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 remote controller.
- Power on your drone and remote controller
- Open GS Pro and tap on the live camera feed in the bottom right corner
- Ensure that the camera is set to focus for every capture (green square, tap to change)
- To the right, make sure that autofocus (AF) is selected in blue (as opposed to manual focus (MF))
Tap on the Camera Settings icon and adjust the following:
Camera Mode: S
Switch to the camera icon and adjust the following:
Capture Mode: Single
Image Size: Ensure that your drone is in its native aspect ratio. For a Phantom 4 Pro, this is 3:2.
Image Format: JPG
White Balance: Sunny or Cloudy, depending on current conditions
Switch to the gear icon and adjust the following:
AF Assistant: Disabled
MF Assistant: Disabled
Front LEDs Auto Turn Off: Disabled
Mecha. Shutter: Enabled
Tap the map view in the bottom right corner and then tap the Save Default Settings button. Any future missions will now utilize these settings by default.
There are many settings, so why are these the important ones?
- Autofocus: 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!
