Zusammenfassung: | To provide an inspection device with which it is possible to reliably discriminate pass or fail of a product that is heat seal packaged.SOLUTION: Provided is an inspection device for inspecting a product that is heat seal packaged. The inspection device comprises: an infrared camera that captures an image of the product; an acquisition unit that acquires a thermography image of the product having been captured by the infrared camera; a first determination unit that determines a center position of the product in the thermography image; a second determination unit that sets a plurality of line segments extending from the center position to an outer circumference of the product in the thermography image, and determines a plurality of inspection regions on the basis of the line segments; a detection unit that detects a peak temperature in the inspection region; a first assessment unit that assesses whether or not the peak temperature is within a prescribed range; and a second assessment unit that assesses whether or not the number or the percentage of the inspection regions whose peak temperatures are assessed to be within the prescribed range by the first assessment unit is greater than or equal to a threshold.SELECTED DRAWING: Figure 1
【課題】 ヒートシール包装された製品の良否を確実に判別することができる検査装置を提供する。【解決手段】 ヒートシール包装された製品を検査する検査装置であって、前記製品を撮影する赤外線カメラと、前記赤外線カメラにより撮影された前記製品のサーモグラフィー画像を取得する取得部と、前記サーモグラフィー画像において前記製品の中心位置を決定する第1決定部と、前記サーモグラフィー画像において前記中心位置から前記製品の外周に向けて延びる複数の線分を設定し、前記線分に基づいて複数の検査領域を決定する第2決定部と、前記検査領域内におけるピーク温度を検出する検出部と、前記ピーク温度が所定範囲内であるか否かを判別する第1判別部と、前記第1判別部において前記ピーク温度が前記所定範囲内であると判別された前記検査領域の数または割合が閾値以上であるか否かを判別する第2判別部とを備える。【選択図】図1 |
