Good afternoon everyone,
To introduce myself a little, I am Dave, I use drones to study the spatial ecology of marine species. I've used the phantom and mavic in the past to do some standard mapping work to make 3D models and orthomosaics. Now, I've recently got a hold of the Matrice 4E to undertake a new project to measure some small critters in the intertidal - I'm new to this drone, and also to using RTK so I'm on a learning curve at the moment. I have to fly close to cliffs and use the 70mm or 168mm camera using a manual flight (imagine you have to move the drone up and down with the rhythm of the waves - quite high risk surveys).
I'm having a major issue at the moment, I am using these images to create 3D models in Agisoft. When I import the images into Agisoft, I get lots of warnings about digital zoom. which is especially problematic in general and was amplified when I tried to use images from the 70mm and 168mm in the same project, it's a mess!
After further investigation, the Exifs show that the 70mm has a digital zoom of 1.12 and the 168mm has a digital zoom of 1.01. No matter what I try, I cannot seem to set the zoom to 1, I have tried it manually with the wheel, I've tried using the R2 and R3 button to set the zoom level, neither seem to make a difference. The wide photos are locked nicely at 1 (ie no digital zoom).
Has anyone got any ideas how I can deal with this?
In an ideal world, I am trying to use the zoom cameras to make the models, but also supplemented with some wide camera images to make sure the whole scene clicks together in the case my zooms didn't get the sufficient overlap dropped (as mentioned its a fully 3D scene with manual flights)
Also a quick add on question, as mentioned I am new to using RTK - if I have RTK enabled and connected to the drone (through either NTRIP or with the RTK3 station), what are the coordinates in the image EXIFs? GNSS or RTK positioning?
Thank you for your time,
Kindest regards,
Dave
