バイラテラル最小値フィルタとバイラテラル最大値フィルタを用いた航空機搭載レーザスキャナデータからの地面抽出

We propose a ground point extraction method from airborn laser scanner data by using bilateral minimum and bilateral maximum filters. The ground point can take advantages of such as inundation inside a levee, inundation by river water, and tsunami simulations. Through experiments which is used airborn laser scanner data of area with inclination, slope, buildings, and plants, we verify the effectiveness of oure method. Finally we comment on the respects in which our method is improved and on future prospects.
