2012-11-27 18:26:59 -0500 asked a question libg2o changes?

I'm having difficulty compiling my code against the latest package version of libg2o (ie ros-fuerte-libg2o). My code still works with the stable version of g2o available on openslam.org, and until the latest update used to work fine against the libg2o version too.

What version of g2o is currently packaged in ROS and is there a changelist somewhere?

2012-05-17 19:57:05 -0500 asked a question Submitting a collection of ROS mercurial/git/bzr repositories

Currently our lab has a rather primitive single repository indexed by ROS that holds a whole bunch of unrelated stacks. I'd like to split these out into individual repositories, yet still have them indexed together under our lab banner, as a number of other groups seem to have done.

It's not obvious to me how to do this outside of svn. Do I create an overarching repository that simply holds the .rosinstall file for the various other repositories, and submit the address of this repository and .rosinstall to ros-users? And will modifying the .rosinstall in future allow me to add new stacks?

Yes, apologies - it's the pre-patch version that works!

2011-11-23 12:27:55 -0500 answered a question getting video from canon vc-c50i camera and sensoray framegrabber

My problem was fixed by running: v4l2-ctl -s ntsc, the default setup was PAL hence the scrambling.

Patch 5250 works for me: I have an inverted SICK, set the 'inverted' parameter to true in sicktoolbox wrapper, my transform has 0 0 0 on roll/pitch/yaw.

File is here, Min angle is 1.5707, Max angle is -1.5707, increment is -0.01745

Try changing line 468 of kinect_detect.cpp from: std::string model_string = "svm_models/" + model_name + ".model"; to: std::string model_string = "../svm_models/" + model_name + ".model";

This fixed the segfaulting for me.

Try video/x-raw-yuv or put ffmpegcolorspace as the last parameter.

2011-04-14 01:12:30 -0500 asked a question getting video from canon vc-c50i camera and sensoray framegrabber

I'm trying to get the video stream from a canon vc-c50i camera which connects to a sensoray 311 framegrabber on a MobileRobots Guiabot. Have tried gscam with

GSCAM_CONFIG="v4l2src device=/dev/video0 ! ffmpegcolorspace ! video/x-raw-rgb ! identity name=ros"

but image is scrambled. What should the pipeline be for this camera type?
