Why are number plates blurred even on stationary vehicles?
Answered by ANPR AI·Sourced
Short answer
Check focus before changing OCR settings.
Explanation
The capture distance may differ from the distance used when focusing.
Things to check
- Original-resolution plate image
- Lens focus
- Capture point
What to do
Refocus on the plate at the intended reading distance, then verify a passing vehicle in paused footage. Separate focus blur from motion blur.
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
