Method for measuring bridge deformation through multi-camera networking on shaking ship body

Abstract

The invention provides a method for measuring bridge deformation through multi-camera networking on a shaking ship body, and the method comprises the steps: carrying out the image collection of the side surface of a bridge through a plurality of long-focus cameras on the ship, and obtaining a local marking line image; and carrying out deblurring processing on the local marker line image with motion blur, then carrying out image splicing, extracting a complete horizontal marker line, and obtaining a bridge deformation condition based on the extracted complete horizontal marker line, wherein the long-focus camera adopts a coding exposure mode. According to the method, the corresponding points on the motion trail at the exposure moment during the exposure period of the telephoto camera can be accurately found based on the motion speed and the motion direction of the ship body, so that the motion blurred kernel is obtained according to the found track points, the blurred image is subjected to clear restoration, and clear image data is provided for subsequent calculation of the deformation condition of the bridge.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for measuring bridge deformation with a multi-camera network on a swaying hull. Background technique [0002] At present, the measurement of bridge deformation is mostly concentrated in the laboratory simulation scene, but the simulation results cannot fully represent the real test results. When measuring bridge deformation in real scenes, traditional monitoring technologies are often used. However, the deformation monitoring of bridge facilities by traditional technical means is mainly based on the point model, which cannot fully reflect the overall deformation of the bridge. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a method for measuring bridge deformation by multi-camera networking on a shaking hull, the method comprising: [0004] There are continuous horizontal marking lines on the side of the bridge. ...
