recognise bmp using OCR

[Kumar]

Hi,

I would want to recognize characters and number captured by CCD camera in BMP format using the NI OCR. How do I go about doing this. Is there any sample programs which might be of any help?

Thanks
Kumar

Hello Kumar.

It is definitely possible to do this using our IMAQ Vision Development Module and the NI OCR addon. There are a couple of general steps to performing OCR:

1. Perform the 'learning process' so that the characters are stored for use in the algorithms.
   This is accessed as a program that is installed in the National Instruments program group on your machine when you have OCR installed.



2. Start recognizing characters! Getting started with this can be accomplished by looking at one of our shipping examples, or by using the Vision Assistant to prototype your application. There are several examples that are stored in various locations on your machine depending on your development environment. For LabVIEW, there is an example found by
   going to the NI Example Finder (Help&#187Find Examples. . .), selecting browse 'By Directory Structure,' and navigating to Vision&#187Functions&#187OCR.

Importing BMPs into your program for use with our OCR or Vision algorithms is as easy as calling a VI/function and reading in the file. Again, the specific examples depend on whether you are using LabVIEW or another environment. If you are using LabVIEW, the NI Example Finder has a lot of great examples to help you get started with your application.
