The Design And Implementation Of Three-dimensional Detection Software System Of Cement Concrete Pavement Joint Faulting Based On VC++

With the vigorous development of the transportation, cement concrete pavement has beenwidely used in our country. Because of the influence of various natural factors, the pavementappeared different degrees disease. All these have bad effects on the quality and safety oftraffic. Joint faulting is a kind of pavement disease. The existence of the joint faulting willsignificantly reduce the service life of pavement and break the comfort of driving. This paperis based on the digital image technology, aims to develop a software system ofthree-dimension detection about cement concrete pavement joint faulting.In view of the present stage detection method on the Joint faulting of cement concretepavement, based on laser triangulation method, combined the properties of the cementconcrete pavement, this paper puts forward a method to measure Joint faulting using the areaarray camera combines linear laser detection technology, design and realize thethree-dimensional test software system of cement concrete pavement‘s joint faulting based onVC++and SQL Server2005.This paper, puts forward the overall design of three-dimensiondetection of cement concrete pavement joint faulting，the design of hardware system andsoftware system firstly, then shows the development platform(Visual Studio2008and SQLServer2005)and the key technologies(database technology, crystal reports technology andmulti-threading technology) used in development of software, gives the structure andfunctional module of the three-dimension detection of cement concrete pavement jointfaulting software system, and the design and implementation of each functional module lastly.Completed the function design requirements of the data acquisition,storage, analysis,three-dimension digital display of the joint faulting of cement concrete pavement, thecheck of joint faulting detection records, the printing of statistics and report.The three-dimension detection system of cement concrete pavement joint faultingdesigned in this paper improves the pavement testing efficiency and precision. It can providescientific and objective based data for the quality evaluation after the roads are built and putinto use, as well as the establishment of road conditions digital information.
