Hello, i wrote a plugin model to simulate an omnidirectional camera (i.e. a
simple camera that looks at an hyperbolical mirror: it receives distorted
circular images on a 360deg HFOV and some nonlinear VFOV). It works fine, so i'd
like to contibute to the project, if you're interested of course.
Anyway i have a problem with an extension of the plugin i have still to write.
Before reading the following, please note that i'm using gazebo 0.5.3 and player
1.6.4 (due to many compiling/running problem that i solved only downgrading)
So: i have to manipulate the mirror images to create panoramic images, more
"readable" to the user. I thought to give the model two camera interfaces, each
one with its image size, data and so on, so the user could decide to see only
the mirror image, or the panoramic or both by the simulation control. I cannot
use a single interface like StereoHead for example, because the two images are
different in sizes, and i don't want to create an interface ad hoc (i'd rather
stick to an existing standard, than create new one).
Also, to minimize trouble probability, i made a great copy&paste-work from
existing code :) but the problem is that gazebo seems to consider only the
second iface created (code below). Looking at other models that use two ifaces,
i noticed that they use 2 DIFFERENT ifaces (SickLMS200 uses laser and fiducial,
SonyVID30 uses camera and ptz), so i wonder, is there any problem or
consideration to be aware of using two ifaces of the same type?
Of course, if you have any other or better idea to resolve the problem, you're
very welcome. Thanks for any help or suggestion.

code:
int OmniCam01::Init( WorldFile *file, WorldFileNode *node )
{
...
// OmniCamera mirror interface
assert(this->mirrorIface);
if (gz_camera_create(this->mirrorIface, this->world->gz_server, this->GetId(),
"OmniCam01-mirror", (int) this, (int) this->parent) !=0)
return -1;
// OmniCamera panoramic interface
assert(this->panIface);
if (gz_camera_create(this->panIface, this->world->gz_server, this->GetId(),
"OmniCam01-panoramic", (int) this, (int) this->parent) !=0)
return -1;
...
}
It does not give any error compiling or running, just ignores mirrorIface
