软件识别：显而易见词义能理解出来是通过软件对车牌号码进行的，通过在电脑上安装一个配套的车牌识别软件，对抓拍的图片进行识别处理。其工作方式是通过摄像机连续抓拍多张照片，选择其中较为清晰的一张，然后通过电脑软件进行字符处理，实现号牌识别的。因为每次识别需要抓拍多张图片，因此软识别的速度较慢。而且该系统对所抓拍的图片要求也是极高的，必须极为清晰才能达到想要的效果。该系统对现场环境以及调试质量要求极高，在诸多环境不乐观的场合都不适用，设备的摆放颇为重要。
Software Recognition: Obviously, the meaning of words can be understood through software to carry out license plate number, through the installation of a matching license plate recognition software on the computer, to recognize and process the snapped pictures. Its working mode is to take several photos continuously by camera, select one of them which is clearer, and then process the characters by computer software to realize the number plate recognition. Soft recognition is slow because it takes more than one picture to be captured each time. Moreover, the requirements of the system for captured pictures are very high, and it must be very clear in order to achieve the desired effect. The system has very high requirements for the field environment and debugging quality. It is not applicable in many environments where the environment is not optimistic. The placement of equipment is very important
