Advanced Vehicle Checkpoint System

The checkpoint camera system captures vehicle information like license plates, vehicle type, color, and speed violations. It uses a 3MP camera mounted on the roadside to capture images of passing vehicles. The system architecture includes front-end subsystems that capture images and a back-end control center subsystem that analyzes and stores the data. Deep learning algorithms help the system accurately recognize license plates and vehicle features at rates over 98% and 90%, respectively.

Checkpoint System

The checkpoint camera is mounted on the road, when a vehicle passing through,
information such as license plate, vehicle type, vehicle color, violation behaviors
and speed will overlay on capture image.

Highlights
Innovative GMOS sensor with better capture image quality than traditional ANPR camera.
Due to the inherent of CCD chip, smear effect has always been a big problem of the image, the new
generation of capture camera based on GMOS sensor, can completely eliminate the smear effect.
