Karkanov Posted April 25, 2010 Posted April 25, 2010 Hi Everyones, I need to read the number of X Axis, Y Axis and Z axis on the screen I've attached, I tought to use tesseract to convert the number to text, but the thing is the PC where the software run is on Windows Nt4 SP6, I can't get tesseract to work on this old PC, Does anyone know if it possible? what should I do? If you have better idea how to do that I'm open to all suggestion. Thank You Karkanov
JohnOne Posted April 25, 2010 Posted April 25, 2010 Try using the control commands, after getting the info of the controls autoit window info tool.I imagine that if you can get tesseract to operate then you know how to navigate the helpfile.Try some code and dont hesitate to ask if you are having trouble.

AndyG Posted April 25, 2010 Posted April 25, 2010 Hello, I´ve written a tool to "solve" problems like yours by comparing images. To detect the right "characters" it is helpful to have a constant colour in the background of the characters. The background of the characters (the numbers you are looking for) in your picture is not evenly in one colour. Are the different colours due to the compression-artefacts of the jpg?

Are the different colours due to the compression-artefacts of the jpg?The background is not the same, because they are "control object" BUt if I try to read the control value for some reason I don't get any value, it's like the windows don't refresh the value everytime it changes. Do you need to teach your tool every character before use it??

I'll copy the final result in few days.
