Pteryx UAV photo mapping from Krzysztof Bosak on Vimeo.
After completing testign campaign and delivering the first examples we haverushed to publish a short documentary.
Pteryx is an UAV designed for civilianuse, together with its mission-oriented autopilot.
Our focus is in reliableoperation and single button interface. basically you have to put UAV on the
rails, select missions with rotary knobs, hold takeoff button until the
autopilot completes propulsion test, pull the bungee lock.
Pteryx can lift800g compact digital SLR in roll-stabilised head, providing superior quality
photography unachievable by other means: Better flying precision than manned
crafts, inaudible electric propulsion, very few parts to break (only 2 control
surfaces, folding propeller).
Endurance up to 120min, parachute landing,protected propeller.
Possible takeoff from hand and manual piloting.
By law,limited to visual range (some 500m) what yields 1km x 1km map.
Comments
Please, a little bit of respect for the pigeons... their elders served well during the WWI; I guess during that time, they did not care about environmental protection and they were just happy with whatever information the pigeons could bring back to them lol
I am sure you are not aware of th real costs of maintaining a network of pigeon stations and their environmental impact... Low mission readiness... Instable flight... Prone to disappear in wild areas... Inability to fly 30 times in a row over a field with exactly 50m spacing...
Not for this particual missions. My bad.
Yes GE georeferencing is pitful - we see 5-40m off here or there. But taking 19km photostrip and asking for georeferenced points explodes costs, while all they wanted was DOCUMENTED AREA OVERVIEW.
120min flight time is on several lipos in parallel. Something like 3S 14+/-1 Ah .
Yes L/D is good for a platform with a pylon bu the autopilot used is designed for endurance, after many calculations it turned out that statistically we fly halfway between optimal and minimal sinkrate airspeed.
I totally disagree with that statement. UAVs are platforms for remote sensing observations and therefore georeference is a requirement! Unless we want to return to the early experiments in aerial photography of the 19th century... then we should use pigeons instead of UAVs. It would cost largely less money!
The motorway results are not georeferenced because this was for making and overview of works to be carried out.
They are not even orthogonal as we have used a prototype without stabilisation, but with extra batteries and 2 cameras. The camera that worked was in continuous shooting mode so the points should be remapped using timestamp, yet nobody took the effort.
The square map is orthogonal but again nobody cares about georeferencing.
Normally we have points from GPS and corresponding photos (roll (should be null on the head), pitch, course+heading estimate, time, lat, lon) that we can provide for processing software.
I havent finished GPS export but my logdecode makes approx photo placing in kml since the beginning.
Georeferencing can be done roughly by inserting and overlay into google earth. All depends on application.
The key idea is that UAV flew exactly where it was requested so the user just took a look at the soil and planned operations along the 18km long section accordingly.
BTW The first screenshot of motorway mission are on the webpage. I will make a movie of it.
It appears beides making autopilot, UAV and arranging photo stitching, we will serve as mission consultants and operators on polish teritory as nobody looks ready for business until everything is known, clear and simple.
Our next step will be simple UAV ATC services, national communication network backup and Global Lost&Found Database ;-)
