1. A non-transitory computer-readable recording medium having stored therein an estimation program that causes a computer to execute a process comprising:
identifying a first person who uses a first cart from a plurality of first images acquired by capturing inside a store;
generating skeleton information of the first person;
acquiring, by using the skeleton information, a first space in which the first person who grasps a grip part of the first cart, by determining that the first person grasps the grip part, when a variance of a distance between center coordinates of a bounding box of the first person and a bounding box of the first cart in the plurality of the first images captured consecutively is equal to or less than a prescribed threshold; and
estimating a first scale of the first person based on the first space and length information of the first cart.
