I’m about to make a first trail on volume measurements for a potential customer. I’m used to drones, but not the details to capture the picture needed for the 3D model in Pix4D. I have read a lot about it and seen many videos so I got a rough idea about the process.
Goal: Provide a reliable volume measurement (one stock pile) for a potential future customer.
I’m planning to use my Phantom 3 PRO and the Pix4D app.
I will not use RTK GPS to determine the exact GPS location of GCP. Instead I’m planning to measure the exact distance between 3 GCP using laser. That should make it possible to set the scale of the 3D map correctly?
I will fly a double grid pattern and use 80% overlap.
I’m not sure which height I should set. And I don’t know what camera angle that would be optimal for this kind of work. Any suggestions?
