Abstract

The invention provides an object position determination method and device. The method comprises the steps of using any one of a one-dimensional measurement light target, a two-dimensional measurementlight target and a three-dimensional measurement light target to receive illumination information of a planar laser wave beams covering an observation reference surface from a predetermined adjacent area of at least one observation reference surface; observing illumination information of distance measurement laser beams or sending the distance measurement laser beams, wherein the distance measurement laser beams are used for obtaining the distance from a position reference point to a distance measurement reference point of an object to be measured; determining the position of the object by using the illumination information of the planar laser wave beams and the distance obtained by the distance measurement laser beams to determine the position of the object; or sending the illumination information of the planar laser wave beams and the distance obtained by the distance measurement laser beams to a position determination unit; or sending the illumination information of the planar laserwave beams to the position determination unit and sending the illumination information of the distance measurement laser beams to a distance measurement unit. The precision is high, the reliability is high, the cost is low, and the device is easy to arrange.

Description

Technical field [0001] The invention relates to the field of automatic measurement, in particular to a method and device for determining the position of an object. Background technique [0002] There are a wide range of application requirements for displacement detection and deformation detection of buildings or industrial facilities. Among them, the 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 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; detection of displacement and deformation of rails (rail transit tracks) Including absolute displacement or deformation measurement based on CPIII (Control Point III), or displacement or deformation measurement based on the characteristics of the total station and measuring vehi...
