I made a model of my usual drone testing area using the Smart Oblique option.
The gimbal rotates the camera in 5 directions to ensure coverage and overlap.
Only 51 images were needed and I only had my target directly around the building.
It easily captured the building and some of the surrounding area and I am impressed with the building itself.
This proves that with photogrammetry, more images is not always better. You just need proper overlap and coverage along with sharp images.
Link to 3D Tiled Model in Cesium format:
From this ouput a point cloud was made locally on the controller, in which I planned a mission to capture the same building in a later flight with an eye watering GSD of 0.20 cm.
This yet to be flown mission will take ~1800 images and should have a photorealistic model to include under the eaves.
I will share this super detailed model after I complete the mission. It has been too windy to attempt this since the drone will be between buildings and there are powerlines and thin items to account for.
Local Point Cloud - Notice that it captures the thin antennas on the roof, flag pole and utility poles. This will help to ensure that the flight plan accounts for them for flight safety.
Flight Plan - Notice that the flight lines avoid the flag pole and roof antennas. It is pretty awesome that this point cloud recreated them so that the flight lines can be made to avoid them.
