I have tested DJI GS PRO, the solution is promising, even if the application is still experiencing a number of teething troubles:
For instance, in 3D Map area mode, the aircraft keep the same heading during the mission: therefore, all the picture are taken in the same direction.
The management of the map stored in the cache memory is not yet stable.
Whatever DJI GS PRO is well designed: interface ergonomics is good and there are lot of possibilities regarding parametrization.
This video (in French with subtitle) is a tutorial and a test with the Phantom 3 Pro, Inspire X5 and Phantom 4 Pro.
"For instance, in 3D Map area mode, the aircraft keep the same heading during the mission: therefore, all the picture are taken in the same direction."
Could it be that it would be most handy to keep the same direction in space when doing a mapping overlay. Otherwise the pictures in the adjacent track flow would be turned 180 degrees.
In the "waypoint" mission planning there are more options of heading control, either being "course aligned" "define per waypoint" or "manual control" and the turn direction can be preset at each point, weather it should be clockwise or counter clockwise.
Hello Ricci2 and Niland thank you for the comments,
Nil, you are right as well and actually I have no clear-cut opinion on the best behaviour during 3D mapping because it should depends on the object of the mission.
Crossing pictures (in order to have all the sides of a building for instance) needs to plan 2 missions while with existing applications (as Pix4D or DroneDeploy) its not required because the heading of the Aircraft follows the direction of the path.
Maybe an additional parameter could address that in next version of DHJI GS PRO.
Hi, this video present the full workflow (from GS PRO to PhotoScan), and a method to shot properly a monument from the side (as the 3D Map POI function is not yet available).
