I am trying to use CR for Stock pile Quarry volumes and I am having issues with Height Accuracy. I use a DJI Phantom 4 Pro. I have brought the GPS Images in and also Ground Survey Ground Control Points in and chosen the Points and then re-aligned and then ran the processing.
But the Heights aren't the same as my CGP Points I bring In.
One of My GCP's as i have imported it.
1 CROSS6MM,407786.3600,348541.3960,290.78400 ( Height Being 290.78400)
The Eastings and nothings seem to be correct just the height is a problem.
I have tried to not use the Exif data from the images from the drone but that seems to only make a slight difference.
But I then export the point cloud to a 3rd Party software N4ce and the highest point is only 200 Metres in the image below the e: 117.76m I assume is what it thinks as the height although I have told it to be 290.784.
Am I doing something wrong on the workflow somewhere. I would be really so glad for any help that anyone can point me in the direction of.
Is anyone using the point cloud for stockpile volumes and getting the required accuracy ?
Thank you very much
