Using Trimble UX5 drone I have collected photos of pit site and processed it with Pix4Dmapper Pro Trial, UASMaster Lite and Agisoft photoscan Pro.
Report from Pix4D http://www.filedropper.com/krivaiciaireport
Point cloud files was imported in AutoCAD Civil 3D software. And TIN surfaces was
compared. Most of site was in 1-3 GSD accuracy, but not all. Location on a slope have up to 4 meter difference. And it was steep slope. So, accuracy depends on the steepness of the slope? And how much it depends?
I have processed photos using Pix4Dmapper Pro few times and compared results. Got the same results as comparing Pix4Dmapper results with other software results.
So if I process photos with Pix4Dmapper Pro many times with same settings I will get different results? Different in flat location will be 1-3 GSD and in steep slopes will be big?
