License plate recognition (LPR) camera series
The process of camera recognizing license plates includes the following steps:
Detect license plates in images or videos recorded by cameras:
When a vehicle passes through the vision of the license plate recognition camera, it will detect and determine the location of the license plate in the recorded image or video.
Recognize characters in license plates:
After determining the location of the license plate, the license plate camera will use character recognition algorithms to extract the characters on the license plate. Character recognition algorithms can be based on techniques such as pattern matching, feature-based recognition, or deep learning models such as Convolutional Neural Networks ( CNN).
Processing and comparison:
After extracting the characters, the LPR Camera will process and compare with the previously stored database to accurately identify what the license plate is. This database can be a list of pre-input license plates or license plate laws of the locality where the camera is equipped. The license plate recognition result will be returned as a sequence of license plate characters of the recognized vehicle. However, the accuracy of a license plate recognition camera can depend on many factors such as image quality, environmental conditions (light, humidity, etc.), the newness of the license plate, and other factors. another factor.
Special features of the AI camera line recognize license plates
Features of the camera line to recognize license plate numbers
Some features of the camera line that recognizes license plates based on the information provided are:
- Collect license plate data in real time: Detect license plates and automatically take a photo of the license plate when any vehicle passes through the camera’s operating range.
- The speed of number plate recognition is very high, allowing accurate recognition of number plates of fast moving vehicles on the road, including on highways.
- License plate recognition cameras also recognize vehicle make, vehicle type and color, helping to classify and identify vehicles on the road.
- Supports searching and exporting a list of captured license plates, serving the management of license plate data collected over a certain period of time.
- In areas such as streets, checkpoints, highways and other traffic locations, license plate recognition cameras actively support traffic monitoring, management and ensuring traffic safety and security.
In addition, some license plate recognition cameras also have special features such as:
- Measure vehicle speed, help evaluate the actual speed of vehicles on the road, and assist in checking and handling speed-related violations.
- Statistics on traffic data including traffic flow, traffic density, speed, help provide analytical data and evaluate the effectiveness of the road traffic system.
- Detect violations such as driving in the wrong lane, driving illegally changing lanes, driving without wearing a seat belt, using a phone while driving, helping to detect, monitor and manage to minimize these behaviors violate
Practical application of license plate recognition camera
License plate reading technology is a popular technology used in license plate recognition cameras, allowing automatic identification and recording of license plate information from images or videos. LPR technology is applied in many different fields, including:
- Traffic security: License plate cameras are used to monitor and manage traffic on the streets. LPR cameras can be installed at toll stations, public parking lots, entrance/exit gates of urban areas, industrial parks or ports to automatically record vehicle license plates and check vehicle identity. vehicle validity, supports automatic toll collection, monitors compliance with traffic laws, or detects and warns of violating vehicles.
- Privacy and security: Specialized cameras capturing vehicle license plates are used in security systems, helping to identify and register information of vehicles moving into protected areas such as military areas and ports. sea, airport, industrial park, or other important areas. LPR technology can also be combined with video surveillance systems to alert and detect suspicious activities or violations.
- Parking lot management: License plate recognition cameras are used in parking lots to read license plates and automatically identify entering/exiting vehicles, supporting automatic toll collection and management, helping to increase efficiency and Synchronization in parking lot management.
- Traffic flow management: LPR technology is also used to analyze and measure traffic flow, helping to improve urban planning and traffic flow management, detect traffic jams, calculate journey times, or make predictions about future traffic conditions.
- Crime prevention: LPR technology is also used in crime prevention activities
