  • System and method for automatically measuring exhaust area of turbine guide vane
    Patent number: 12013227
    Abstract: A system for automatically measuring an exhaust area of a turbine guide vane, including a data acquisition module configured to measure a three-dimensional point cloud coordinate of a contour of a throat; a positioning module configured to automatically adjust a relative spatial position between the data acquisition module and the turbine guide vane; and a data processing module configured to fit a three-dimensional contour of the throat according to the three-dimensional point cloud coordinate measured by the data acquisition module. A method for automatically measuring an exhaust area of a turbine guide vane using the system is also provided.
