Why does ANPR fail on crossing traffic but work on cars approaching the camera?

Answered by ANPR AI·Sourced

Short answer

Sideways image motion produces more blur.

Explanation

The required exposure depends on vehicle speed and the angle to its path.

Things to check

  • Direction of travel
  • Exposure time
  • Sharpness in paused moving frames

What to do

Shorten the maximum exposure and adjust illumination. Validate with moving vehicles at the intended speed rather than a parked car.

ANPR Edge

Skip the dedicated ANPR camera. Read plates from the cameras you already have.

ANPR Edge is plate-recognition software that runs on a PC at your site and works with ordinary IP cameras, so plate reads no longer depend on one vendor's camera, NVR or firmware.

  • Works with standard IP cameras over RTSP
  • One license per location covers every camera
  • Runs on a Windows PC or Mac you own
