[Paparazzi-devel] Reply to "Camera Target Coordinates (Felix Ruess)"

[Chris]

Hi.
I am so tired lately that i don't have even the time to fly for months.
Things are going to Hell here so i need to work on other areas also
(i just finished some remote controlled targets for pistol shooting)
Anyway you need to add this line
<message name="CAM_POINT"      period="1.05"/>
to the telemetry file
and this line to the module or airframe file
<define name="SHOW_CAM_COORDINATES"/>
Felix is right the code needs some cleanup because i was under pressure 
while writing it
but since then i have rewritten the files a long time ago and now i use 
a joystick (Saitec Aviator)
exclusively for the camera and flight plan control.
Felix you are correct the code assumes a flat ground otherwise
someone would have to write some code to read and send the SRTM data to 
the airplane
after an airborne request for the data.
in order to correctly calculate the coordinates but it is sufficient for 
amateur use.
Also the RC servos have a mediocre resolution and accuracy (in degrees)
so even a minimum servo step movement of the camera from 1000m
changes the field of view more than 50m.
Felix where you can set the field of view for the GCS?
Other than that the code works fine, i use it all the time.
I can happily send you the newer version as well as the newer antenna 
tracker software.
