What is the core feature of the license plate recognition camera?

The license plate recognition camera converts optical image signals into electrical signals for storage or transmission. The license plate recognition camera has added the license plate recognition function. The light reflected on the license plate is collected by the camera lens so that it is focused on the light-receiving surface of the camera device (for example, the target surface of the camera tube), and the light is converted into electrical energy through the camera device. The "video signal", and then through the license plate recognition algorithm analysis, to obtain a corresponding license plate number of a process.

Core features

Embedded license plate recognition algorithm: The integrated recognition rate is higher than 99.58%;

Excellent imaging automatic control: automatic tracking of light changes, effective suppression of light and backlight; night suppression of car headlights; fill light based on image analysis algorithms to control, to avoid the traditional light-resistor based on light instability;

Offline operation: Pre-data storage function;

No license plate vehicle intelligent processing: multi-trigger mechanism guarantees normal traffic management of vehicles without license plates (or severe fouling, etc.).

Wide dynamic CMOS used by license plate recognition camera, local exposure based on license plate, and photo compensation technology controlled by image algorithm are completely different from ordinary license plate recognition cameras. It can automatically track light changes and effectively suppress the light and backlight, especially at night. Suppress the interference of car headlights, thus clearly capturing the license plate. In particular, light compensation based on image algorithm control avoids the instability of the traditional photo-resistor fill light, and thus ensures a good imaging effect in night, backlight, headlight direct, bad weather and other environments.
