Hello everyone! In today's daily life, license plate recognition software, which is what we usually call LPR (Plate), occurs very frequently in parking lot management and traffic violation handling. Many friends have various confusions about what this thing is and how to choose. Today, I will talk to you about the practical and practical things about this LPR software, hoping to help those in need.
Simply put, LPR software is a computer program that can automatically identify the license plate number by the vehicle picture taken through the camera, right? Its workflow is roughly divided into several steps: first, you have to use a camera to take a picture, and then process the captured pictures, such as adjusting the brightness of the picture and removing noise from the picture. After that, you can find the position of the license plate from the picture, then divide the characters on the license plate, and finally use a special recognition algorithm to turn the characters into text numbers… The whole process seems quite simple, but in fact the technology involved is quite complicated. Of course, if you have the need to purchase weak current intelligent products, you can provide global procurement services for weak current intelligent products!
Next are several key modules to focus on when choosing LPR software. These modules will affect the best use of the software:
1. Identification accuracy: This is definitely what everyone cares about the most, right? A good software can have an accuracy rate of more than 99% when the environment is good. Even if the light is not good and the license plate is a little blurred, it can still have about 95%. If the accuracy rate is too low, it will be too difficult to use.
2. Processing speed: It is the time it takes for the software to take pictures to recognize the results. Generally speaking, it must be within 1 second. If the processing speed is slow, it will easily cause congestion when there are too many cars, which will be troublesome.
3. Compatibility: The software must be compatible with most cameras and computer systems, otherwise it will be useless if you buy it and cannot install it or use it.
4. Functional expansion: Can you add some functions according to your needs, such as counting daily traffic, binding vehicle entry and exit records, etc., software with good function expansion is more flexible to use.
Here are some common questions to solve your doubts:
Q: Do LPR software have any special requirements for cameras?
Answer: Generally speaking, high-definition cameras are required, with pixels at least 720P or above, preferably 1080P. Moreover, the angle and height of the camera are also given due to the angle and height. Too much angle and inappropriate height may affect the recognition effect… So you have to choose the right one when buying a camera.
Q: Can LPR software accurately identify it at night or rainy days?
Answer: Good software will have functions such as infrared fill light and low light noise reduction, which can be recognized at night. However, if the rain is too heavy and the rain blocks the license plate, it will not work. However, the recognition rate of normal rainy weather can still be guaranteed to be above 90%.
Another comparison is, what is the difference between some cheap LPR software and more expensive software? Cheap software may have low recognition accuracy, few functions, and after-sales service, and problems will arise when used. Although expensive software is expensive, it has good performance in all aspects, which is worry-free to use, and after-sales service is also guaranteed… So when buying, you can't just look at the cheap price.
When using LPR software, there are some tips to remember: clean the camera on schedule and don’t let dust block the lens; check whether the software is updated frequently, and the performance may be better after the update; if you find that the recognition accuracy decreases, adjust the position or parameters of the camera in time… Do these well, the software will be much smoother to use. I personally think that when choosing LPR software, you still have to consider your actual needs and budget, compare more products, and choose a brand with a good reputation and mature technology. Although this may cost more money, it is safe and worry-free to use.
