| description | To provide an image processing device capable of accurately recognizing the boundary between an inspection surface and a non-inspection surface.SOLUTION: The image processing device includes: a luminance acquisition unit configured to acquire, from an image of an object after processing, luminance data along positions on an inspection surface and a non-inspection surface of the object; a shifting unit configured to shift the acquired luminance data by a predetermined position; a calculation unit configured to calculate a product of the luminance data and the shifted luminance data; a smoothing processing unit configured to perform smoothing processing on the calculated product; and a recognition unit configured to recognize the boundary between the inspection surface and the non-inspection surface of the object based on a rate of change in luminance data after the smoothing processing.SELECTED DRAWING: Figure 2
【課題】検査面と非検査面との境界を精度高く認識することが可能な画像処理装置を提供することを課題とする。【解決手段】加工後の対象物の画像から、前記対象物の検査面および非検査面における位置に沿った輝度のデータを取得する輝度取得部と、前記取得された輝度のデータを所定の位置だけシフトさせるシフト部と、前記輝度のデータと前記シフトさせた輝度のデータとの積を算出する算出部と、前記算出された積の平滑化処理を行う平滑化処理部と、前記平滑化処理後の輝度のデータの変化率に基づいて、前記対象物のうち検査面と非検査面との境界を認識する認識部と、を具備する画像処理装置。【選択図】図２ |
