1. An information processing device comprising:
at least one processor configured to:
for each of a plurality of images of an object to be measured, calculate, as a first length calculation value, a length between parts set for measuring a length of the object, from a corresponding image of the plurality of images, to yield a plurality of first length calculation values respectively corresponding to the plurality of images, wherein the plurality of images are captured by an image capturing device at different capture time points within a set time range; select a plurality of second length calculation values from the plurality of first length calculation values, based on attitude information of the object, such that the plurality of second length calculation values do not include all of the plurality of first length calculation values, wherein the attitude information is information about a rotation angle of the object, the rotation angle of the object being set such that the rotation angle of the object increases as a difference between a first distance and a second distance increases, the first distance being a distance between a first part of the parts and the image capturing device, the second distance being a distance between a second part of the parts and the image capturing device;
select, in accordance with a selection rule that is pre-assigned, one or more of the plurality of second length calculation values under an assumption that the object is in a basic attitude for length measurement; and
determine a measured value of the length of the object using the selected one or more of the plurality of second length calculation values.
