I commented late last year about DJI becoming a camera manufacturer… this is an interesting and exciting move simply because the quality of imagery from drones has lagged significantly behind the rest of the camera industry. So whilst there are clearly regulatory challenges that need to be overcome through hardware and software engineering, the end-user is interested in the best visual imagery possible and drone manufacturers are starting to wake up to this fact.
So I was surprised to see that SeneseFly had announced back in 2016 its (then new) eBee Plus offered an hour of flight time within a ~1kg airframe that can incorporate RTK/PPK positioning (forget those ground control points!) and multi-spectral/thermal. But… they have also introduced their own homegrown air camera dubbed SODA (Sensor Optimised for Drone Applications). It is extremely light on specification however their website notes its a 20MP 1” fixed lens camera. This that likely utilises Sony’s standard 1” sensor, although it would be useful to clarify the exact size. Is it genuinely 13.2×8.8mm? Taking their GSD example figures, that breaks down to a 10mm focal length lens, equivalent 27mm on a full-frame camera. Interesting there is a single global electronic shutter which is a good thing for a fixed-wing aircraft: it should stop the problem of a rolling-shutter.
Fascinating to see the drone-camera market develop and it’d be great to see some results from this baby.
Earth-i has just launched a new SSTL built satellite which is claimed to be the first to provide full colour UHD video - UHD is 3840×2160 pixels (8MP), shooting at 50 fps (compared to Landsat 9’s ~12,000×12,000). That’s a lot of downstream data, although it would appear it’s not the video they’re interested in, but the multi-temporal data. Think super resolution to give them an effective ~70cm pixel size, but also stereo (and so 3D). This is the first of a planned 15 satellite constellation which could provide global coverage and much more agile mapping capabilities. Video is clearly the new high resolution!
