Advantages Comparison Between Soft Recognition and Hard Recognition of License Plate Recognition Sys

With the development of the parking industry, the market is full of a wide range of products, and the demand for license plate recognition system is becoming more and more extensive. It is mainly divided into software recognition and hardware recognition. The license plate recognition system can realize automatic recognition, automatic login and automatic comparison through license plate number detection. The license plate recognition system can realize many intelligent functions, such as automatic gate opening, automatic billing, automatic verification of user vehicle identity, automatic distinction between fixed vehicles and temporary vehicles, automatic calculation of parking spaces and so on. Software recognition: it is obvious that the meaning of the word can be understood through the software.

The captured pictures are recognized, processed and stored through the recognition software on the cloud platform on the computer. Its working principle is to take photos through the camera, and then process characters through computer software to realize number plate recognition. The system has high requirements for the performance of the captured pictures. It must have a very clear picture to achieve the effect. The system not only has high requirements for the on-site environment and debugging quality, but also can not be applied in the situation where the general environment is not optimistic.

Hardware recognition: a series of character processing for the pictures captured by the system through independent hardware equipment; At present, in the parking lot system industry, hardware recognition is also divided into two types, that is, with a separate license plate recognition instrument and front-end hardware recognition. The front-end hardware recognition integrated camera is relatively common. It meets the needs of the market and has been favored by many customers. It is to embed the traditional separate license plate recognition instrument into the camera, realize the integration of front-end hardware and camera, and perfectly realize a series of work such as image capture, video stream transmission, character recognition, gate lifting, etc. Comparison of advantages between soft recognition and hard recognition: 1. Analysis and recognition mode: hard recognition system: video stream analysis and recognition is adopted to conduct all-weather real-time analysis of video streams within the monitoring range; Soft recognition system: image analysis and recognition, take photos of vehicles within the specified range, and then analyze the photos; When the vehicle position is poor, the identification is prone to error. 2. Trigger recognition mode: hard recognition system: ground sense and video trigger are optional. There is no need to add detection equipment, destroy the ground or add projects, and collect images 24 hours a day. Soft recognition system: triggered by ground sensing, infrared and other peripheral vehicle detection equipment; Certain quantities are required. 3. Intelligent algorithm model hard recognition system: intelligent fuzzy dot matrix recognition algorithm is adopted, which has higher accuracy and recognition rate, and basically does not need manual intervention.

Soft recognition system: OCR / font topology recognition algorithm will frequently have false recognition, with low accuracy. It also needs to input the corrected number plate manually. 4. Reliability and stability: hard recognition system: built-in license plate recognition algorithm, which can automatically adjust the camera imaging brightness according to the ambient light to ensure the reliability and stability of the system. Soft identification system: software identification, which is prone to frequent crashes, requires frequent restart of the computer, resulting in intermittent system paralysis. 5. Recognition speed: hard recognition system: the vehicle license plate recognition speed is less than 0.4 seconds, which fully meets the needs of large traffic flow; Soft recognition system: the vehicle license plate recognition speed is greater than 3 seconds or even longer, which is unbearable. 6. Environmental adaptability hard identification system: it can work normally all day under various lighting conditions such as night, cloudy day and rainy day; Soft recognition system: under the above conditions, the recognition accuracy will fluctuate greatly in different periods of the day. 7. Compatibility hard recognition system: without the support of industrial IO card, the control system of the via parking lot can be directly and seamlessly compatible with all kinds of IC, ID, paper ticket and other parking lots, so as to realize the functions of automatic recognition and automatic printing of license plate number when the license plate number and card number must be consistent. Soft identification system: it relies on Io card for vehicle detection, opening and closing of road gates and other actions, which is only embedded in software and has no connection with hardware. Large quantities, many lines and relatively poor stability. 8. Camera sharing hard recognition system: the system can share the camera with the monitoring system without any impact on the system.

Soft recognition system: it cannot be shared, otherwise it will seriously affect the system stability and recognition rate. 9. Output signal hard identification system: the system can output real-time data such as large picture of vehicle, small picture of number plate, number plate identification number, number plate color and identification reliability, traffic flow, parking volume in the yard, etc. It has the function of static picture query for vehicle access, connecting parking space guidance system, etc. Soft recognition system: it has no output interface and is basically used by the system itself. It is unable to carry out secondary development. The license plate recognition system carries out real-time online management of vehicles entering and leaving the parking lot to improve the parking efficiency of vehicles entering and leaving the parking lot. Meanwhile, deue, the industry's first terminal intelligent ecosystem centered on car owners, can effectively improve car owners' parking experience.
