Application of video monitoring technology in the field of safety monitoring of bridge and tunnel

In recent years, with the development of electronic information technology, video monitoring technology has been widely used in the safety monitoring of bridge and tunnel operation, but there are still same problems. Video monitoring technology is an important part of the safety monitoring of bridge and tunnel operati9on, and the research on this part still needs to be further improved. At present, there are some problems in the video monitoring technology. For example, In the tunnel, the video monitoring technology is often disturbed by the external environment, so the effect is not obvious, and the collected video data clarity is not high, so the cracks can't be monitored in real time. The brand and mode of the monitoring equipment are mixed, so during the bridge life the replacement of the new and old monitoring equipment troubles the integration of the system. This paper systematically reviews the development status of video monitoring technology at home and abroad, and discusses the necessity of the safety monitoring of bridge and tunnel structure operation, and also analyses and studies the application of video monitoring technology in bridge and tunnel operation safety monitoring. Finally, this paper points out that how to improve the accuracy of video monitoring and reduce the operating cost of security monitoring is the current challenge and the future development direction.
