I want to start opencv with this tutorial but it doesn't work for me.
I created a new package then added the cpp file to the src folder then added this line: rosbuild_add_executable(pkg_test0_imgToCv src/pkg_test0_imgToCv.cpp) to the CMakeLists.txt file. I already added the dependencies to the manifest file. Then make.
When I run it nothing happens, I expect the highgui would appear. I can confirm that my camera(gscam) is streaming images. I can see that the topics listed are active but using echo on the image_topic and image_topic_2 prints out nothing. Using rxgraph, there are only the gstreamer_publisher node and image_converter node connected to rosout node. Did I miss something? How do I get this thing to work?
thanks
