Hello
#1 Sorry, I didn´t want say a wonderful Geotagging photos. I wanted to say that in the Datalogging excell file could be show one field with the moment at the camera shutter servo is "On" "value=1". The GPS time to link the shutter instant can be quantized (like MIDI music, here 1/4 second) to the first record after the On is enabled. So you have the airplane position when the camera is triggered. Very cool!
#2 May be it is crazy and so difficult development, I think not very useful but here I go... Due to changes on the terrain height surface we must use a safety height to avoid the hills but, I don´t know if the Gluponpilot height is computed from the take-off position by pressure or by the GPS, anyway, but ussing a Digital Terrain Model Elevation take from contour lines in Google Earth is an updated, So tha plane height is fixed to the real terrain. The problem is the memory to store the data. A raster file from 30x30 m grid, I don´t know
.
#3 Like you stabilize the camera in roll or pitch angles . I think to hang the camera from a servo that lies in the yaw axis. The servo could correct the drift in the heading of the plane to real or computed azimuth, direction between previous and next waypoint in a flight line. So the photos are always parallels and lies in the computed direction from Ground Control Station avoiding the effects of the real flight, like a crab moves (as we say in Spain). A damping pivot uses the gravity force to correct the roll and pitch. In straight line. I suppose an angular pitch and roll not over to 10º, It is 2 cm or less in the camera lenses border. This only to use in not windy days.
i don´t want weary to you with my ideas, I will keep them for another day and a real test with the board.
I have read all Gluonpilot wiki. Next days more forum post but I think the commands in navigation editor and the option to test the flight before to do it are really really cool. Congratulations, enhorabuena
