srv / libfovis Goto Github PK

Quite some time passed since this fork got initialized and the upstream version has been updated since then.
The ROS wrapper might need an update after that, too.

I use processFrame() in VisualOdometry class to add image(left) and stereoSource which contain right image.But the matching status is always 4 which means large reproject error.

Is there any sample code for stereo camera fovis? I only see the depth camera sample code.

Hi,
The fovis_ros publishes at a very low frequency, 2-3hz. We have the same problem as srv/fovis#7

       Any suggestions? Thanks a lot!

Hi, I run $catkin_make for fovis, but it has the following errors, could someone provide some suggestions? Thanks in advance!

CMake Error at /opt/ros/hydro/share/catkin/cmake/catkinConfig.cmake:75 (find_package):
Could not find a configuration file for package libfovis.

Set libfovis_DIR to the directory containing a CMake configuration file for
libfovis. The file will have one of the following names:

libfovisConfig.cmake
libfovis-config.cmake

Sadly, there are no install targets defined in the CMakeLists.txt which results in a debian package ros-hydro-libfovis (I'm using hydro but here are no install targets for groovy and indigo either) that builds perfectly but does not install anything. This is what is installed after running sudo apt-get install ros-hydro-libfovis:

cdondrup@calculon:/opt/ros/hydro

This shows that a pkg-config file is created but it points to non-existing directories. This results in packages relying on libfovis to not build, like

-- +++ processing catkin package: 'fovis_ros'
-- ==> add_subdirectory(fovis/fovis_ros)

and makes it therefore useless as a debian package.

Are there any plans on adding install targets: http://wiki.ros.org/catkin/CMakeLists.txt (10. Optional Step: Specifying Installable Targets)? If there is no one actively working on this, I can also create install targets and open a pull request because I would really like to be able to use this.

The 32bit builds fails for a while on the build farm: http://jenkins.ros.org/view/IbinT32/job/ros-indigo-libfovis_binarydeb_trusty_i386/ The maintainer should have received emails for those.

In the upcoming sync the previous Debian packages will be removed from the apt repo if there is no new release being made which fixes the build: http://www.ros.org/debbuild/indigo.html?q=regression
