  • Publication number: 20210118310
    Abstract: Training data required for further training an AI pre-trained model to be used to identify aircraft can be effectively generated. A training data generation method includes: obtaining two data items among an appearance data item on an aircraft in an image in which a specific route has been imaged, a signal data item on radio waves emitted from the aircraft on the route, and a noise data item indicating noise from the aircraft on the route; identifying an attribute of the aircraft on the route by inputting one of the obtained two data items into a first identification model for identifying the attribute of the aircraft; and generating training data used for training a second identification model for identifying the attribute of the aircraft, by associating the other of the obtained two data items with the attribute of the aircraft on the route identified in the identification step.
