Display data generation program, display data generation device, and display data generation method

The program causes the display data generation device (10) to function as: a moving image acquisition unit (11) that acquires captured data indicating a captured moving image obtained by capturing an environment including the instrument (30); an estimation unit (14) that estimates the position and orientation of an imaging device (20) that captures the captured moving image, on the basis of an object captured in the captured moving image; a log acquisition unit (13) that acquires log data indicating a log of the operation of the instrument (30) when the captured moving image has been captured; a model acquisition unit (12) that acquires model data indicating a three-dimensional model of the instrument (30) and an object position corresponding to the object; and a display control unit (15) that generates and outputs display data for displaying a model moving image and a captured moving image, which are obtained by changing a three-dimensional model in accordance with a log, and displaying the model moving imag
