    • A glass bottle inspecting apparatus is presented which can detect a defect at a specific location of a bottle-mouth portion of a glass bottle. An inspecting apparatus detects a defect of a glass bottle by imaging light from the glass bottle while the glass bottle (2) is illuminated and rotated, and processes the obtained image. A glass bottle inspecting apparatus includes a lighting device (7) disposed at a predetermined position with respect to the glass bottle, a plurality of CCD cameras (11-20) disposed around the glass bottle for imaging a specific part of the glass bottle, an angle detection device (10) for detecting a rotation angle of the glass bottle with respect to a reference position, and an image processor (8) for processing the images obtained by the CCD cameras. The image processor stores rotation angle information detected by the angle detection device in such a manner that the rotation angle information corresponds to the image imaged by each of the CCD cameras.
    • 本发明提供一种玻璃瓶检查装置,其能够检测玻璃瓶的瓶口部的特定位置处的缺陷。 检查装置通过在玻璃瓶(2)被照亮和旋转时对来自玻璃瓶的光进行成像来检测玻璃瓶的缺陷,并处理所获得的图像。 玻璃瓶检查装置包括:设置在相对于玻璃瓶的预定位置的照明装置(7),设置在玻璃瓶周围的多个CCD照相机(11-20),用于对玻璃瓶的特定部分进行成像; 角度检测装置(10),用于检测玻璃瓶相对于基准位置的旋转角度;以及图像处理器(8),用于处理由CCD照相机获得的图像。 图像处理器存储由角度检测装置检测的旋转角度信息,使得旋转角度信息对应于由每个CCD照相机成像的图像。
