LabVIEW
Is it possible to record mouse coordinate into array?
Solved!
Sorry, I don't have IMAQ installed, so all I see is broken code and unknown events.
Just comparing with my code, The logic does not seem right.
In the "mouse up/down event", shouldn't the new time after the select go to the selector of the case structure?
In the "mouse move" event", shouldn't you ignore the type and just read from the shift register?
Similar to the following?
Ok then , I will learn more about this , thanks so much for the help !
by the way, do you happen to know how to get the coordinates of a contour ?
- What it should look like :
- What I did (It's too much, it counts every x pixel):
- Is it possible to get the yellow boxes' coordinate? (I'm using Clamp(Rake) function.
As I said, I don't have IMAQ here, but I would just make my own algorithm using plain LabVIEW.
For example if all contour points have unique x values, I would just go over all image columns and look for the step transition, then fit them to a suitable polynomial or other function. How much do you know about the shape?
Do you have a raw image? (i.e. without the red markers?)
See if this rough draft can give you some ideas. (most likely you need to tune and polish it. adapt to your specific image type, adjust threshold, reject outliers, smooth using polynomial, etc.)
