Computed camera position seems to be off

[mbcallihan]

Hi,

I’ve been processing my field data and have come across a problem with processing one of my flights. When I complete the 1. Stage processing and rerun after adding my GCPs, its doesn’t calculate the camera position correctly. The elevations do not match what they should be like. And I get a weird warped, boat-like return. When I run it on full processing its much more warped than on the rapid processing. Is there something I am doing wrong? I’m still pretty new at processing this data. I’m using verson 3.2.23. I’ve processed multiple flights flown by my Mavic Pro 2. This flight was flown with a Phantom 3 Pro. I am going to be merging these different flights into one larger one and want to make sure everything is correct before I start that process. I’d appreciate any help on this, maybe someone else has had experience with this?
Thanks, Melanie

Hi Mélanie, @mbcallihan,

There is some known issues with the Mavic Pro 2.

Pix4D Mavic 2 Processing Issues

Best Solution (as of the time of this edit):  Upgrade to Pix4D 4.4.9.  As of the time of this edit-entry it isn’t part of the automatic update but is available at https://cloud.pix4d.com/download/ Hey Guys,   I just got the new Mavic 2…takes great pics…but I’m having issues processing these scenes.  The GPS coordinates showing in the pictures actual files are correct…but they translate incorrectly in pix 4d Below are the pix4d results from processing the Mavic 2 photos…the red are where the s…

There has been some fix for it in later Pix4Dmapper versions:

Technical release notes - PIX4Dmapper

The Mavic 2 Pro camera ha sbeen added in the 4.3.31 version and fixed in the 4.4.9 version.

Could you provide us the quality report of your project in your reply?

I would also recommend you to have a look on this topic:

Curved Output after initial processing

Hi Everyone,   Does anybody here also experience what have happened to me. The result is somewhat odd because the result show a very curved tie points. In reality it is a relatively flat terrain.   Please check on the attached pictures as your reference. I also attached the flight path to show that this only happens when the project area is like a rectangle which the length is much greater than the width, e.g. road, rivers. It is also my second time showing this odd result. With different da…

Let me know if you managed to get a proper project.
