AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively identify and prevent fraudulent activities at parking lot entrances and exits, including counterfeit license plates and vehicles, leading to economic losses.

Method used

A method based on multi-frame license plate bounding box texture comparison is adopted. By combining a contour scanner, ground inductive loop and camera with a depth detector, multi-dimensional data is collected to identify the shape of the vehicle's front, metal signals and image features. The angle is dynamically adjusted to collect multi-frame images, and the local texture distribution is analyzed to identify counterfeit license plates.

Benefits of technology

It significantly improves the ability to detect counterfeit license plates and fake vehicles, reduces the false alarm rate, ensures normal passage, and enhances the security level of parking lot entrances and exits.
