  • Three-dimensional measuring system, and three-dimensional measuring method
    Patent number: 11365959
    Abstract: The three-dimensional measuring method includes: a conveying step of conveying a workpiece to be measured by a robot arm configured to change an attitude of the workpiece; a measuring step of performing three-dimensional measurement on the workpiece by a probe configured to be movable relative to the surface plate in a state in which the workpiece is held by the robot arm; a relative-position change detecting step of detecting a change in a relative position between the surface plate and the robot arm; and a vibration correcting step of correcting a result of the measurement performed on the workpiece in the measuring step based on a result of detection performed in the relative-position change detecting step.
