Person authentication support system, person authentication support method, and non-transitory storage medium

A person authentication support method comprising, by a computer:

• acquiring a measurement condition of a depth in a measurement apparatus capable of generating image information indicating an image of a photographing region including a face of a target person, and depth information indicating a depth;
• setting, in the photographing region, a processing region, which is a region serving as a processing target of the depth information according to the measurement condition,
• wherein the processing region is a region where depth information is acquired;
• acquiring depth information including a depth acquired in the processing region, which is measured in the measurement condition;
• and
• determining whether image information of the target person is used in collation processing, based on depth information of the set processing region.

A non-transitory storage medium storing a program for causing a computer to execute:

• acquiring a measurement condition of a depth in a measurement apparatus capable of generating image information indicating an image of a photographing region including a face of a target person, and depth information indicating a depth;
• setting, in the photographing region, a processing region, which is a region serving as a processing target of the depth information according to the measurement condition,
• wherein the processing region is a region where depth information is acquired;
• acquiring depth information including a depth acquired in the processing region, which is measured in the measurement condition;
• and
• determining whether image information of the target person is used in collation processing, based on depth information of the set processing region.
