Today’s question is about 3D mapping. Do you need to introduce multiple orbits for making an accurate 3D model with your drone? How can you map overhanging structures? What makes Phantom 4 Pro the best drone for UAV mapping?
In our 800th episode, we suggest ways via which you can excel in 3D mapping with your drone. Do you need to introduce multiple orbits while mapping a complex structure? Learn how you can deal with this increased complexity in 3D mapping. We also discuss how you can get survey grade data using photogrammetry.
Next, we talk about the best drones and cameras for UAV mapping. How does the Phantom 4 Pro compare to the Yuneec H520 for UAV mapping? Learn why global shutters can help you achieve greater accuracy in 3D mapping. You will also receive some great tips for processing your data. Can you process vertical image captures with other ones? Tune in to find out. We thank Simon from Norway for the question. Fly Safe!
