1. An information processing method executed by processing circuitry, the method comprising:
acquiring a captured image and acquiring, by a sensor, actual altitude information at which the captured image is captured;
detecting a feature of a target object in the captured image;
determining a size of the target object on a basis of a combination of the detected feature and the actual altitude information; and
detecting, with circuitry, whether the target object is a predetermined object based on the actual altitude information and the determined size of the target object.
