How to remove Objects from a Stockpile for the Volume Computation

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. 

Volume with an object on the stockpile Volume after removing the object from the stockpile

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)
