This article explains the steps to remove an object from a stockpile in PIX4Dmapper.
It is possible to remove an object from a stockpile to acquire accurate volume measurements. The volume is computed based on the DSM, therefore the DSM should be generated without considering the object.

To remove an object from a stockpile and achieve accurate volume measurement:
1. Process steps 1. Initial Processing and step 2. Point Cloud and Mesh.
2. Edit the point cloud to delete the points of the object, following: How to edit the point cloud in the rayCloud.
3. Process step 3. DSM and Orthomosaic to generate the DSM.
4. Click View > Volumes to access the Volumes view.
5. Draw a volume, following How to draw a Volume and click Compute to compute it.
Note: If step 3 is already processed and the DSM is already generated, it needs to be processed again so that the DSM is updated for the changes in the point cloud. In this case, the DSM and the Orthomosaic should be moved to another directory so as not to be overwritten.
Hi
Can you help me out with the steps to follow in order to calculate the volume by removing trees that are in the way of stockpiles. I followed the following steps and nothing happened. Point out if theres something wrong.
1. Initial processing and point cloud and mesh formulated
2. In the "ray cloud" activate point clouds and "edit densifies cloud editor" was used properly and assigned to a new point cloud.
Then what to do ? Exactly, the tutorial do not mention what to do.
One video showed I have to follow the below after deselcting the point cloud in the "ray cloud " point groups
Process -- rematch and optimize
It seems that you followed steps 1 and 2 of the above article correctly. After you delete the tree points (point group "Deleted"), you need to save the project and process step 3. DSM and Orthomosaic to generate the DSM.
Once the DSM has been generated, you can calculate the new volume (without the trees)
If the stock pile is covered with plastic film and on that film there is some sand keeping plastic on the stock pile. Can i remove or off calculate that sand somehow? There is not sand all over the plastic, only a sides so I can see the most parts of the stock pile.
Hello Ville,
It is possible to calculate the stockpile under plastic if you remove the sand you don't want to include.
The following are the steps to calculate it,
1. Process steps 1. Initial Processing and step 2. Point Cloud and Mesh.
2. Edit the point cloud to delete the points of the object, following: How to edit the point cloud in the rayCloud.
3. Process step 3. DSM and Orthomosaic to generate the DSM.
4. Click View > Volumes to access the Volumes view.
5. Draw a volume, following How to draw a Volume and click Compute to compute it.
