Hello Guise,

Anybody here know how to make your own LPR system using only software + an IP Camera?

Or otherwise does anyone know what is the most affordable ANPR system you can buy?

Regards,

Give us more info pls...

Why are you asking? Is it for personal/commercial use?
 
you'll get a better set of responses if you posted it into the Software sub-forum.
Try to be specific with your requirements so the community can help you more succinctly.

ANPR isn't such a difficult to google subject. I don't see the need to give a big explanation.
Basically we are looking for an affordable entry level system with 4 cameras

2 incoming 1 visitors & staff and 1 transport vehicles
2 leaving 1 visitors & staff 1 transport vehicles

Visitors and staff will be moving while transport vehicles will have to sit on the weighing bridge so perhaps it wouldn't require such an expensive camera as for the fast moving visitor entry point.
 
Find out what they use at ORTIA, that system logs your numberplate relatively quickly, I've noticed.

Easy...

Simple segmentation (morphological segmentation would work well) and thresholding, followed by simple scanning of columns (to separate characters), followed by simple recognition (local binary patterns would be a good choice).

All of the above (aside from the local binary patterns) is easily implemented using OpenCV. Once you have the basic system, optimisation is a fairly straightforward task. And there are a number of research papers freely available that discuss different classifiers that yield better results in specific situations.

are you a wizard?

+1 haha not so simply said and not so simply done


Visec surveillance software does license plate regoniction, so does the Geovision software that comes with there cameras.. not sure how easy it is to implement the info into a separate system though!
 
For the wizards:

You can always use Halcon.

Or Labview with the machine vision module add-on.

Not cheap and/or easy.
 
as mentioned previously Visec and Geovision have options. Dont go for the cheapest when shopping around, LPR is not simple! When you have found software/hardware inquire about SOUTH AFRICAN reference sites. When LPR first started hitting our shores alot of system had hassles with certain SA plates like the eastern cape. Visec & Geovision have since addressed this. Another good option to look at is i-cube

Dont get to hung up on using IP cams. To get quality reliable images from IP you will need to go with the very high end expensive stuff. Analog gives your features like WDR and HLC on budget.

Most system will give your reading information on a separate DB so you can extract and integrate with other systems. Geovision already offers alot of features inside there software

If you have more queries just ask, I have done LPR projects.

Yeah, we develop in Labview and have the vision add-on that can do OCR etc. So we could do a custom solution, its pretty doable.
However, development is not cheap which I'm assuming is a big thing for the OP. I'm sure that a turn-key solution is out already out there which would work out much cheaper...provided the features would suffice.

+100 great advise! Although IP is 'cooler' Analog is more reliable and cheaper.

Had 1 project where the client insisted on IP cameras but didn't want to pay the premium for it. So they ended up with a not very reliable system and ended up paying double in the end to get better quality equipment (I got to say I told you so and markup on two sets of equipment :D)
 
Hi,

I work for a Research and Development company, we recently developed an ANPR software package, our system is affordable and flexible...

A few things that we've come across:
1. IP cameras generally don't work too well, unless you go for high end ones which are expensive.
2. Analog cameras work great if they are 1/4' CCD, auto focus with optical zoom, and you can get very good ones for less than R2k, using a USB dvr card that you can get for R300

If you are still interested, contact me and I can give you more details.

So you're asking for help but those who help you should do their own research first?
Why didn't you just google it in the first place then?

When asking for help the least you can do is give a rundown of why you need the help.
 
Doesn't OpenCV have the tools that you may need?

Its a Computer Vision library for those who dont know (OpenSource BSD) Ive used it a couple of times.
 
LPR Software

Hi,

You can contact me in regards with LPR Software.
We use Visec with a 100% success rate,in bussiness parks,public roads and for different neighborhood watches in and around the Western Cape.
