An object is to recognize an instrument mismatch with respect to a use situation of a user for a surveying instrument. An information processing device includes an input information creating unit configured to collect information stored in each surveying instrument from a plurality of surveying instruments, and create learning data by associating surveying instrument information, information on measuring function, and information on measuring amount; and a learning model generating unit configured to execute machine learning by using the learning data, and when information on object measuring function and information on object measuring amount used in an object surveying instrument owned or managed by the user are input, generate a learning model for estimating suitable surveying instruments with respect to the information on object measuring function and the information on object measuring amount.
