License plate recognition for mobile radars
The idea would be to use the rear camera of the phone to check the licence plates of the cars, and make OCR to read it.
Then it will be compared to a database where users could report the licence plates of the mobile radars onboarded in cars.
Waze could then alert that there is an onboarded radar on the road, and also alert other users with a flag on the map.
If you mean you hang the phone on the windscreen with a clear view on the road ahead and you scan all license plates... not that easy too implement I think:
- getting license plates in focus + extra cpu cycles for OCR.
- world wide database of police plates, which police won't like that much
- different kind of plates in different countries.
