Research And Development Of Inspection System Of Tied Arch Bridge Based On Image Processing And Machine Vision Technology

Tied arch bridges are widely used in bridge construction.With the rapid development of my country’s economy,the traffic volume is increasing day by day.The early construction of bridges is in overload operation.The inspection and evaluation of the completed tied arch bridges are necessary measures to ensure the normal operation of the bridge.In view of the fact that the existing detection system does not have the ability to directly analyze the disease data,this paper has conducted a study on the non-contact disease detection,data processing and computer system implementation of the tied arch bridge by establishing a set of standardized component division methods.The main research contents and results are as follows:(1)The detection units are divided in detail.Each unit participating in the bridge inspection project has its own way of dividing the detection units.These division methods are not uniform and cannot be directly applied to the developed system.This paper refers to the current domestic standards for bridge inspection and combines with the system requirements,and studies a set of methods suitable for dividing the detection unit and coding of the arch bridge.(2)The design of the overall function of the system,according to the domestic bridge inspection specifications,the various functions of the system are designed for the entire process of the inspection of the tied arch bridge,so that it can achieve non-contact disease detection and the technical status of the full bridge tied bridge Automatic evaluation.(3)The realization of the overall function of the system,using MATLAB to develop the system,realize the intelligent pretreatment of disease pictures,realize the accurate measurement of the disease length,width and area,and realize the non-contact disease detection of the system Function and automatic assessment of the technical status of the full bridge.(4)After debugging the overall functions of the system,after the completion of the various functions of the system design,the system’s non-contact disease detection function and the full bridge technical status automatic evaluation function were tested,and the actual bridge test data and full bridge were compared and analyzed.Bridge technical status.The reliability of the system is verified.
