Open target package and face up towards the sky such as above photo shows. The entire target case (both sides) must be visible. Make sure the targets are free of debris, if not you can typically blow the dirt off with your breath or brush it off with your fingers.
You can either stand over the target or take off with your drone near it. If you take off next to it, make sure not to cast debris onto the targets. You can also take off further away and then fly directly over it.
Make sure not to cast a shadow on the entire fiducial code and target area.
Capture a photo using each camera while keeping the target as centered as possible.
Try and keep the camera within 15 feet of the target.
Fly your survey directly after target image capture.
