The invention relates to a license plate recognition method, a server and a parking charging system. The license plate recognition method comprises the following steps of: acquiring image informationon a parking space; judging whether a vehicle exists on the parking space or not according to the image information on the parking space; if so, judging whether a license plate number of the vehicle on the parking space can be acquired or not by an image acquisition device corresponding to the parking space in advance; and if not, acquiring the license plate number of the vehicle on the parking space by means of a video patrol vehicle. The license plate number of the vehicle is acquired by adopting the image acquisition device corresponding to the parking space. According to the license platerecognition method, if the image acquisition device corresponding to the parking space in advance cannot acquire the license plate number, the video patrol vehicle is linked to acquire the license plate number of the vehicle on the parking space, so that the license plate number of the vehicle on the parking space can be acquired in a double-guarantee manner; and compared with a traditional license plate number acquisition method adopting one mode, two composite and linked license plate number acquisition modes are adopted, so that the license plate recognition accuracy rate can be greatly improved. Therefore, the license plate recognition method can be widely applied to the technical field of parking management.

    本发明涉及一种车牌识别方法、服务器及停车收费系统,它包括获取停车位上的图像信息;根据停车位上的图像信息判断停车位上是否有车辆;若有,则判断通过停车位预先对应的图像获取装置能否获取到停车位上的车辆车牌号;若否,则通过视频巡逻车获取停车位上的车辆车牌号。通过采用停车位对应的图像获取装置获取车辆车牌号。本发明采用若停车位本身预先对应的图像获取装置获取不到车牌号时,联动视频巡逻车获取停车位上的车辆车牌号,双重保障获取停车位上的车辆车牌号,并且相对传统的采用一种形式车牌号获取方式,采用两种复合彼此联动的车牌号获取方式,能够大大提高车牌识别准确率。因此,本发明可以广泛用于停车管理技术领域。
