Hi all, I am trying to use LabVIEW to calculate the volume of a drop that I'm imaging. I've been able to do this successfully before when I was using a camera that I just "snapped," but now I am using a motion sensor to trigger the camera when the drop falls and now my code won't work - I'm assuming because due to the trigger, everything is within a loop? I'm not getting any output values for the volume, or any array even when I export the array to Excel. I attached the simple code I was using for the triggered camera and also the code where I added in the image analysis, although this is working to capture an image but not to calculate the volume. I don't know if it's necessary that I explain what the image analysis part actually is but in case it helps, I first convert the image to an array, converted pixel values within a certain contrast threshold to 0/1s, then scan each line of the image to find the edge of the droplet and calculate the diameter of the drop at each given point. I use those diameters to calculate the entire volume of the drop in voxels, then use a ratio of voxels/volume to calculate the volume. I appreciate any tips you can give me! I assume it's a quick fix but I can't figure it out... Laura

Good point.. I'll also try inputting some pre-made arrays and see how that works.

Thanks for all your help Burito!
