The camera settings you choose before taking off can mean the difference between accurate, measurable data and a model that can't be stitched together.

This article takes you through how to set your camera to best capture your site.

Prerequisites:

  • DJI drone
  • DJI GS Pro installed on an iPad and connected to your drone.

Instructions:

  1. Open GS Pro and tap on the live camera feed to be able to access the camera settings.
  2. Ensure that the camera is set to auto focus for every capture (green square).
  3. Tap on settings.
  4. Ensure that your drone is in its native aspect ratio. For a Phantom 4 Pro, this is 3:2.
  5. Set the white balance appropriately. (In this case, it was a sunny day.)

Reasoning:

There are many settings, so why are these the important ones?

  • Auto focus: Without adjusting the focus for every image, the images will only be clear on at one particular elevation. Blurry pictures are catastrophic for photogrammetry.
  • Aspect ratio: The most useful parts of the photo are the edges of the images. When you set it to something other than the native resolution (usually 3:2 or 4:3) to something else (like 16:9), you lose vital chunks of the source images.
  • White balance: It's easier for the photogrammetry engine to stitch well-balanced images together—plus the resulting model looks nicer.

I still can't do it!
