Hi,
Actually, loading the module cam_point should be enough to activate
the control of the camera and the CAM message (at least before the
latest improvements to the cam driver). With the settings cam.xml,
you can also select which waypoint to use as a target (in mode cam
target). The CAM message should contain the cam angles (pan, tilt)
and the coordinates of the target. This message is relayed by the
server to the GCS. In the menu of the GCS, click on your aircraft
name and active the cam footprint. This display is not perfect, in
particular the aperture is probably hard coded somewhere. But it
shows the point where the camera is pointing, the footprint of the
camera on the ground (flat earth), and the target point of the
mission.

Hi Luke,
the downlink of the coordinates of where the cam is looking
at was added by Chris Efstathiou. So I'm hoping he can provide
some details here...
By skimming over the code it looks like you need to
have SHOW_CAM_COORDINATES defined and add the CAM_POINT message
to your telemetry file.
But sadly I don't know of any feature to directly show that
point in the GCS...
The whole camera control (pan, tilt, directions, coordinates
you are looking at, etc..) could use some serious love in terms
of refactoring and documentation on the wiki.
Would be great if you (or anyone for that matter) could work
on this (hopefully together with Chris)..
While I haven't used that, it seems to me that camera control
and display it is also lacking some features (and proper
documentation of course!), like definition of the field of view
to display in the GCS, showing of the coordinates (assuming a
flat ground surface) and direction the camera is looking. What
is already there is probably of limited use if it is not
properly shown in the GCS or documented how to make it available
to other tools...
Cheers, Felix

Hello all,
I've gotten the camera gimbal/stabilization module working
almost perfectly,
except for one thing: I can't figure out how to downlink the
camera target
coordinates... I've been through the code, and see where
they are
calculated, and have the various "define" statements in
place in the
airframe configuration. Based on my understanding of the
code, when a
target it 'locked', the coordinates are written to a
user-defined waypoint,
correct? If so, is there a way to display those coordinates
as a widget, or
do I just have to pull up the 'move waypoint' dialog, and
pick them up from
there? I do have the X/Y location of the camera waypoint in
the telemetry,
but these don't seem to be affected by the 'lock' command,
and a proper
lat./long. output would be more useful in my particular
application.
Thanks!
