    摘要: A glass inspection equipment includes a first transfer rail extending in a first direction, where a glass including first sides and second sides extending in a direction intersecting the first sides reciprocates in the first direction, a rotation part on the first transfer rail to rotate the glass, an edge inspection part on the first transfer rail to inspect the first and second sides of the glass, and a surface inspection part which inspects a surface of the glass, the edge inspection part inspects the first sides when the glass with the first sides arranged parallel to the first direction is transferred under the edge inspection part, and the edge inspection part inspects the second sides when the glass transferred through the edge inspection part is rotated by the rotation part and the glass with the second sides parallel to the first direction is transferred under the edge inspection part.

    摘要: A visual inspection system includes a conveyance device conveying an inspection target on a glass plate in a rotating direction of the glass plate, an outer-side-surface image capturing device capturing an image of the inspection target at an outer-side-surface image capturing position, and a judgment device judging based on the captured image whether the inspection target is defective in appearance or not. The outer-side-surface image capturing device has an illumination unit for inspection and three image capturing units arranged around the illumination unit. Each image capturing unit includes first and second mirrors receiving light reflected from an outer side surface of the inspection target at position below the illumination unit, a third mirror reflecting reflected light from the first and second mirrors upward, and an imaging camera arranged above the third mirror.

    摘要: Multiple scans of the same object are obtained, where for any given line on the object to be scanned, the angle of the illumination is different for each scan. The different scans are obtained from different rows of photosensors that are separated. Because the angles of illumination are different, the resulting shadows in each scan are different. The multiple scans may be combined into a single composite color image. In a composite image, a dust particle may generate a series of overlapping shadows, where each shadow is a different color. Searching the composite image for the unique pattern of colors may identify artifacts or defects. Alternatively, the data for one scanned image may be compared to the data for another scanned image, and any differences may be due to shadows, which may indicate defects.
