A malfunction analysis support program causes a computer to perform a log data acquisition step, an action reproduction step, a three-dimensional data display step, a processing step being at least one of a program operation display step, a waveform display step, or a video display step, and a time synchronization step. The log data acquisition step obtains log data temporally sequentially recording a state of an operational part and input-output data of a control signal. The action reproduction step generates action reproduction simulation data obtained by causing a virtual object-to-be-controlled to reproduce an action based on the log data. The three-dimensional data display step displays the action reproduction simulation data as three-dimensional data. The time synchronization step synchronizes time between three-dimensional data displayed by the three-dimensional data display step and data displayed by the processing step. The three-dimensional data display step displays the three-dimensional data according to display setting information.

Malfunction analysis support program storage medium and malfunction analysis support apparatus

A program causes a display data generation apparatus to function as a moving image acquirer that acquires imaging data indicating a moving image of an environment including a device, an estimator that estimates a position and an orientation of an imager capturing the moving image based on an object in the moving image, a log acquirer that acquires log data indicating a log of an operation of the device and an object position corresponding to the object, and a display controller that generates display data for displaying the moving image and a model moving image to be played synchronously. The model moving image is acquired by projecting, at the position and in the orientation, a three-dimensional model of the device placed with respect to the object position while changing the three-dimensional model based on the log.
