What LED wavelengths are needed for LPR license plate recognition?

In LPR (License Plate Recognition) systems, the selection of appropriate LED wavelengths is crucial for achieving high recognition rates. Typically, the following LED wavelengths are used:

LED Wavelengths Used in LPR

White Light LEDs: For providing uniform and bright lighting, covering most of the visible light spectrum (400-700nm).

Infrared LEDs: Invisible to the human eye, useful for low-light environments and enhancing reflections on license plates (around 850nm).

Ultraviolet LEDs: Emit ultraviolet light to make fluorescent materials on license plates glow, improving contrast and clarity (around 365nm).

 

Factors to Consider When Selecting LED Light Sources

Light Intensity: Adjusted according to the application scenario to ensure clear images.

Color Temperature: Affects the color of the license plate images; chosen based on the actual situation.

Lifespan and Stability: Important for the long-term stable operation of the LPR system.

By carefully selecting the appropriate LED wavelengths and light source types, LPR systems can significantly improve the accuracy and reliability of license plate recognition.
