Hi Everyone,
Can anyone please suggest me some cameras (or companies) which are good for licence plate recognition. I know axis communication is one of the best in this field but the cameras are really expensive and I cant afford it.
I would love to know more companies or specific camera models if anyone has in there mind.
Cheers!

You need to be specific: At what speed you want to do license plate recognition? If it is slow, then perhaps give Hikvision (i.e. DS-2CD2T12-i3) a try.

Thanks a lot for your prompt response.
I am looking to do number plate recognition for slow moving vehicles. Speed of the vehicle will not be more than 30-40km/hr (15-25 miles/hr).
Thanks for your suggestion. I will look into it.

Great question, I would also love to hear an answer on this question. I myself am looking for good cameras for doing license plates at speed 70mph.
I am currently using a Rapier 30 which is a nice compact camera for mobile use, like on a squad car. I am fairly happy with it. It has an overview camera, and an LPR camera, and both have a variable focus adjustable lense on them. It is great at night, and does a good job. The only weird thing I have had is that it is a PAL camera, and so anything at speed I have had to do deinterlacing in my directshow capture. Other than that, I like the camera. The other camera I used was an I-Sharp camera, much smaller to mount, it does a good job also. It does not have the adjustable lense, it comes in fixed, so you have to choose. It was lots fancier, zillions of settings, makes it harder to learn, but it could do a lot that way. For example it had a setting where you could have it shoot with 3 different IR settings, and just pick your frames. Not a bad camera, I plan on playing with that one again. It was real good at being in constant focus.
I would really be interested if anyone has experience with other mobile lpr cameras for vehicles.

Hello Mr. Mikael,
So, after a lot of thinking, I finally decided to get hikvision DS-2CD2632-I. Although I have managed to setup the camera and everything is working cool but I am still struggling to have a live stream with LINUX and opencv module. Here is my code and the error. Could you help me out with it.
Code
int main()
{
VideoCapture cap("http://192.168.1.64:8000/videostream.mjpeg?user=admin&pwd=qazxc1234&resolution=32");
if (!cap.isOpened()) // if not success, exit program
{
cout << "Cannot open the video cam" << endl;
return -1;
}
else
{
cout << "Device Opened" << endl;
}
double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); //get the width of frames of the video
double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); //get the height of frames of the video
cout << "Frame size : " << dWidth << " x " << dHeight << endl;
namedWindow("MyVideo",CV_WINDOW_AUTOSIZE); //create a window called "MyVideo"
while (1)
{
Mat frame;
bool bSuccess = cap.read(frame); // read a new frame from video
if (!bSuccess) //if not success, break loop
{
cout << "Cannot read a frame from video stream" << endl;
break;
}
imshow("MyVideo", frame); //show the frame in "MyVideo" window
if (waitKey(30) == 27) //wait for 'esc' key press for 30ms. If 'esc' key is pressed, break loop
{
cout << "esc key is pressed by user" << endl;
break;
}
}
return 0;
}
Error
GStreamer Plugin: Embedded video playback halted; module source reported: Connection terminated unexpectedly

Thanks in advance

The camera I/we use is for standard image taking using ffmpeg (because vlc can only handle one camera it seems) is DS-2CD2T12-i3 (http://www.hikvision.com/es/products_show.asp?id=9882)
The RTSP statement I/we use so far:
- rtsp://admin:12...@192.168.1.12/MPEG-4/ch1/main/av_stream
We are not using GStreamer Plugin as far as I know. I am checking with my programmer and if I have something, I get back to you.

Thanks a ton for your prompt response. I really appreciate it.
Is this rtsp statement (below) also good for fetching live stream at say 20-25fps?? or it is used only for images?
- rtsp://admin:12...@192.168.1.12/MPEG-4/ch1/main/av_stream
My only requirement is to get live feed from my camera into my cpp/c code on Linux system. Really appreciate all your help. Mean while I will try the above rtsp statement.
Thanks again for all your time and effort.

Hi Mikael/Atchayagandhi,
Its interesting to know that you guys are working around ALPR for recognizing the licence plate number for Indian cars.
What my experience says with alpr is that, it works good for foreign number plates where licence plate are in a definite order and fonts. I have worked on UK number plate in my masters project and it works good with proper parameters. Unlike Indian plates which has way more problems like different fonts, orientations, dust, different size of number plate etc. Highest accuracy ever achieved practically on Indian plates is around 75%. Only 1-2 company claimed to achieve 85% but never proved it.
So are you guys looking for R&D or just trying to work around open ALPR?

Good Morning, we would be looking at a solution which want to market in India.
A bit more information on the ALPR would be great.

You really need to discuss with him directly because we agreed he can sell in India on his own. We are missing ALPR but will start on that soon. Perhaps OpenALPR combined with OpenCV is the way to go? OpenALPR also offers a commercial solution.
Email Atcha privately. I am sure something can be worked out between you two :)

Lag: IP cameras do have lag but 1 sec in video seems too much. Perhaps memory allocated from OS or decoding software itself? We use VLC (single cam) and ffmpeg (Atcha got that one working) for multiple cams. That is an area he could help you probably in return for some ALPR know how :)

to train its not problem, just need time to train data
more plate and image it will be more accurensy...

Hi,
I am looking for some ALPR solution for Indian market for one of my clients. It would be great if anyone can guide me on some solution. I tried openALPR but it is not working due to Tesseract version 3.0.4. The tesseract devel version was not available in homebrew.

Hi Vladmir,
I'm trying to develop a solution for traffic law enforcement in India that requires accurate and reliable APNR technology. Could you please share how accurate openLPR is for Indian number plates? I've gone through the mail archives but the current accuracy or what sort of help you need in training such as more images wasn't clear.
Thank you,
Sriram
