Rotating OCR

[Jaime Rodriguez]

Im working on an application where I have to perform OCR on images, but the ROI move within the image. I know how to set a coordinate system for dimensional Image Processing (Find Edges, Fins Circular Edge, etc.). However the READ OCR.vi does not have a Coordinate System input. So how do I make my ROIs move with respect to a pattern that is on the image? Do I have to do this changing of the coordinates manually???? The dimensional processing vis, have the coordinate system inputs which make it easy, but doing it programatically can be a pain!!! Can someone help me???

Jaime,

To the best of my knowledge, OCR only works on unrotated text.  If your text is at some arbitrary angle, you will need to rotate the portion of the image containing the characters so they are horizontal.

A coordinate system input for the OCR tools would be a very nice addition.  I would like to see the ability to define a rotated rectangle ROI, and have the OCR know that the axis of the text matches the axis of the rectangle.
