Abstract: An information processing device includes an acquisition interface and a processor. The acquisition interface acquires a first detection image obtained by capturing an image of a plurality of target objects including a first target object and a second target object, which is more transparent to visible light than the first target object, using the visible light, and a second detection image obtained by capturing an image of the plurality of target objects using infrared light. The processor obtains a first feature amount based on the first detection image, obtains a second feature amount based on the second detection image, and calculates a third feature amount corresponding to a difference between the first feature amount and the second feature amount. The processor detects a position of the second target object in at least one of the first detection image and the second detection image, based on the third feature amount.
