I have spent some money and a great deal of time trying to persuade the mighty Inspire to perform this task. The idea is to take the advantage of Zenmuse X5 ability to shoot pictures with longer lens - say, 25 mm - and stitch high resolution spherical image in result. This approach requires 6 rows of 12 pictures each, plus 4 nadirs and 4 additional zenith images. No way to do it manually with one flight battery ...
Well, I must report that my experiments with few presumably capable applications aren't too impressive by far ...
Venerable Litchi app simply can't do the job with Inspire 1 because the bird is drifting significantly during sequence shooting. GPS is holding the position for particular row shooting with rotating gimbal, then the drone drifts with the wind like in ATTI, then stops to shoot next row etc. For 12x6 sequence she can drift in steps good 50 meters in mild wind, delivering impossible to stitch pictures. Accordingly to Litchi tech sup this is known issue with Inspire 1 and Phantom 3 series due to some FW bug. Hmm ...
Autopilot is offering truly impressive set of features for pano, but the execution is awkward with step learning curve. One must figure out and determine way too many exotic parameters, both in general app settings and in Panorama mode settings before engaging pano shooting job, and gimbal behavioral settings are hard to understand. It's promising, but way to complicated.
DronePan app (free) seemed to be the simpliest and sufficient enough. You fly to a desired place, set the position and picture parameters in Go app, switch to DronePan and execute pre-programed sequence. Done. Well, unless the app is displaying the warning "can't determine gimbal attitude" ... ? ... End of story. Apparently 3-axis Inspire gimbal is the troublemaker, an feature too confusing to all pano-capable applications.
DJI Go 4 app is offering nicely crafted Pano mode for Phantom 4 Pro. Single spherical sequence contains 34 images neatly stored in folder on SD card, one battery allow for shooting 4-5 alternative sequences of JPEG+RAW images. The quality of over 300MP stitched full sphere image is astonishing, when done in Autopano Giga or PTGui software. Said that, it's not what I'm after ...
It's is unlikely that DJI will implement Pano Mode for Inspire 1 within Go app, which appears to be obsolete and neglected. Meantime I'll try to master what Autopilot has to offer in this department and post my conclusions here ...
EDIT (Aug 14/2018): Loudly advertised on YT and very promising HDRpano app finally appeared in Apple store ... Sadly this application is only half-cooked and simply doesn't work reliably enough, at least with my Inspire 1 Pro and Matrice 200 drones ...
EDIT #2 (Sep 10/2018): All of the above doesn't apply to Inspire 2. Once I've purchased this bird, even the most elaborate full sphere panoramic shootings are performed nicely with yawing gimbal under Litchi 2.5.1 control. Mission acomplished, finally.
