To detect an attachment at an early stage.SOLUTION: An attachment detection device according to an embodiment includes a calculation unit and a determination unit. The calculation unit calculates a score of a divided area obtained by dividing a predetermined target area based on the edge intensity in each pixel area of an image imaged by an imaging device. The determination unit determines whether or not the target area is an attachment area in which an attachment adheres to a lens of the imaging device based on the score calculated by the calculation unit.SELECTED DRAWING: Figure 2
【課題】付着物を早期に検出すること。【解決手段】実施形態に係る付着物検出装置は、算出部と、判定部とを備える。算出部は、撮像装置によって撮像された撮像画像の各画素領域におけるエッジ強度に基づいて所定の対象領域を分割した分割領域のスコアを算出する。判定部は、算出部によって算出されたスコアに基づいて対象領域が撮像装置のレンズに付着物が付着した付着物領域か否かを判定する。【選択図】図2
