Dust particle measurements

[nanakwabena]

Hey guys,

I have a project I am working on and I need to use NI Vision to determine the movement of dust emissions and probably add some measurements.

Can you guide me on how to use the application to detect the movement of the dust emissions.

Best regards

Philip

Maybe you could try optical flow. Have a look at the examples.

Optical flow (as SamiF mentioned) might do the trick, however, the hard bit is usually capturing images of small particles, like dust. Have you solved the imaging side of the problem?  There are many factors, that tie into required resolution, and frame rate. Tracking in 2D or 3D.  Realtime, or post processing.

As an alternative to optical flow, I would explore object detection followed by particle tracking.

The imaging setup is going to be critical.

Illumination is number one. You need good illumination optimized for your task.

Then you need a decent camera. For particle tracking you need a camera running fast enough that your dust particles don't move too much between frames, or blur in the image. 

Good luck!
