Emitting method and device for detection beam of relative position of object

Abstract

The invention provides an emitting method and device for a detection beam of relative position of an object. The method comprises the steps of emitting a planar laser beam through a first reference point corresponding to a first reference position, so that different parts of the planar laser beam respectively irradiate a second reference point corresponding to a second reference position and a third reference point corresponding to a third reference position simultaneously; acquiring irradiation position information of the planar reference laser beam on the second reference point and the threereference point respectively by using a first and a second reference light targets, and adjusting at least one of the irradiation direction and the normal direction of the beam surface of the planarlaser beam according to the irradiation position information, so that irradiation position errors of the planar beam on the second reference point and the third reference point are less than a predetermined reference plane error threshold. The emitting method has the advantages of being high in precision and reliability, low in cost and easy to deploy.

Description

technical field [0001] The invention relates to the field of automatic measurement, in particular to a method and device for transmitting light beams for detecting relative positions of objects. 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 displacemen...
