Car Plate Recognition

Patent: MS-LPR004
Car plate recognition can be used in parking lot management, weighbridge, parking space guidance and reverse car search management, etc. Relying on advanced vision algorithms, MS-LPR003 offers an incredible 99.7% recognition rate for over 100 countries.

Car Plate Recognition:

Car plate recognition, also called license plate recogniton or number plate recognition, it is a technology that uses artificial intelligence and deep learning algorithms to automatically detect and recognize the characters of vehicle license plates.

Car Plate Recognition is a valuable tool in many industries. It is used to identify and track vehicles by capturing their license plate numbers through digital imaging technology.  LPRs are widely used for law enforcement, security, fleet management, road access control and tolling applications.

What affects the accuracy of car plate recognition?

Affecting the accuracy of license plate identification includes both internal and external factors.There are two internal factors:

1. Recognition method

There are two different recognition methods in the license plate recognition system, soft recognition and hard recognition. Soft recognition is the algorithm of license plate recognition on computer software, also called background recognition. Hard recognition is an algorithm on the front-end camera, also called front-end recognition.

2. Camera resolution

The higher the resolution of a captured image, the better chances of obtaining accurate recognition results. Low-resolution images can lead to the misreading of license plates and thus inaccurate recognition rate.

There are many external factors that affect the accuracy of license plate recognition, mainly as follows:

1. Illumination:

strong light, low light, backlight, thunderstorm weather and other factors will also affect the license plate recognition rate. Adding fill light can solve this problem.

2. Camera angle

  It is important that the camera capturing the license plate be positioned at an appropriate angle for good accuracy. If not, skewed images or unrecognizable license numbers could cause a decrease in recognition rate.

3. Vehicle speed

The camera for license plate recognition will select one of the continuously played pictures as the output picture. Then select different frame numbers as recognition pictures. If the speed of the car is too fast, it is easy to drop the frame, and it will not be recognized. It is recommended to add a speed bump before the barrier.

4. License plate

No matter how advanced the license plate recognition algorithm is, it is impossible to correctly identify license plates with occlusions or large stains. Keeping the license plate clean and unobstructed is the first step to ensure correct recognition.
