Hi Nigel

If you make a sample for Automatic Number Plate Recognation (ANPR and change to text.
It is very useful for many software for example Parking,...
I tested GetRussianPlate demo and it only detect and crop plate.

Hi Ali

The demo you suggest above is joining to simple demos together. It is quite straightforward, so please try it and let us know if you have any difficulty.

Hi Nigel

I have a offer for you which it is useful for many developers.
You have a lot of experience in image processing.
Please create a sample plaque reader that crop (separates) the plaque image and converts the plaque image to text.
Then I'll do the whole test for you and report the results and problems.

Best Regards

Hi

Please download the "pixelize plates" demo:

http://www.imageen.com/files/Other/PixelizePlates.zip

Which returns the rect of each number plate in image.


Then review the source code for the OCR demo (in the IEVsion\OCR\ folder):

    // create OCR object
    m_OCR := IEVisionLib.createOCR(PAnsiChar(AnsiString(langPath)), PAnsiChar(AnsiString(langCode)), TIEVisionOCREngine(cmbEngine.ItemIndex));

    // set page layout
    m_OCR.setSegmentationMode(TIEVisionOCRPageSegmentationMode(cmbLayout.ItemIndex));

    // perform OCR
    ocrrect := ImageEnView1.SelectedRect;
    memo1.Lines.Text := m_OCR.recognize(ImageEnView1.IEBitmap.GetIEVisionImage(),
                                        IEVisionRect(ocrrect.x, ocrrect.y, ocrrect.width, ocrrect.height)).c_str();


Change the ocrrect := ... line to use the rect returned by the "Pixelize Plates" demo.


It is quite straightforward, but let us know if you have any difficulty.

Hi Ali

Try pairing it with the OCR demo to convert the area of the plate to text.
