Dronee - How to set sony RX0 to get perfect mapping results.

Hi everyone,

I would like to share my experience with Sony RX0 which is a fantastic camera for surveying.

SonyRX0 zero is a small size, a shockproof digital camera with 25 mm wide angle (equivalent to 35mm)

It is only 110 gram with battery. Quality, size, wight make it suitable for surveying applications on drones.

Sony RX0 has a manual mode to set all camera parameters manually to get sharp pictures 

to get sharp quality pictures you should consider to set few parameters correctly:

Shutter speed: to remove blur from photo shutter speed should be set for higher value. 1200–1600 is recommended. Higher the shutter speed reduce image quality.

ISO: lower the ISO higher image quality. ISO between 150–300 is recommended.

Focus: Recommended to set the focus manually on the ground before the flight. Direct camera to an object which is far, and slightly increase the focus, you will see on camera screen that image sharpness changes by changing the value. Set the image sharpness at highest.

White balance: recommended to set to auto.

Dronee PLANE fully supports Sony RX0 camera and triggers the camera over onboard wifi.

Hi Tommy, 15 MP is weaker than usual 20 we use in mapping, we can balance that with more pictures, how fast can you trig ?

Hi Pascal P. 

To get the same cm/pixel high resolution drone mapping you will need to fly at 90% altitude of the regular flight you do with 20MP.(for the math : sqrt(16)/sqrt(20) =0.9 )

Meanwhile you can change survey resolution  inside the Dronee App Settings->Survey screen 

Sony RX0 is capable of triggering in 2sec intervals.

Pascal P. in what resolutions do you usually use in drone surveying ?

I do 2 cm and more. But 2 cm is difficult to get with plane or wing, due to speed and overlap. Sensefly Soda has even 2.9 sec interval, bad for low altitude high res mapping.

So the need for multicopters for these jobs, where a fast triger camera would suffice.

So are you saying the RX0 is only capable of 0.5 fps? Multiport control may be faster. What are you doing about precise feedback?

Comment by Tomi Piriyev on May 19, 2018 at 9:29am

Yes Matthew, using multiport does not improve the 0.5fps (as long as it writes to sd card) meanwhile it would be good for precision mapping, Currently, you can use Sony RX0 with wifi(on drone) triggering without any modification, also sony uses proprietary ptp protocol for its multiport. But we do take the feedback seriously, as sometimes sony may skip triggering, then the drone doesn't record GPS to the register. For precision mapping, we soon will have RTK/PPK version if you are interested, feel free to write your requirements through messaging on our website

I do PPK mapping and therefore would be interested in high precision feedback for the RX0. I hope you will do more than just assume a fixed time offset between trigger command and shutter. The 0.5 fps however sounds incompatible for fixed-wing speeds flying below 120m AGL, especially in high winds. Are you just flying low overlap?

RX0 is triggering 1 fps RAW or a little bit more, I'm using seagull map2 for this but you can build your own arduino and go to the limit witch I think is more than that.

Hi Tomi,

Do you find the way to capture feedback from rx0 camera when the camera is actually trigger for further geotag processing (such as emlid reach)?

Comment by Tomi Piriyev on June 1, 2018 at 12:59am
we do capture the feedback from rx0 for geotagging, but since we use off the shelf wifi API which can have latency 1-30ms triggering, we currently do not support RTK-GPS with this version, meanwhile, we soon will have RTK/PPK version for precision mapping 
You can use RAW mode with Dronee Plane, and geotag as well. It is quite fast when triggering from the trigger button, meanwhile, I tested the triggering thorough its wifi API, it was strangely slower than the JPEG version.C currently we do recommend the JPEG version. With seagull problem is you do not get feedback from the camera, if camera skips one photo triggering you will have problems in geotagging
Matthew we usually do tests >70% overlap percentages, RX0 indeed supports 0.5fps with high-quality sd-cards
Comment by Tomi Piriyev on June 1, 2018 at 1:03am
Pascal P.Pascal if you are really interested in very high precision mapping  we can implement 
multi-pass surveying algorithm as well.
Example Scenario. 
Let's say you want to get 0.8cm/px resolution and you have to trigger in 0.7sec intervals
with multi-pass scan dronee plane will pass 3 times the same path
to trigger in the midpoints (each time +0.7sec intervals) that it skipped in the previous passes.
Thus, if the plane has the maximum flight time of 60min with the full battery, you will cover the area of 20min flight time.
Even with this, you probably will be able to cover  more area than you do with the multirotor by benefiting
