License plate reading and image processing; It is performed by detecting and separating the license plate region on the vehicle images obtained from the cameras and reading the characters on the plate using optical character recognition methods, also called image processing. Thanks to this software-based method, digital images are taken and plate reading is performed.

License plate reading and image processing technology; It captures license plate images and combines high-speed cameras and advanced software to convert them into data that can be compared with information in other databases. This method, which can be performed using mobile or fixed cameras, uses cameras small enough to be mounted on police cars, road signs or traffic lights, or placed on roadsides or bridges. In this way, a driver’s geographic location can be obtained along with the date and time a vehicle was found in a particular location.

License plate reading and image processing technology captures computer readable images of license plates. These high-tech devices allow law enforcement to compare license plate numbers with those of stolen cars or cars used by people suspected of involvement in criminal or terrorist activities. In the private sector, for example; It is also used to repossess vehicles in the event of default on payments, monitor parking or control access to private property, among other purposes.

License plate reading and image processing; It can be defined as the capacity to capture photographic video or images from license plates and convert optical data into digital information in real time. It aggregates license plate digital information along with other data such as vehicle direction and speed, allowing operators to instantly collect and correlate more data about each vehicle passing through a checkpoint.

When the camera used in this technology captures the license plate image, the camera firmware uses special OCR routines to convert that image into digital characters. Videos and photos of the plates are captured and processed by a series of algorithms that transform the images step-by-step into text information. It is determined which side of the vehicle image is the license plate. The angle of the plate images is adjusted and calculated at the optimum size. The contrast and brightness of the captured license plate image are adjusted. There are individual alphanumeric characters on the plate. The captured image is converted to alphanumeric text input. Text information is validated with a specific set of rules. With the character separation process, the characters are removed from the image and optical character recognition is performed. Country-specific syntax and geometric checks are performed. All these processes are performed simultaneously and in real time. This significantly speeds up the video analysis process on cameras. In addition, the interior of the vehicles is blurred to protect the personal image rights of those inside the vehicle. The resulting text information can then be compared with databases to, for example, identify vehicle owners or detect stolen vehicles.

license plate recognition system; Used on highways and controlled crossing points. On highways;
Ensuring city security by keeping the entrances and exits of the city under control,
Tracking and controlling stolen or suspicious vehicles,
Measuring vehicle density on highways,
Realization of traffic regulations,
At controlled crossing points;
Reducing entry, exit and waiting times,
Preventing the formation of traffic jams,
It can be used to ensure security during entry and exit.

License plate reading system; It can recognize the license plate of vehicles traveling at 250 km/h. This system, which has a 98% recognition rate, has full compatibility with KGYS (MOBESE) projects. Optionally, it has the feature of recognizing the brands and colors of the vehicles. In addition to the vehicle speed detection feature, it can operate in different light conditions during the day and night. Registered license plates can be queried and officially reported.
