Abstract

According to an embodiment, the tablet inspection apparatus includes a differential image generation unit for generating a horizontal differential image which is a horizontal differential image of a captured image of a tablet and a vertical differential image which is a vertical differential image. image; an inner product image generation unit that generates an inner product image based on an inner product of a reference image having a vector oriented in a tangential direction to a concentric circle centered on a center position of the tablet, and a horizontal differential image and a front vertical differential image a logical AND image generating unit that generates a logical AND image based on a logical AND of a peripheral mask and the inner product image, the peripheral mask shielding the peripheral portion of the tablet; a threshold image generating unit that generates a threshold image based on a predetermined threshold A threshold image obtained by binarizing the logical AND image; and a judging unit judging whether or not the tablet is defective based on a result of labeling processing on the threshold image.

Description

technical field [0001] Embodiments of the present invention relate to techniques for inspecting tablets. Background technique [0002] Conventionally, in the manufacturing process of pharmaceuticals, it is known that a PTP (Press Through Package: blister packaging) packaging device is used to detect defects such as foreign matter and chipping on the surface of tablets packaged with PTP sheets. In such an inspection, a defect is detected by binarizing an image of a tablet captured by a visible light camera. In addition, in order to emphasize defects of the tablet, a filter such as a Sobel filter or a Laplacian filter is used. [0003] Patent Document 1 is disclosed as a related art. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2012-247376 Contents of the invention [0005] However, according to the method of emphasizing the defect of the tablet using a filter, it is difficult to distinguish the defect from the contour because the contour portion of the table...
