction accuracy.SOLUTION: An extraction system of a slope collapse spot comprises: an acquisition unit which is configured to acquire a visible light image of a collapse extraction region on a ground surface and a vegetation index map indicating the distribution of a vegetation index in the collapse extraction region; and an extraction unit which is configured to execute detection processing of detecting a low index region in which the vegetation index is smaller than a threshold in the vegetation index map from the collapse extraction region, and extraction processing of extracting a collapse spot of a slope with pattern matching to a determination object region including the low index region in the visible light image.SELECTED DRAWING: Figure 2
【課題】抽出精度を高めつつ、低コストで斜面の崩壊箇所を抽出できる斜面崩壊箇所の抽出システムを提供する。【解決手段】本開示は、地表における崩壊抽出領域の可視光画像と、崩壊抽出領域における植生指数の分布を示す植生指数マップとを取得するように構成された取得部と、崩壊抽出領域の中から、植生指数マップにおいて植生指数が閾値よりも小さい低指数領域を検出する検出処理と、可視光画像における低指数領域を含む判定対象領域に対するパターンマッチングにより、斜面の崩壊箇所を抽出する抽出処理と、を実行するように構成された抽出部と、を備える斜面崩壊箇所の抽出システムである。【選択図】図２
