Bridge deflection measuring method, device and computer readable storage medium

Abstract

The invention discloses a method for measuring bridge deflection. The measuring device for bridge deflection includes a camera assembly. The method for measuring bridge deflection includes the following steps: determining a deflection detection point; controlling the camera assembly to collect data including the deflection detection point the first image; controlling the camera assembly to move a first distance in a preset direction, and controlling the camera assembly to capture a second image including the deflection detection point; according to the first distance, the first image and the The second image determines the bridge deflection corresponding to the deflection detection point. The invention also discloses a bridge deflection measurement device and a computer-readable storage medium, which can be self-calibrated through the image changes of the deflection feature points and the moving distance collected by the camera component, so as to determine the deflection corresponding to the deflection detection point and realize the deflection The measurement steps are simplified, the difficulty of deflection measurement is reduced, and it can be used in many different measurement environments.

Description

technical field [0001] The invention relates to the field of bridge measurement, in particular to a method, a device and a computer-readable storage medium for measuring bridge deflection. Background technique [0002] The bridge is an important part of the transportation network and has an important position in the national economic life. Therefore, it is extremely important to ensure the safety and reliability of the bridge structure. Deflection is a key performance parameter for evaluating bridge safety. Bridge deflection monitoring is of great significance for understanding the health and working status of active bridges, and provides an important basis for bridge bearing capacity and operating conditions. [0003] When detecting bridge deflection, it is necessary to set up steel wires or set up frames at each detection point, so that the measurement cannot be carried out when there is water under the bridge; It is also unavailable; high bridges across canyons, etc. can...

Problems solved by technology

[0003] When detecting bridge deflection, it is necessary to set up steel wires or set up frames at each detection point, so that the measurement cannot be carried out when there is water under the bridge; It is also unavailable; high bridges across canyons, etc. cannot be directly measured; whether it is to lay out or withdraw measuring instruments, it will be more complicated and time-consuming, so the detection of bridge deflection is very complicated and has higher requirements for the measurement environment
