What Should You Know About An Automatic Number Plate Recognition System?

You have probably heard about smart cities, intelligent transportation systems, and smart vehicles. These are technological advancements that have facilitated our life. With technical advancements, we have an increased risk of safety and security whether we are at our home, in markets, at workplaces, etc. To counter the threats, technology has gifted ANPR. keep reading the post to know more about it, its usage, work process, benefits, and so on. 

What is automatic number plate recognition (ANPR)?   

In simple words, automatic number plate recognition is a technique, which enables a concerned authority to read the number attached to a vehicle. You can come across ANPR with several different names that are as follows:

• Automatic Licence Plate Recognition (ALPR)
• Automatic Vehicle Identification (AVI)
• License Plate Recognition (LPR) and
• Car Plate Recognition (CPR)  

Work process of ANPR  

To detect a vehicle, an automatic number plate recognition system applies a particular pattern and algorithm technology. You can divide the entire work process of this system into 4 steps that are as follows:

• Clicking the image of a vehicle – With the use of surveillance cameras, it captures the image of a vehicle. The image is crucial for later stages.    

• Detection of the number plate – There is an application of algorithms to find the license plates in the captured vehicle image. After that, the ANPR system turns the clicked images into grey-scale images and removes noise from there.  

• Segmentation of characters – Character segmentation leads to having the right outputs. Proper segmentation is crucial. And so, algorithms rely on the use of neural networks. And the segmentation takes place in two ways – horizontal segmentation and vertical segmentation. The use of the ways has an association with the placement of numbers on the vehicle plate. 
• Recognition of the segmented characters – It is the last step of detecting and recognizing a vehicle number plate. The recognition process is extraction in which the system converts data and makes it readable for computers. Further, the data is matched with the database for recognition and identification.

• Live preview of back and front or all sides 

Where can you install and use ANPR systems? 

Automatic number plate recognition systems find their applications in several areas. Here are some of them where you can use them:

• Parking management 
• Toll plazas
• Bus lane management 
• City surveillance 
• Sports venues
• Border control 
• Law enforcement 
• Traffic management 

Benefits of using automatic number plate recognition systems 

Using ANPR systems is highly beneficial for authorities and businesses. Here are some valuable advantages that you will have:

• Automation – Its installation paves the way for automating the tracking, recognition, and identification of vehicles for a respective purpose.   

• Analytics – You can use the data for analyzing traffic flow and managing the same well. For this, you can integrate with the ITS (intelligent transportation system).   

• Identification – Fast recognition paves the way for fast identification of vehicles on the stored or available information.   

• Efficiency  – It is an ideal solution for accurate and fast recognition of a vehicle’s plate number if you don’t rely on manual methods. 
• Convenience – It produces a hassle-free and seamless experience for end-users. With it, you can improve your customer experience in parking management and retail store operation.  

Conclusion 

An ANPR system is today’s need. Before having this, you should know what ANPR is, its need, applications, work process, etc. By having sound familiarity with it, you can get a good automatic number plate recognition place for your residential/commercial parking and traffic management.
