Orthophoto missaligned


#1

channel Hello, can you tell me why my orthophoto is missaligned with the map? is it my compass?


#2

It shouldn’t be your compass — OpenDroneMap doesn’t pay any attention to your compass. Can you plot your image centers and see where the GPS of the drone thought you were?

channel Thanks smathermather, I traced the real position of the channel in yellow


#4

Understood. Can you extract the camera positions and place them on the map?

Also, are you using just exif data or are there GCPs involved in your processing too?

  • Camera Position:
    199354.45, 1552830.12, -0.88
  • Camera Target:
    199358.65, 1552878.04, 5.03

And no, I can´t set GCPs yet but would love to do it w/out more hardware, any cellphone app advised that can do it?
