| Accident scene mapping system is used to help China and other countries in the world to handle the traffic police accident scene investigation and mapping of the system software. This system is aimed to establish a graphics drawing system based on vector graph. By the draw and fundamental diagram combined into the scene of the accident of various factors, this paper designs a simple, convenient and easy to use and popular drawing software. This drawing system uses object-oriented ideas, adopts vc6.0 development platform of MFC mechanism, relys on vector graphics rendering technology to implements a subset of drawing function.This paper first introduces the traffic accident situation and problems. Then presents the existing traffic accident treatment process and puts forward the scene of the accident rapid processing methods. Then analyses system development of related techniques. This paper expounds the development environment and develops language, MFC framework and vector chart drawing technology. General design of the traffic accident drawing system is mainly to do detailed demand analysis, draw the function diagram of each module and the function relation graph of system development, and make a detailed introduction to the class and objects used in the System. Detailed design part of the System is the key implementation of system , realize modules and the corresponding function, in order to achieve the goals and complete system of the functional requirements of the system, including each module of the concrete realization and code compiling. Finally, the use method is showed by the specific example about the drawing software scene of the accident.This system can fairly flexible use map library, and can achieve quick and convenient figure library draw. Besides, tagging module (migration distance) digital choice is more convenient. It also can choose all the combined Numbers, which similar to the calculator interface, to make it easy to use. |
