  • Patent number: 11781856
    Abstract: Convenience is improved by enabling an imaging section to capture an image of a measurement element without adjustment of a rotation angle of a measurement object performed by a user. A control unit identifies a reference rotation angle during measurement, and calculates a measurement angle to measure a measurement element based on a relative rotation angle with respect to the reference rotation angle stored in advance. The control unit controls a rotation unit such that a rotation angle of the rotation unit becomes the measurement angle. The control unit executes a process of measuring a dimension of the measurement element based on a measurement object image captured by an imaging section when the rotation angle of the rotation unit becomes the measurement angle.
