About the dataset preparation

[8acemak1rkey]

I have several questions , and thanks for your replay!
First, how did you get the UAV's vedio. Whether it's through Google earth pro's built-in video recording which takes really long time each building, or through other software on your computer, such as the OBS.
Second, how did you generate the kml file of the flight trajectory, by directly operating the Google earth pro software? I can't operate the smooth spiral descent flight, how to operate it to generate a beautiful kml file like yours?
Thanks for your reply!
