License Plate Number Recognition System
[System Introduction]
License plate recognition, also known as license plate recognition or vehicle license plate recognition, is an application of computer video image recognition technology in vehicle license plate recognition, which extracts and recognizes license plate numbers from image information. Vehicle number recognition is an important technology in the Smart Transportation System, which can be widely applied to various types of vehicles with unique numbers, such as cars, trains, non locomotives, etc.
The High Clear License Plate Recognition System is an application of computer video image recognition technology in vehicle license plate recognition, which extracts and recognizes the will license plate number from the image information.
The license plate recognition one body camera is specifically designed for the parking lot industry, and has launched an embedded Smart high-definition license plate recognition one body machine product, which exclusively integrates license plate recognition, camera, front-end storage, supplementary lighting and other one body functions. It uses high-definition and wide Updating CMOS and TI DAP. The peak calculation can achieve a high force of 6.4 GHz. Based on the Automatic Exposure Control algorithm for license plates, it has excellent performance, many functions, high adaptability, and strong stability, making it the best application form for license plate recognition in the parking lot management system.
The principle of license plate number recognition is as follows: divided into four major modules: image acquisition, license plate positioning, character minute cutting, and character recognition. Furthermore, software programming is used to achieve every minute of each part, and the license plate number is recognized at the back, outputting relevant information such as the license plate number.

Including: |
Identification host module (integrated with license plate recognition, camera, front-end storage, supplementary lighting, etc.) |
Equipped with a recognition host and a one body camera, it integrates license plate recognition, camera, front-end storage, and fill in lighting. It also features a high-definition CMOS and TI DSP, with a peak computing power of up to 1GHz. Based on the Automatic Exposure Control algorithm for license plates;
1. Uses 2,000,000-pixel high definition real-time video stream recognition, maximizing recognition rate, solving the problem of ground pressure sensation and car no recognition method;
2. Extremely optimized embedded license plate recognition algorithm: comprehensive recognition rate is high at 99.8%;
3. Large angle recognition, meeting ≤ 40 ° channel environment;
4. Excellent imaging Automatic Control: Automatic tracking of light changes, has an effect to suppress forward and backward lighting; Suppress car large lights at night;
5. Adaptive speed: 0-150 km/s mall
6. Offline charging, voice broadcasting, and display are available.
If the wide width of a single lane is larger than 4m, an additional license plate recognition host is required, most of which can be connected to 4 units |
