Abstract

The invention provides an optical measuring mark work method and device for photography measurement. The method comprises the following steps of obtaining work triggering information; enabling an optical measuring mark module to be disengaged from an environment protection state through a servo mechanism and to enter a work state; reflecting optical signals or emitting optical signals to an optical image sensor for photography measurement by the optical measuring mark module in the work state; obtaining work termination information; enabling the optical measuring mark module to be disengaged from the work state through the servo mechanism and to enter the environment protection state, wherein the optical measuring mark module is used for being at least arranged on a measured target and being arranged near the measured target. The long-period field arrangement can be realized; the measurement precision is high; the efficiency is high.

Description

technical field [0001] The invention relates to the field of automatic measurement, in particular to an optical measurement mark working method and device for photogrammetry. 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] ...
