Sorry for another image-intensive thread!
This is a continuation of the discussion here
For comparison I’m using a DJI Inspire 1 with the X3 camera with, in this case, the standard lens (no ND filter) and manual camera setup. Due to the required flight characteristics the mission is not flown in DroneDeploy. In this case the orbits were flow in AFL and the grid in MME. This was to provide the required granular control of height and overlap around the tall structure and orbital helter-skelter path. The mission was flown at around 7kts with a 2 second / shot camera, which is as quick as the SD card allows. The resultant flightpath looks like this:
The structure is a 90’ granite monument to local miners built between 1757 and 1835 atop a 650’ high neolithic hill fort dating from 3700 BC and it’s full of interesting, fun and challenging things to throw a bit of SFM math at, so we considered it a good test for this.
The flightpath resulted in 291 images of which 144 were nadir and 147 were oblique at 45° camera angle. The results were processing in Pix4D and DroneDeploy. Processing took about the same amount of time on both platforms, but I have a good workstation. DroneDeploy processing was done as a Structure in Map Engine.
Following is a comparison of Pix4D and DroneDeploy output. Pix4D is first in each case…
