How I can run contour_moments.cpp OpenCV example?
I don’t know how to run the file contour_moments.cpp that’s able in this github link: https://github.com/ros-perception/vis...
I’m working with Indigo and I have installed OpenCV3 following this ROS.org link: http://wiki.ros.org/vision_opencv
when i run the command rosrun opencv_apps contour_moments
it only appear a warning and nothing else:
[ WARN] [1450293289.992148166]: Topic 'image' has not been remapped! Typical command-line usage:
$ rosrun image_rotate image_rotate image:=<image topic> [transport]
which topic should I use?? (I'm using a kinect, and it is working fine)
paste the errors here then
The required target_link_libraries are listed in the CMakeLists.txt file in the repository.
It might be easier to start with the entire vision_opencv package and progressively remove things from it until it is only building
contour_moments. Don't use OpenCV 3 unless you really need it instead of 2.4, building with it has some issues.Ok, so I have to uninstall OpenCV3 before installing Opencv2? .. If so, how do I do that?
OpenCV 2 is probably already installed in parallel if you have cv_bridge installed. If you have OpenCV 3 from debian/ubuntu packages
sudo apt-get remove ros-indigo-opencv3ok, now when i run the command
rosrun opencv_apps contour_momentsit only appear a warning and nothing else ...
