【摘要】：为了解决当前交通监控系统智能化程度低,缺少定位功能的问题,设计并实现了交通肇事车辆快速视觉定位系统。系统采用OV7740图像传感器采集现场车辆图像,通过核心为S3C2410X的图像采集终端接收OV7740图像传感器中的车辆图像数据,并对车辆图像进行存储和显示。采用肇事车辆定位分析模块,对车辆图像进行分析,判断是否存在肇事车辆,实现肇事车辆图像的定位。利用主控芯片为CY7C68013A的控制传输模块,将肇事车辆图像数据变换成USB数据格式,再将图像数据反馈给人机交互模块进行存储和管理。在软件设计过程中,详细分析了交通肇事车辆定位流程,并给出USB设备数据结构以及INF文件配置的程序代码。实验结果表明,所提系统具有较高的定位精度。
[Abstract]:In order to solve the problem of low intellectualization and lack of positioning function in the current traffic monitoring system, a rapid visual positioning system for vehicles causing traffic accidents is designed and implemented. The system adopts the OV7740 image sensor to collect the scene vehicle image, receives the vehicle image data from the OV7740 image sensor through the image acquisition terminal with the core S3C2410X, and stores and displays the vehicle image. The location analysis module is used to analyze the image of the vehicle to determine whether there is a vehicle causing the accident and realize the location of the image of the vehicle caused by the accident. Using the main control chip as the control transmission module of CY7C68013A, the image data of the vehicle caused by the accident is transformed into USB data format, and then the image data is fed back to the human-computer interaction module for storage and management. In the process of software design, the flow of vehicle location caused by traffic accident is analyzed in detail, and the data structure of USB equipment and the program code of INF file configuration are given. The experimental results show that the proposed system has high positioning accuracy.
