If you can identify individual particles from the photos by image processing, or if the image intensity could be correlated to particle concentration (possibly due to mie scattering) then if you have photos over time, it is easy to find out the settling or accumulation rate.

Beeren Sahu

I am not sure how a photo can help you to measure accumulation rate. An image does not provide us the time information. A video might help you in computing the above more accurately and precisely.

Giuseppe Carlo Alp Caridi

I'm doing something similar. The point is to get the particle concentration [number of particles/unit of volume] and the particles velocity (with PIV). These two parameters allow you to estimate the particle rate, a sort of particle flux [number of particle*m-2*s-1]. The problem in the real cases is the non-constant concentration (the particle distribution in the volume is not homogeneous) and, in many applications a non constant velocity distribution. So, if you are not so far from these assumptions, you can retrive a good estimate of the particle flux (accumulation rate=particle flux * cross section). If you have a tomographic PIV setup (3 or 4 cameras), you can measure the particle distribution and the velocity of every particle (3D-PTV) in the overall volume of interest (if it is not to big). As a result, you get instantaneously the accumulation rate distribution in space.
