Abstract


With China's highway infrastructure construction investment increased scale, Highway Test will be more onerous. In order to solve the problem of heavy highway geometric parameters of real-time field data collection and inspection tasks, road geometry parameters online fast automatic detection technology research and development of hot pavement detection technology. The purpose of this article based online fast automatic detection characteristics for highway geometric parameters of its detection algorithm specific research and selection of specific sensors, the use of modern computer technology, sensor technology, data processing technology and database technology and other high-tech Research highway geometric parameters of fast automatic detection system. In this study, the focus the highway geometric parameters of fast automatic detection theory and its detection algorithm analysis, program design and feasibility analysis, automatic detection system development research, and related experiments, the objective is to develop practical road geometry parameter automatic detection system to lay the basis of a certain technology. The specific contents are as follows: firstly the highway geometric parameters of the concept and its testing standards analysis and research, highway geometric parameters of fast automatic detection system based on the design of the system functional design and testing program, to build the entire automatic detection the framework of the system, including system platforms constitute automatic detection system, power supply system design and automatic detection system equipment installation design, and highway geometric parameters of automatic detection algorithm research. Secondly, a modern object-oriented software development process, UML modeling techniques and the use of the geometric parameters of the entire road detection system modeling, including the entire system needs analysis, systems analysis and design, system implementation, and software testing. Describe their needs in the process of the whole system, analysis of the use cases, the establishment of a conceptual model of the system, the system interaction diagram, system design class diagrams, system state diagram and system architecture, and ultimately the system and system software were testing. Finally, build a system experiment platform the highway geometric parameters automatically detect a large number of repeated experiments, including static experiments and dynamic experiments. The experimental results show that the highway geometric design parameter automatic detection algorithm is feasible, the research and development of the entire system is reasonably available.
