How LPR Technology Implemented in Industries
Thanks to the advancement of computer vision technology, especially in the LPR field, the technology has brought many benefits to various industries.
License Plate Recognition (LPR) is not really new technology. LPR was developed by the British Police Scientific Development Branch in the UK to fix locations like toll bridges and parking lots. At that time, LPR technology only had below 60% of accuracy. However, many people saw it as a phenomenon during that time.
Within a few years, there were a lot of improvements made, mostly on the accuracy, and it was used at various locations around the UK. Nevertheless, LPR was not widely used at that time as the cost of the production was very costly. The new developments in cheaper and easier to use software were started to be implemented during the 1990s.
LPR works through capturing photographic video or images of vehicle license plates, and then it will be processed by a video analytics engine that is able to convert images into a text entry. Although the accuracy has far better improved compared to the early stage of the development, there are still many factors that affect the accuracy of the reading, like camera angle, object distance, lighting, and vehicle speed.
Thanks to the advancement of computer vision technology, especially in the LPR field, the technology has brought many benefits to people in various fields or industries. Combined with IoT technology, LPR also gives people valuable insight on the traffic, based on the data it gathered.
LPR has been commonly used by parking management companies. Most of the companies abroad have implemented LPR for its automatic parking ticket. The parking ticket is generated automatically by reading the customers’ vehicles license plate when they enter and leave the parking area. The timestamp will be generated automatically when the camera captures the license plate.
LPR can also be used in a warehouse, allowing company management to track how many trucks or vehicles are in and out the warehouse area. It can also be used to track how long it takes for a single truck to deliver goods from one location to another. For security and safety reasons, LPR can also create vehicle blacklist and whitelist for the area.
Through the first use, LPR is commonly used for solving various criminal cases in England. It helped the police to arrest fugitives, find a stolen car, or reveal a murder. Nowadays, LPR also helps police to enforce traffic regulations. The camera will capture the license plate of traffic violators, and the police can send the electronic fine to the violators. It will help the police to maximize the efficiency of onground manpower allocation.
Today, several property developers also implement LPR for its high-end clusters. Installed on the cluster gates, it allows the residents to go in and out of the clusters automatically without having to ask security officers to open or close the gate. In addition, it will also record all the vehicle license plates, which is useful if something unwanted happens.
For further implementation, LPR can be also used for electronic toll collection. The camera will capture the license plate of the vehicles when they enter the gate, and capture it again when they exit the toll road. Combined with automatic payment processing, it will benefit customers as it offers a fast and easy payment method, and saving time for stopping at the toll gate.
To make it more valuable, all the data captured will be sent through a dashboard. Imagine how the amount of data will provide insight to the authorities or building management. They will get insight on how many vehicles pass certain roads, how many times certain vehicles go in or out of certain area, or even how much time a vehicle needs to go from one location to another.
