Automatic Number Plate Recognition for Digital Signage

Here’s the lowdown on the digital billboard campaign I delivered in 2009 that recognised the make/model of a passing car and then displayed an advert tailored to that car. Here’s a link to a video of the advert in action

The prototype code that was used to prove that the ‘Castrol Oilcam’ project would work is detailed below.

The ANPR (Automatic NumberPlate Recognition) camera output has been replaced with a text file called latest.lpr. Put a UK car number plate in this text file, in the same folder as the flash movie and the flash movie will read it.

The most progress I made in this version was realizing I can send an html request/query from Flash and then ingest/interrogate the resulting html page source code from the host web server.

If you haven’t done so before, please read the site disclaimer before downloading and/or commenting.
