The conflict between recognition speed and large pixels
The farther the license plate is for the license plate recognition camera, the smaller the pixels are, the larger the pixels are the closer they are. The parking lot has shorter lanes than other scenes, and the recognition of the current license plate recognition system is real-time. To ensure the recognition speed, it supports the identification of large-pixel-width license plates, which is a typical contradiction. Usually the license plate pixel width is too large, the recognition speed must be slow, recognition speed is faster, it requires the license plate pixel width within a certain range.
Use existing conditions to make the algorithm efficient
Parking lanes usually have two lanes. In order to better identify the effect, a deceleration belt is usually installed at the entrance and exit of the parking lot to ensure that the pictures captured by the license plate recognition camera are clearer. Therefore, it is possible to maximize the use of conditions such as slow speed, good lighting, low interference conditions, and generally only one car at a time, so that the algorithm can reach a perfect state under such conditions.
Multi-technology to achieve a good parking entrance "vehicle match rate"
The license plate recognition system's own architecture and internal recognition algorithms are also constantly improving and improving. Particularly worthy of attention is that some technologies developed based on the license plate recognition hardware platform, such as video speed measurement, vehicle identification, vehicle local feature identification and comparison, etc., cooperate with license plate recognition in order to achieve good parking entrances and exits. "This is only the characteristics of the parking lot environment.
White list function
A major feature of residential car parks is that the vehicles entering and leaving the car every day are basically fixed, so the white list function of the license plate recognition system can be used for this part of the car. After the white list is imported into the license plate recognition system, the vehicles in the white list function list can be automatically released. Blacklists can also be added to vehicles that you do not want to put.
Laser cleaning equipment is a new generation of surface cleaning high-tech products. It is very easy to install, manipulate and achieve automate. Easy operation, you only turn on the power and open the device, machine will be cleaned with no chemical reagents, no media, no dust and no water. With the advantage of manual adjustment of the focus, fit curved surface cleaning, good surface cleanliness and so on . Laser Cleaning Machine can clean the resin of subject surface, oil stains, stains, dirt, rust, coating, coating, paint.
Advantage of Laser cleaning
1. Compact construction,Gentle and Precise cleaning
2. Ultra-high stability
3. Lower the cost of operation
4. Maintenance free
5. No damage to substrates
6. Green process
7. Highly reliable
8. Portable and precise
With those advantage. It can be applied on Oxides/rust removal from metallic surface;Cleaning rubber molds; Pre-treatment for coating; Removal of oil and grease,etc.; Paint removal and De-coating; Pre-treatment for brazing and welding; Restoration and conservation etc.
