Provided are an information processing system, an information processing method, and an information processing program that facilitate generation of a three-dimensional model of a physical object. An information processing system includes at least one processor. The processor is configured to: acquire first information including at least one of information on an object, information on an environment in which the object is imaged or measured, information on a condition under which the object is imaged or measured, or information on importance of imaging or measurement; and generate second information on generation of three-dimensional data of the object based on the first information.
