Abstract

An image processing system includes one or more memories storing instructions, and one or more processors executing the instructions to capture images of a predetermined range by using a plurality of image capturing units, generate object shape information based on a plurality of pieces of image data obtained by the plurality of image capturing units, identify a first position and a second position of the object shape information to calculate object range information, acquire predetermined object information containing a position and a shape of a predetermined object, and generate reference area information based on the object range information and the predetermined object information.

Claims (36)

1 . An image processing system comprising:

one or more memories storing instructions; and

one or more processors executing the instructions to:

capture images of a predetermined range by using a plurality of image capturing units,

generate object shape information based on a plurality of pieces of image data obtained by the plurality of image capturing units,

identify a first position and a second position of the object shape information to calculate object range information,

detect a ball object,

acquire object information containing a position and a shape of the ball object,

generate reference area information based on the object range information and the object information,

update a display mode of a reference area that is based on the reference area information,

determine whether the ball object has passed through a range of the reference area, and in a case where the ball object has passed through the range of the reference area, change the display mode of the reference area,

input a result of an umpire judgement, and

change, in a case where the umpire judgement and the determination about passage of the ball object are different from each other, the range of the reference area.

2 . The image processing system according to claim 1 , wherein the reference area is updated to come into contact with the ball object, based on information about a position of the ball object at a time coinciding with a time of the umpire judgement.

3 . A control method for an image processing system, the control method comprising:

capturing images of a predetermined range by using a plurality of image capturing units,

generating object shape information based on a plurality of pieces of image data obtained by the plurality of image capturing units,

identifying a first position and a second position of the object shape information to calculate object range information,

detecting a ball object,

acquiring object information containing a position and a shape of the ball object,

generating reference area information based on the object range information and the object information,

updating a display mode of a reference area that is based on the reference area information,

determining whether the ball object has passed through a range of the reference area, and in a case where the ball object has passed through the range of the reference area, change the display mode of the reference area,

inputting a result of an umpire judgement, and

changing, in a case where the umpire judgement and the determination about passage of the ball object are different from each other, the range of the reference area.

4 . A non-transitory storage medium storing a program for causing an image processing system to execute a control method, the control method comprising:

capturing images of a predetermined range by using a plurality of image capturing units,

generating object shape information based on a plurality of pieces of image data obtained by the plurality of image capturing units,

identifying a first position and a second position of the object shape information to calculate object range information,

detecting a ball object,

acquiring object information containing a position and a shape of the ball object, and

generating reference area information based on the object range information and the predetermined object information,

updating a display mode of a reference area that is based on the reference area information,

determining whether the ball object has passed through a range of the reference area, and in a case where the ball object has passed through the range of the reference area, change the display mode of the reference area,

inputting a result of an umpire judgement, and

changing, in a case where the umpire judgement and the determination about passage of the ball object are different from each other, the range of the reference area.
