What Is a License Plate Recognition System and What Is Its Principle- TigerWong

Tigerwong technology license plate recognition system is more and more popular. At present, it has been widely used in business parking lots, hotel parking lots, community parking lots, etc. License plate recognition can not only easily achieve one card and one vehicle, improve vehicle security and management level, but also make the parking lot look more modern and higher level. It is one of the necessary configurations of high-end parking lot system that attaches importance to user experience. So what is the license plate recognition system and what is its principle? In short, the license plate recognition system collects the license plate image of the vehicle through the camera at the entrance and exit. After processing, the image information is transformed into a digital signal, and then the license plate number is recognized and output. License plate recognition system is mainly composed of vehicle detection, image acquisition and license plate recognition. Its hardware equipment includes detector (detecting whether the vehicle enters the recognition range), camera equipment, lighting equipment, image acquisition equipment, processor (computer) for recognizing license plate number, etc. its software mainly includes some algorithms, such as license plate location algorithm License plate character segmentation algorithm and optical character recognition algorithm. Let's explain them one by one. 1 Vehicle detection vehicle detection can be said to be the trigger of license plate recognition system, which is mainly used to detect whether the vehicle needs to be identified. The commonly used detection technologies include ground induction coil detection, infrared detection, radar detection, video detection, etc. 2 When the image acquisition detector detects a vehicle, the import and export cameras will collect the vehicle license plate. The equipment composed of this part includes camera equipment, light filling equipment, etc. The license plate recognition rate is closely related to the clarity and quality of the image, so we need to use better cameras and meet the lighting conditions in this part. 3 License plate recognition license plate recognition needs to recognize the license plate number and color, and the algorithms between them are different. The steps of license plate number recognition are as follows: 1. To locate the license plate area, the first thing to do is to locate the vehicle license plate position and set the acquisition area; 2. Segment the characters in the collected picture to segment the characters; 3. Recognize the segmented characters to form a number. License plate recognition has other algorithms and steps for color recognition, which we won't explain here. We just need to know that number recognition and color recognition complement each other. Let's briefly introduce the principle of license plate recognition system. I hope you can have a general understanding.
