The present invention relates to a glass bottle inspection apparatus which can detect a defect at a specific location such as a bottle-mouth portion of a glass bottle by an imaging process. The glass bottle inspection apparatus includes an inspection unit having one or plural illuminating units (LEDthrough LED) configured to illuminate a glass bottle () and at least one camera (CAMthrough CAM) configured to image light reflected from the glass bottle (), configured to detect a defect at a specific location of the glass bottle. The apparatus has a controller () configured to control operations of the one or plural illuminating units (LEDthrough LED) and the camera (CAMthrough CAM). The controller () controls the one or plural illuminating units (LEDthrough LED) individually to emit a pulsed light in synchronism with an image capturing timing of the camera (CAMthrough CAM).

Glass bottle inspection apparatus and method

The glass bottle inspection method and apparatus performs successively producing differential images from original images successively captured from the glass bottle to be inspected while the glass bottle is being rotated about its own axis, comparing the differential images with the template to judge whether the glass bottle is defect-free or not, and combining all the differential images obtained from the glass bottle to be inspected in one inspection cycle to produce a differential composite image, using the differential composite image as a provisional template when all the differential images obtained from the glass bottle in one inspection cycle are judged as representing a defect-free glass bottle, and correcting the template using the provisional template.
