Depth difference of dense point cloud models

[kennyfok2009]

Hi all,

I'm uni student, currently doing a project about gully erosion with photogrammetry monitoring.

I have 2 dense cloud models, one is gully in May and the other one is gully in Sep, and I'm looking at their differences between time.

I already get their volume differences but just wondering is there any methods that I can get the depth or width difference between 2 models?
(I have ESRI software in my own desktop if I need to use that to do this)

Thanks
Kenny

Thanks.
Do you have some tricks to use it?
Cuz I exported as .obj file and put it into cloudcompare, just shown as planar object.
And I googled or searched some tutorials on youtube, their models come out very nicely.
So, if you can give me more tips on using cloudcompare, it'd be great.

Thanks again

There is a specific video on you tube showing how this is done in cloud compare, havnt got a link to hand, but am sure a quick search you will find it
