中文摘要: 针对人流密集区域停车场管理效率低下, 停车难的问题, 提出了一种基于车牌字符识别技术的临时停车场自动收费系统. 首先, 通过停车场出入口处的摄像机抓拍车辆图像; 其次, 利用图像处理技术进行车牌定位、车牌矫正、车牌字符分割, 并搭建卷积神经网络实现车牌字符识别; 然后, 通过MySQL 数据库实现车辆进出时间存储、停车时长及收费金额的计算; 最后, 设计了管理显示界面实现车辆信息的管理和显示. 利用OpenCV和C++对整个系统进行了仿真实现. 仿真结果表明, 该系统识别率达到97%以上, 设备移动简便、停车管理自动化程度高, 极大的减轻了临时停车场停车管理难度.
Abstract:An automatic fare collection system for temporary parking lots based on plate number recognition is proposed to resolve parking difficulty and enhance the operation efficiency of the parking lots in densely populated areas. First, cameras at the entrance will take snapshots of vehicles. Subsequently, the system will identify, adjust and split license plate characters with image processing techniques, and then recognize the specific characters through a convolutional neural network. After that, in-out time, duration, and fare will be recorded and calculated in the MySQL database. Finally, an operation dashboard is designed to visualize and manage the system. The whole system is simulated by OpenCV and C++, and results prove a recognition rate of 97% or above. The device is portable with highly automatic operation, greatly facilitating the management of temporary parking lots.
