Here’s a description of how the dataset is captured.
The smart oblique feature allows photos to be taken at multiple angles during a flight by way of payload control. All the ortho- and oblique photos necessary for 3D reconstruction can be acquired through one flight path [ie lawnmower vs needing to fly a grid]. Only photos essential to reconstruction will be taken at the edge of the flight area, minimizing the number of images taken and significantly increasing the efficiency of post-processing. As each flight area corresponds to a different flight path section, which requires a distinct oblique capture strategy, all the photos taken for each flight path section will be based on the target data collection zones demarcated by the user’s measurement area. During a Smart Oblique Capture operation, the aircraft will fly in the mode with the highest operational efficiency. The flying speed will also be adjusted according to the different oblique capture sequence for each flight path section, to maximize the efficiency of the operation. Currently, the function is only supported by Zenmuse P1 as mounted on the M300 RTK. To use the function, enable it in aerial photography settings for flight path navigation on the DJI Pilot app.
The system is mechanical shutter and the oblique photos can be anywhere from 90 to 45 degrees.
