Calculate volume in complex silo

[Théo]

Hello,
I've already tried CloudCompare to calculate volume of stockpiles on the outside, but I have a problem for one particular stockpile. This stockpile is located in a silo and the bottom of this silo isn't flat but cone-shaped. We wanted to scan the inside shapes of the silo when it's empty, but it's not possible because the factory cannot work if the silo is empty. We thought about implanting a 3D shapes of the silo, so that it could be considered as the "Ground/Before" of the stockpile that we need to choose to calculate the volume. Is it possible ? Or do you have any ideas on how to make such a calculation ?
Thanks for your help

If you create a cone (with the Primitive Factory, or even with an external tool as long as you can export it as a mesh file), then you'll be able to sample points on the resulting mesh/entity (with 'Edit > Mesh > Sample points') and then use this cloud as 'before' cloud?

Thanks for your return !
I did manage to do it by importing a mesh of a complex form of the silo into CC !
I have now another problem... It seems that, when I do a long flight with the drone, it sometime lost its way and I have for example two columns approximatively on the same place but with a small lag, instead of just one column. Is there in CC a correction for that type of issue ?
I think that another software I'm about to use for my applications can do something like that, to correct a cloud by using the previous data of the sensors during the flight.

Attached to the reply, a picture of my cloud for a stockpile where I (the pilot) am taken twice into account in the cloud, due to a lag.

Hum, not sure to see how this could be fixed in CC!
