Title:
FOREIGN MATTER DETECTION METHOD, FOREIGN MATTER DETECTION SYSTEM AND PROGRAM
Document Type and Number:
Japanese Patent JP2022122072
Kind Code:
A
Abstract:
To accurately detect a foreign matter in liquid by imaging a container storing liquid, setting a plurality of regions in a photographed image of the container, and efficiently removing noise by changing a noise removal capability of a filter to be applied according to a portion of the container and a time zone in which the container is imaged.SOLUTION: A foreign matter detection method comprises: an imaging process of imaging a container made of a translucent material storing liquid; an image processing process of performing filter processing on the photographed image of the container; and a detection process of detecting a foreign matter contained in the container on the basis of the image subjected to the filter processing. The image processing process sets a plurality of inspection regions on the photographed image of the container, sets the plurality of time zones on the basis of the timing at which the container is imaged, and sets a filter having a noise removal capability in a plurality of inspection regions for each of the plurality of time zones.SELECTED DRAWING: Figure 13
