Information processing device, mobile body, and learning device

An information processing device, comprising:

• an acquisition interface that acquires a first detection image obtained by capturing an image of a plurality of target objects using visible light and a second detection image obtained by capturing an image of the plurality of target objects using infrared light, the plurality of target objects including a first target object and a second target object, the second target object being more transparent to the visible light than the first target object;
• and
• a processor including hardware,
• the processor being configured to:
• obtain a first feature amount based on the first detection image;
• obtain a second feature amount based on the second detection image:
• calculate a transmission score indicating a degree of transmission of the visible light with respect to the plurality of target objects whose image is captured in the first detection image and the second detection image, based on the first feature amount and the second feature amount,
• calculate a shape score indicating a shape of the plurality of target objects whose image is captured in the first detection image and the second detection image, based on the first detection image and the second detection image, and
• distinctively detect a position of the first target object and a position of the second target object in at least one of the first detection image and the second detection image, based on the transmission score and the shape score.
