基于车牌识别的停车场智能收费系统
Intelligent Charging System of Parking Lot Based on License Plate Recognition

为了缓解传统的人工管理停车场方式带来的停车场的管理成本高、效率低，且停车场出入口拥堵这些现象，本文研究并实现了基于车牌识别的停车场智能收费系统。该系统采用SVM算法实现了对进出车库车辆的车牌自动识别，并将相关车辆信息记入数据库，同时显示当前车库的剩余车位。另外，出库时根据查询数据库中的车牌号确定当前车辆是否为VIP用户，进而确定该车辆出库时需要缴纳的费用。本系统的使用很大程度上会减少停车场管理的成本，提高停车场的使用效率。
In order to alleviate the high management cost, low efficiency and congestion at the entrance and exit of the parking lot caused by the traditional manual management of the parking lot, this paper studies and implements the parking lot intelligent charging system based on license plate recognition. The license plate of vehicles can be recognized automatically by use of SVM and can be recorded into the database. Moreover, the remaining parking space in the current parking lot is displayed. In addition, when the vehicle leaves the parking lot, it is determined whether the current vehicle is a VIP user according to querying the license plate number from the database, and then calculates the fees to be paid. The use of this system will greatly reduce the cost of parking lot management and improve the use efficiency of the parking lot.
