  • Measuring system
    Patent number: 7564538
    Abstract: The present invention provides a measuring system, which comprises a surveying device installed at a known point, at least one photodetection device to be installed at a measuring point, and a main arithmetic device; wherein the surveying device projects by rotary irradiation a reference plane forming laser beam including two or more fan-shaped laser beams with at least one of the fan-shaped laser beams tilted and a distance measuring light performs distance measurement by receiving a reflected distance measuring light, and performs communication of the distance measurement data between the photodetection device and the main arithmetic device; wherein the photodetection device calculates an elevation angle with respect to the surveying device based on a photodetection signal issued by receiving the reference plane forming laser beam, calculates an elevation position based on the elevation angle and the distance to the surveying device, and performs communication of distance measurement data and elevation posi
