Method for monitoring bridge fault on basis of video image

Abstract

The invention discloses a method for monitoring a bridge fault on the basis of a video image and belongs to the technical field of a bridge monitoring method. The method is characterized by comprising the following steps of: (1) obtaining a video data of a preset position on a bridge; (2) comparing the video data; (3) obtaining a bridge fault condition; and (4) evaluating the use condition of the bridge and early warning. The invention aims to provide a high-detection-efficiency, high-accuracy and low-cost method for monitoring the bridge fault on the basis of the video image. The method is used for monitoring the bridge fault in real time.

Description

technical field [0001] The present invention relates to a bridge monitoring method, in particular to a bridge disease monitoring method based on video images. Background technique [0002] At present, the total amount of highway construction in my country has achieved leapfrog growth, and the overall tension in transportation has been eased. The number of bridges and viaducts that have been built is huge, and the workload of bridge disease acquisition is large. At present, bridge inspections are time-consuming and laborious. Because the low detection efficiency affects the smooth flow of traffic. [0003] The problems existing in the current technology are: the contact-type manual direct measurement method is usually used, which is time-consuming and labor-intensive, and it is difficult to accurately measure the width, perimeter and area of ​​bridge cracks, which affects the accurate assessment of bridge diseases. Contents of the invention [0004] The purpose of the prese...
