Abstract

A management apparatus (100) includes: an area computation unit (102) that acquires an area of a displayable region of a display shelf in which a product can be displayed, and computes an area ratio of an area of a non-display region of the display shelf in which the product detected from a captured image is not displayed to the area of the display shelf; a decision unit (104) that decides whether to make a notification according to the area ratio; and a notification unit (106) that makes the notification when it is decided that the notification is to be made.

Claims14

Dependent claims

A management apparatus comprising:

at least one memory storing instructions;
and
at least one processor configured to execute the instructions to:
receive a captured image of a display shelf including a displayable region in which products are to be displayed;
detect the products in the displayable region;
determine, in the displayable region of the display shelf, a non-display region of the display shelf in which no products have been detected, a plurality of shapes of notification target region in the displayable region being stored with a priority order;
determine a shape of the non-display region;
compare the shape of the non-display region to shapes of a plurality of notification target regions in order of priority of the notification target regions until a matching notification target region is identified for which the shape has a degree of coincidence with the shape of the non-display region greater than a predetermined threshold,
wherein once the matching notification target region is identified, comparison of the shape of the non-display region to the shapes of other of the notification target regions that are lower in priority than the matching notification target region is bypassed;
and
output a notification when the matching notification target region has been identified.

A management method performed by a management apparatus and comprising:

receiving a captured image of a display shelf including a displayable region in which products are to be displayed;
detecting the products in the displayable region;
determining, in the displayable region of the display shelf, a non-display region of the display shelf in which no products have been detected, a plurality of shapes of notification target region in the displayable region being stored with a priority order;
determining a shape of the non-display region;
comparing the shape of the non-display region to shapes of a plurality of notification target regions in order of priority of the notification target regions until a matching notification target region is identified for which the shape has a degree of coincidence with the shape of the non-display region greater than a predetermined threshold,
wherein once the matching notification target region is identified, comparison of the shape of the non-display region to the shapes of other of the notification target regions that are lower in priority than the matching notification target region is bypassed;
and
outputting a notification when the matching notification target region has been identified.

A non-transitory computer-readable storage medium storing a program for executable by a computer to perform processing comprising:

receiving a captured image of a display shelf including a displayable region in which products are to be displayed;
detecting the products in the displayable region;
determining, in the displayable region of the display shelf, a non-display region of the display shelf in which no products have been detected, a plurality of shapes of notification target region in the displayable region being stored with a priority order;
determining a shape of the non-display region;
comparing the shape of the non-display region to shapes of a plurality of notification target regions in order of priority of the notification target regions until a matching notification target region is identified for which the shape has a degree of coincidence with the shape of the non-display region greater than a predetermined threshold,
wherein once the matching notification target region is identified, comparison of the shape of the non-display region to the shapes of other of the notification target regions that are lower in priority than the matching notification target region is bypassed;
and
outputting a notification when the matching notification target region has been identified.
