An assessment device generates, based on a captured image captured by an image capturing device mounted on a moving object, shape information on subjects included in the captured image. The assessment device acquires, by referring to a storage, shape information on a static object associated with the image capturing location. The assessment device specifies, based on the generated shape information and the acquired shape information, a dynamic object that is moving from among the subjects included in the captured image and conducts an assessment related to the dynamic object based on the location in the captured image.
