Thermal image processing

Now you have a 2D array with all your pixel values. Use array index function to access each pixel value using the 2 indices of your image. You can build a VI for example that would plot in 2 waveform graphes the pixel values of one row and one column of your image corresponding to a cursor that you would manually move on the intensity graph.

I believe code similar to what I posted in this thread would allow grabbing the point under the mouse that could be scaled and displayed.

Here is an advanced version of what I mentioned above. It is pretty old code that I just cleaned-up a little bit but you should be able to use it, either by loading a comma-separated file of your own data or by copying the code into your own code.

The default data is a multimode CO2 laser beam. The cursors can be moved to plot on the waveform graph the laser beam profile between the two cursors.

Thanks, Marc Dubois

I need to find out the width of the region with high temperature that is my region of interest (ROI).

If I find out first and the last index of pixel with high temperature than i will get my result.

The picture is attached.

Thanks Ben

Actually, all process is carried out in a closed room because of high power laser. I cannot see the process during laser cladding because my system is inside that room. I have to store all the results.

So, I do not need a program which shows me value under the mouse.

Thanks again.

Why not use Particle measurements after you threshold the image?

Thanks, everyone.

I have found an easy solution to measure the width of my region of intrust.

I am Just using ''Count and Measure Objects'' VI available in  ''NI Vision Development Module''
