Measuring volume of grape vine berries

[Uhu]

Hallo everybody,

I have a point cloud of grave vine and my aim is to measure the volume or diameter of the berries.
I have no experiences with Cloud Compare. Maybe some one knows the best way to measure this?
I am thankfull for any ideas.

What does the scan look like?

[Uhu]

Thank you, for your respond.


We take photos from different angle of the grape vine. The photos are georeferenced. With the software Agrisoft Photoscan we converted the photos to a point cloud . And know we have point clouds of the howl plant, with stem, leaves and a white background.


Is this answer helpful for your?

I was expecting a snapshot but I get it.

You can try the 'RANSAC shape detection' plugin with only spheres. Hopefully it should detect the berries. See http://www.cloudcompare.org/doc/wiki/in ... n_(plugin)

Yes would be easier. I attached a file with a screen shot.


Thank you. I think i have try around for the best settings

Ah, the berries are quite small. Can you maybe segment a grape and zoom in? (it would be better to test the plugin anyway). How many points do you have approximately by berry?

[Uhu]

Around 450 points per berry.

[daniel]

Okay, not that bad... How does the qRansacSD plugin performs?

[Uhu]

im not so happy with it.

I tired the tool compute 2.5D volume. I think the values of this are in the right range. IS this a valide tool for my purpose?

[daniel]

Hum, the 2.5D volume would work for a terrain, but definitely not for berries!

Can you maybe share the cloud with us (the small portion)? As a link on the forum or directly to my email address (admin[at]cloudcompare.org).
