What are you talking about?

Please provide more details as to what you're trying to do. What version of LabVIEW? Are you using specific tookits?

Ok, as far as it seems, he is using Vision since OCR is Optical Character Recognition which is provided with IMAQ.

But you should provide more informationb for us in order to help you!

Note: You can "train" certain characters and export that to a file (for instance by using IMAQ OCR Write Character Set File VI)

Later on, you can import that set by the appropriate Read File VI.....

You need the Vision Development Module for OCR. If you have this, please refer to the help of the OCR functions. If you do not have it, i suppose that it is less cost intensive for you to purchase the module instead of reprogramming the functions......

Thanks for the replies. I have already installed the Vision Development Module, I have reviewed the example of OCR and would like to know how to create that file.

Here is one easy way. Actually i create it like this everytime.

1. Open vision assistant

2. Select identification--> OCR/OCV

3. Select new character set file.

4. Now selct the character you will see ????.

5. Train the characters.

6. Check for consistency

Note : You can also play with the settings

7. Create a labview vi from vision assistant.

Hello everyone. I would like to help me, show me how to create an image of 8 bits to use in OCR. When testing, VISION Asistant requires that images for training are of 8 bits.
Thank you.
