License Plate Recognition Parking Lot Management System to Effectively Solve the Problem of Slow Par

In recent years, with the development of science and technology and the improvement of people's living standards, cars have become a popular means of transportation, and the number of motor vehicles has increased rapidly. The resulting traffic problems are becoming more and more serious. Especially in cities, slow and difficult parking has become a difficult problem perplexing people's daily life. Obviously, if the traditional manual charging method is still used in the parking lot, it is time-consuming and laborious, and it is difficult to manage the vehicles efficiently, and the license plate recognition car parking management system is an effective means. Working principle of car parking management system for license plate recognition 1. Vehicle viewing: various methods such as buried coil viewing, infrared viewing, radar viewing technology and gate video viewing can be used to perceive the passing of vehicles and trigger image collection and capture. 2. Image collection: real time and uninterrupted recording and collection of passing vehicles through HD camera capture host. 3. Preprocessing: noise filtering, automatic white balance, automatic exposure, gamma correction, edge enhancement, contrast adjustment, etc. 4. License plate location: scan the army on the gray image after image preprocessing to determine the license plate area. 5. Character cutting: after the license plate area is located in the image, the character area is accurately determined through gray-scale gate and binarization, and then the character is cut according to the character scale characteristics. 6. Character recognition: the cut characters are scaled and feature extracted to match with the standard character expression in the character database template. 7. Effect output: output the effect of license plate recognition in text format.

Tigerwong license plate recognition system architecture system features built-in optimized embedded license plate recognition algorithm, which can recognize large-angle and large-scale video: the comprehensive recognition rate is higher than 99%; 2 megapixel 1 / 2.8 progressive scanning system with maximum resolution of 1960 * 1080 / 30fps; Built in white list, supporting offline working mode; Intelligent processing of vehicles without license plates: multi trigger mechanism to ensure the normal traffic management of vehicles without license plates (or serious stains, etc.); It supports a wealth of built-in composite pictures and pictures, and can be independently configured with character superposition function to increase recognition and tamper proof; Built in lens: F = 4mm / 6mm / 8mm / 12mm 3MP HD fixed focus lens; Support multiple capture modes: ground induction coil triggers capture; Video detection triggers capture; 2 trigger inputs and 1 control output, which can be directly connected to ground sensing, infrared radiation and gate opening control output; It adopts two-color special light source intelligent fill light mode: day mode and night mode. The brightness value can be adjusted respectively; Supported license plate types: ordinary blue, black, yellow, double-layer yellow, new energy license plate, new armed police license plate, new military license plate, Embassy license plate, Hong Kong and Macao license plate entering and leaving the mainland; Output results: vehicle feature image, license plate image, license plate number, color and passing time; Based on the automatic detection of network heartbeat packet, it can intelligently switch the upper computer or offline control mode when the upper computer crashes; Support RS-485 output identification result information to facilitate the integration of peripheral devices (LED display screen or offline control board, etc.); LCD digital screen display function: electronic shutter, fill light, strong light suppression current value, and the current working state is clear at a glance; Nowadays, the license plate recognition parking lot system is considered to be a set of car parking management system which is more convenient for management and fast traffic. Because it has the advantages of high recognition rate and fast traffic, it is favored by many users. However, car park car park car system is constantly upgrading and functions are increasing. In order to better manage parking lots and parking problems, the license plate recognition technology is certainly not backward.

License plate recognition system will inevitably have huge market and prospect in the Internet plus era trend, and it will also bring convenience to car park system management. Tigerwong parking management system has been inherited for many years! If you have any questions about parking lot system, etc., welcome to consult and exchange.
