The Relevance of the License Plate Recognition System
Image Processing:
It is a machine learning (Artificial Intelligence) phenomenon through which a machine (computer) can process by appropriating digital images as an input, transform it into a binary unit, process it and produce output as a digital image. In the case of humans, face recognition is done through biometric identity captured by an electronic device.
License Plate Recognition System:
It is a technology that applies optical character recognition on an image to interpret the licence plate to generate the database by using the CCTV cameras located in the premises or road or through any means. Licence Plate Recognition System applies to store image captures along with the text mentioned in the license plate.
It is a design to automatically identify, recognize and distinguish vehicle details. It comprises low-level image processing techniques and higher-level artificial intelligence techniques. Through digital image taken by either a colour or a grayscale digital camera, as well as an infrared camera in progression to classify the vehicles using their number plate or license plate through optical character.
Optical character recognition is used to detect or recognize the characters in the licence plate by translating the pixel into numerical readable characters. Afterwards, the acquired data is employed to match with the database for acknowledging the complete detailing of a particular vehicle and its owner.
The methodology like how License Plate Recognition using Image Processing is work at ground level can be demarcated into four major steps-
Firstly, Captures vehicle number plate image, in second step Image pre-processing and filtering took place after that in third step Segmentation of the number plate image is done to get individual character and eventually in the fourth step Recognize the numbers plate image by using OCR algorithm.
The relevance of Vehicle Number Plate Recognition-
● Road Safety measures- This system is prominently relevant to detect the license plate which is not following the traffic norms or try to escape from the accidental area after doing an accident. To monitor those who violate traffic protocols is one of the biggest problems facing nowadays.
● Detection of Criminal activities- It aid to track the vehicle which does not follow the traffic norms, keep on eye on anyone who is doing rush driving which led to an accident. Along with if any illegal or unethical activity is being conducted inside the vehicle including stolen of the vehicle can also be curtailed by using this method.
● Safety and Surveillance - For safety control measures on highly restricted and protected areas like a military zone, Parliament and its periphery, Supreme Court and high courts along with governmental buildings and offices. It also protects from forcefully capturing vehicles for illegal and brutal activities.
In the automation and digital world, License Plate Recognition System using Image Processing is the need of the hour as it not only serves to recognize or detect the vehicle but also assists to maintain a robust database for transportation management and relevant services.
