Abstract
Disclosed is a laser surveying system in which devices installed at measuring points are inexpensive and small in weight, and a distribution of codes is not needed for transmitting positional data obtained, this system being capable of continuously quickly making a three-dimensional measurement of the displacement. When the laser beam projected from a light projector sweeps a reflecting device on an object, reflecting surfaces supply the laser beam with positional data. A displacement of the object is measured based on the transmitted positional data from the reflected laser beam.
