Comparison between mobile and PC-side of license plate recognition

License plate recognition is widely used in all aspects, there is a license plate is the application of the car park in the entrance has ever noticed that camera? In the automotive aftermarket, safe city, smart parking and many other industries have a very important position, then you know the principle of license plate recognition?

License plate recognition technology needs to be able to move the car license plate from the complex background to be extracted and identified, through the license plate extraction, image preprocessing, feature extraction, license plate character recognition and other technologies to identify vehicle grade, color and other information. Depth analysis of the difference between the mobile license plate recognition and the PC license plate recognition, the license plate recognition is divided into PC license plate recognition and mobile license plate recognition and server-side license plate recognition.

Mobile License Plate Recognition:

Advantages: Mobile license plate front-end identification software interface is simple and clear, the function of the button clearly understandable, to eliminate any cumbersome operation caused by error-prone problems, suitable for all types of vehicle inspection personnel use. Mobile license plate front-end recognition, can be identified in no network environment, recognition of the speed of the millisecond level, the hardware configuration requirements are low, the software system requirements are low, suitable for most of the platform use. Mobile license plate front-end identification types are also very complete, including blue cards, yellow card (double), military licensing (double), Armed police Licensing (double), police, agricultural license plate, coach license plates, embassies and other specifications of the car license plate. Mobile license plate front-end recognition of the license plate width requirements are low, license plate width ≥ 70 pixels, mobile license plate front-end recognition implanted into the police, handheld toll machine, PAD, mobile phones and other terminals. Android, iOS mobile license plate Recognition SDK can be embedded in the app, through the Android, iOS device camera to the need to manage the vehicle to automatically identify the license plate number, connected to the system, the generated time, the owner information, It's a license plate number. The indispensable tool for front-end acquisition can greatly reduce the workload of management personnel. In fact, whether it is the PC-side license plate recognition or mobile license plate recognition, are through the technical staff time and again research and development, testing, only now so convenient license plate recognition software!

PC-side license plate recognition:
