One of the new photo modes now available with the DJI Mavic Air which was released in January 2018 provides the ability to generate “32MP Sphere Panoramas”.
In addition to Horizontal, Vertical, and 180° panoramas, the Mavic Air can stitch 25 photos together in less than 10 seconds to create Spherical panoramas… it will even auto-fill the Zenith (the “hole” at the top)…. But is it really as good as it sounds ??
I did some tests and compared the autostitched panoramas with those created manually (with specialist 3rd party software)… with some interesting results.
The automated process used by the Mavic Air to take the 25 photos used for the panosphere is very fast and efficient, and for the most part, the individual photos are excellent (although I did experience some exposure issues which I will need to investigate further).
At first glance, the autostitched Panosphere looks reasonably good…
However, once you have a closer look, there are a lot of stitching errors and blurs where the individual photos are joined.. There are also some exposure inconsistencies and the way that the Zenith (hole at the top) is patched is pretty ugly.
Here are a couple examples of some of the stitching errors :
and here are samples created by manual stitching the same photos using PTGUI
… and here is the Photosphere manually stitched, using PTGUI, with the Zenith patched, using some custom scripts and Photoshop, and loaded up to Google Maps :
In conclusion, the Mavic Air is quite capable of taking reasonable quality photos for use in an aerial Panosphere… but don’t rely on DJIs auto-stitching… a manual stitching process will give MUCH better results.
