I want to get a height profile of white water droplets on a surface. My plan is to project a line laser perpendicular on the surface and observing it from a 45 degree angle.
As seen in the image below I've manage to isolate only the red line and one can clearly see the bump in the line which represents the water droplet. My plan is now to determine the height of the droplet but I can't find a way to remove the noise on the line in a fast manner. I'm still new to OpenCV and any suggestions will be greatly appreciated.
