1. An information processing apparatus comprising at least one processor configured to:
- calculate a flow of a collection of objects in a capturing range of a fixed camera using a first surveillance image, the first surveillance image being generated by the fixed camera, the fixed camera being a camera a position of which is fixed;
calculate a distribution of an attribute of objects in a capturing range of a moving camera using a second surveillance image, the second surveillance image being generated by the moving camera, the moving camera being a camera a position of which is not fixed; and
estimate the distribution of the attribute of the objects for an estimation range including a range not included in the capturing range of the moving camera based on the distribution of the attribute of the objects in the capturing range of the moving camera and the flow of the collection of objects in the capturing range of the fixed camera.

Abstract
An information processing apparatus (2000) includes a first analyzing unit (2020), a second analyzing unit (2040), and an estimating unit (2060). The first analyzing unit (2020) calculates a flow of a crowd in a capturing range of a fixed camera (10) using a first surveillance image (12). The second analyzing unit (2040) calculates a distribution of an attribute of objects in a capturing range of a moving camera (20) using a second surveillance image (22). The estimating unit (2060) estimates an attribute distribution for a range that is not included in the capturing range of the moving camera (20).

10. A control method executed by a computer, comprising:
-
calculating a flow of a collection of objects in a capturing range of a fixed camera using a first surveillance image, the first surveillance image being generated by the fixed camera, the fixed camera being a camera a position of which is fixed; calculating a distribution of an attribute of objects in a capturing range of a moving camera using a second surveillance image, the second surveillance image being generated by the moving camera, the moving camera being a camera a position of which is not fixed; and estimating the distribution of the attribute of the objects for an estimation range including a range not included in the capturing range of the moving camera based on the distribution of the attribute of the objects in the capturing range of the moving camera and the flow of the collection of objects in the capturing range of the fixed camera.
