Vehicle Recognition

Algorithm Introduction
For the frame selection results from structured detection and tracking in video streams and the captured images from intelligent front-end cameras, our solution employs AI vision algorithms to extract vehicle attributes and features. It supports multi-dimensional querying and analysis of various attributes including vehicle type, vehicle color, vehicle model, license plate number, and license plate type.

Urban Roads
At urban intersections and arterial roads, AI vision algorithms automatically monitor traffic violations such as red-light running, speeding, and illegal parking. By analyzing multi-dimensional vehicle attribute data, the system evaluates urban traffic flow and vehicle type distribution, providing data support for traffic planning and congestion management. -
Expressways
Deployed at expressway entrances/exits, service areas, and key road sections, the solution leverages vehicle attribute data to count traffic volume by time periods, optimizing road management strategies. Through license plate type recognition, it rapidly screens vehicles violating passage regulations, ensuring driving safety on expressways.
FAQ

Algorithm AccuracyAll algorithms published on the website claim accuracies above 90 %. However, real-world performance drops can occur for the following reasons:
(1) Poor imaging quality, such as
• Strong light, backlight, nighttime, rain, snow, or fog degrading image quality
• Low resolution, motion blur, lens contamination, compression artifacts, or sensor noise
• Targets being partially or fully occluded (common in object detection, tracking, and pose estimation)
(2) The website provides two broad classes of algorithms: general-purpose and long-tail (rare scenes, uncommon object categories, or insufficient training data). Long-tail algorithms typically exhibit weaker generalization.
(3) Accuracy is not guaranteed in boundary or extreme scenarios.
