Hirohiko Yanagita has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Three-dimensional (3-D) coordinate measuring method, 3-D coordinate measuring apparatus, and large-structure building method
    Patent number: 6559931
    Abstract: A 3-D coordinate measurement is performed in such a way that an electrooptical distance-measuring device is used to measure a linear distance to a target point set on a surface of a measurement object, an angle measuring device is used to measure shifted angles of an optical axis of the electrooptical distance-measuring device, and a 3-D coordinate of the target point is measured according to a measured distance and a measured angle after the optical axis of the electrooptical distance-measuring device has been aligned to the target point.
