Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, in t...

Abstract

The invention discloses a bridge deflection change measuring method, device and equipment. A vertical plane is selected or arranged at any position of the bridge as a measuring plane; at least four positioning pieces containing control point images are arranged in the measuring plane; the control point images in all control pieces are not collinear at the same time; the method includes the steps of measuring the standard coordinates of the control points in the control point images in the positioning pieces under a horizontal coordinate system, placing a laser at any position, enabling laser spots emitted by the laser to fall into the measuring plane, placing a camera at any position, and enabling the measuring plane to be located in a shooting view field of the camera. A mode of combining laser indication with camera short-distance imaging is adopted, so that the problems that long-distance imaging is influenced by the atmospheric environment and measurement precision is influenced by postures of the camera can be avoided; through control point imaging processing, the influence of camera shaking on the measurement can be eliminated, and deflection measurement can be flexibly carried out on bridges on the water surface, canyons and other positions. The method is applied to the technical field of measurement.
