Abstract
A laser measuring method in a laser measuring system, which comprises a rotary laser system for projecting a laser beam by rotary irradiation and at least one photodetection system having at least one photodetector for receiving the laser beam, comprising a step of emitting at least two fan-shaped laser beams by the rotary laser system, at least one of the fan-shaped laser beams being tilted, a step of receiving the laser beams at least at three known points by the photodetection system, a step of obtaining elevation angles with respect to the rotary laser system based on photodetection signals which are formed when the photodetector receives the laser beam, and a step of measuring an installing position of the rotary laser system based on elevation angles and position data at the three known points.
