Abstract

The invention provides a light beam switching method and device. The method comprises the steps of receiving irradiation information covering the surface-shaped laser wave beam of an observation reference surface from a predetermined neighborhood of at least one observation reference surface by using any one of a one-dimensional measuring light target, a two-dimensional -dimensional measuring light target, and a three-dimensional measuring light target; and / or observing the irradiation information of range-finding laser beam or sending the range-finding laser beam; completing at least one switching of the surface-shaped laser wave beam and of the range-finding laser beam during the process when the measuring light target moves from the first observation position in the first area to the second observation position in the second area and before the measuring light target moves to the second observation position; accuracy is high, reliability is high, cost is low, and laying is easy.

Description

technical field [0001] The invention relates to the field of automatic measurement, in particular to a beam switching method and device. Background technique [0002] There is a wide range of application requirements for displacement detection and deformation detection of buildings or industrial facilities. Among them, displacement or deformation detection of bridges, dams and rails is an important technical means for safe operation and production. [0003] At present, the methods for detecting the displacement and deformation of dams and bridges include line-of-sight detection, GPS (global navigation system) and the combination of these methods and surface displacement sensors; Including the measurement of absolute displacement or deformation based on CPIII (Control Point III), or the relative displacement or deformation measurement based on total station and measuring vehicle, or the measurement based on displacement sensor. [0004] The line-of-sight method is used to de...
