I recently received some feedback on the project I worked on which I noted earlier.
I can't go too far into details probably because it's all NDA stuff, but needless to say, a random rolling shutter video off Vimeo of the site gave me an accurate enough point cloud to generate my project with.
The real life data collected for their intended purpose matches what I provided for them to utilise in a simulated environment which is very reassuring from my perspective.
I'll have to give some rough numbers for it to make sense, but I'd guesstimate at a drone flying about 75m high with the camera looking forward about 35deg-45deg along the direction of travel.
Over about 200 images from the video, and about 2km, I had very little vertical or lateral drift... to the point that I went with the point cloud data for xy and z, over the formal xy plans which were obviously vector based, based off aerial imagery, but with the issue of height parallax distorting features that moved up/down in altitude over the location.
In the end I dumped every 30-40 frames iirc, so I'd go as far as saying something like a Ricoh GR on 1s interval without the rolling shutter issues, and a higher resolution and quality outputs, would result in superior quality results by far.
I just wonder if the DJI Phantom frame could work nicely with a Ricoh GR. Hmmm.
Cheers
