ABNORMALITY DETECTING DEVICE, ABNORMALITY DETECTING PROGRAM AND ABNORMALITY DETECTING SYSTEM

To suppress an excessive detection.SOLUTION: An abnormality detecting device as an example of the present disclosure includes: an acquisition processing unit that acquires a plurality of picked-up images picked up by an image pickup device in such a way that an object is imaged at respective different positions or postures in a scheme such that a relative position between the image pickup device and the object in each of the plurality of picked-up images or the posture relation is identifiable; an extraction processing unit that extracts, from the plurality of picked-up images, a plurality of abnormality candidate images in which an abnormality candidate is imaged which is possibly corresponding to an abnormality on a surface of the object; an estimation processing unit that estimates a depth relative to the surface of the object of the abnormality candidate in each of the plurality of abnormality candidate images on the basis of a change in the abnormality candidate among the plurality of abnormality candidate images; and a detection processing unit that detects whether or not the abnormality candidate corresponds to the abnormality on the basis of the depth of the abnormality candidate in each of the plurality of abnormality candidate images.SELECTED DRAWING: Figure 3 【課題】過検出を抑制する。【解決手段】本開示の一例としての異常検出装置は、対象がそれぞれ異なる位置または姿勢で写りこむように撮像装置により撮像された複数の撮像画像を、当該複数の撮像画像の各々における撮像装置と対象との相対的な位置または姿勢の関係を特定可能な態様で取得する取得処理部と、複数の撮像画像から、対象の表面の異常に該当する可能性がある異常候補が写りこんでいる複数の異常候補画像を抽出する抽出処理部と、複数の異常候補画像の間における異常候補の変化に基づいて、複数の異常候補画像の各々の異常候補の対象の表面に対する深度を推定する推定処理部と、複数の異常候補画像の各々の異常候補の深度に基づいて、異常候補が異常に該当するか否かを検出する検出処理部と、を備える。【選択図】図３
