A workpiece installation method includes obtaining a reference image that shows a reference workpiece whose posture has been adjusted, setting workpiece reference lines on a boundary of a first image area occupied by the reference workpiece in the reference image, obtaining a measurement image that shows a workpiece, generating, using a processor, a measurement combined image in which workpiece reference lines are superimposed on the measurement image and which shows the workpiece reference lines pass through positions respectively identical to workpiece reference line positions, and adjusting a posture of the workpiece such that a boundary of a second image area occupied by the workpiece in the measurement combined image is shown to be substantially parallel to or substantially coincident with the workpiece reference lines.

A method for detecting a phase on a gear includes obtaining a first determination result indicating whether the gear has been detected at a first detection position. A second determination result indicating whether the gear has been detected at a second detection position is obtained. A third angle between the first and second angles is obtained. A third determination result indicating whether the gear has been detected at a third detection position is obtained. The first angle is replaced with the third angle when the third and first determination results are same, or the second angle is replaced with the third angle when the third and first determination results are different. The phase on the gear is detected based on an angle that is between the first angle and the second angle.
