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