The license plate recognition machine can indeed capture clearly in rainy and snowy weather, thanks to its built-in multiple anti-interference black technologies.1. Waterproof designWaterproof cover: Some advanced license plate recognition systems will install waterproof covers on the camera, such as the waterproof cover made of transparent acrylic board used by Shengxin Toll Center of Zhejiang Transportation Group. This design can effectively block the invasion of rain on the camera lens and maintain the clarity of the lens.Waterproof material: The housing of the license plate recognition camera is usually made of waterproof material to ensure that the internal electronic components are not affected by the humid environment, thereby maintaining stable performance.2. Image enhancement technologyWDR technology: WDR (wide dynamic range) technology allows the camera to see image features under very strong contrast. In rainy and snowy weather, due to light reflection and scattering, the license plate recognition camera may face the problem of excessive light and dark contrast. The WDR technology can solve this problem and ensure that the camera can capture a clear license plate image.Glare shielding: Glare shielding technology is based on low-light color cameras, and shields the brightest part of the image through strong light shielding. This is mainly to block the strong light of the headlights or interference from other light sources during vehicle driving, so as to effectively capture the license plate.3. Adaptive adjustment technologyAdjustable shutter: License plate recognition cameras are usually equipped with an adjustable shutter function to adapt to shooting needs under different light conditions. In rainy and snowy weather, due to changes in light conditions, the camera can automatically or manually adjust the shutter speed to ensure that a clear license plate image is captured.Automatic fill light: Some license plate recognition systems are equipped with automatic fill light devices, such as LED fill lights. In low light or bad weather conditions, these fill light devices will automatically light up to provide enough light for the license plate to ensure that the camera can capture a clear license plate image.4. Intelligent algorithm optimizationLicense plate positioning algorithm: License plate recognition systems usually use advanced license plate positioning algorithms that can quickly and accurately find the location of the license plate in complex images. This helps ensure that the system can accurately capture the license plate image even in rainy and snowy weather.Character recognition algorithm: The license plate recognition system also uses high-precision character recognition algorithms, which can accurately analyze and identify the captured license plate images. These algorithms can cope with various complex situations, such as license plate damage, blurred characters, etc., to ensure the accuracy of recognition.In summary, the license plate recognition machine achieves clear capture in rainy and snowy weather through a variety of black technology means such as waterproof design, image enhancement technology, adaptive adjustment technology and intelligent algorithm optimization. These technologies not only improve the accuracy of license plate recognition, but also enhance the stability and reliability of the system.
