To provide an attachment detection device and an attachment detection method, capable of detecting an attachment with high accuracy.SOLUTION: An attachment detection device according to an embodiment includes an extraction unit, a selection unit, and a determination unit. The extraction unit extracts a candidate area of an attachment area corresponding to the attachment adhered to an imaging device based on the edge detected from each pixel of an image imaged by the imaging device. The selection unit selects, as a selection area, the candidate area where the area size and a luminance summary value satisfy a predetermined condition among candidate areas extracted by the extraction unit. The determination unit determines whether or not the selection area is the attachment area based on the unevenness of the luminance distribution of the pixel included in the selection area selected by the selection unit.SELECTED DRAWING: Figure 2
【課題】付着物を高精度に検出することができる付着物検出装置および付着物検出方法を提供すること。【解決手段】実施形態に係る付着物検出装置は、抽出部と、選択部と、判定部とを備える。抽出部は、撮像装置で撮像された撮像画像の各画素から検出されるエッジに基づき、撮像装置に付着した付着物に対応する付着物領域の候補領域を抽出する。選択部は、抽出部によって抽出された候補領域のうち、領域サイズおよび輝度要約値が所定の選択条件を満たす候補領域を選択領域として選択する。判定部は、選択部によって選択された選択領域に含まれる画素の輝度分布の起伏に基づいて選択領域が付着物領域であるか否かを判定する。【選択図】図2
