Hi everyone,
I have some problem to understand how to convert images with cvbridge. I red the tutorial : http://wiki.ros.org/cv_bridge/Tutoria... .

But I can't find a way to convert a openCV images to ROS images message. I succed to convert from ROS to openCV. I wanted to use the function toImageMsg() but it returns a sensor_msgs::Image but I want a sensor_msgs::ImageConstPtr.
Can somebody help me please?
Thank you.

I add the dependecies and it worked once and now it doen't work anymore...

I use the code on github. i didn' modify it. I was jsut trying to migrate it to catkin

If I delete the folder, they are built again and I hav the same error. I use this https://github.com/procrob/procrob_functional/tree/master/face_recognition

I have the same error

When you use the FaceRecognition.action did it automatically generate the FRClientgoal? because in my case it did'nt and I copy and plaste the old one. Maybe that's why it's not working.

Hi everyone, I am trying to move the face recognition package to catkin. Itried with http://wiki.ros.org/catkin/migrating_... but it doesn't work. So I create a new catkin workspace and I tried to add every folder one by one as if it was a new project. When I try to do a catkin_make I have this message :

ERROR: invalid message type: face_recognition/FRClientGoal.
If this is a valid message type, perhaps you need to type 'rosmake face_recognition'

I tried to do a rosmake but I still have this error. My Cmakelist.txt is like this:

I already had some poblems that I tried to manage, see http://answers.ros.org/question/18798... but I seams that it still doesn't work. Can somebody help me please? thank you

Finaly I moved the executable in the right folder mnually but the program doen't understand the message FRclientGoal. what should I do ? Thanks for your help

I add manually FRClientGoal.msg in the Cmakefile. it generatage a FRClientGoal.h file. I can compile the project but when I try to make a rosrun, I have a message that says that the executables are not found. They are in the folder /ros/devel/lib/face_recognition and it looks only in the package folder src/face_recognition. How can I tell him to look in another folder?

FRClientGoal.msg should be generate from an action like all the other headers but it's not. that's the problem

I am back to my first error:
Linking CXX executable /home/www/ros/devel/lib/face_recognition/Fserver

I think I am in an infinite loop

I add to my CMakeLists.txt : add_dependencies(Fserver ${face_recognition_EXPORTED_TARGETS}) add_dependencies(Fclient ${face_recognition_EXPORTED_TARGETS}) Now I have this error: face_recognition.cpp:(.text._ZN3ros13serialization16VectorSerializerIfSaIfEvE5writeINS0_7OStreamEEEvRT_RKSt6vectorIfS2_E[void ros::serialization::VectorSerializer<float, std::allocator<float="">, void>::write<ros::serialization::ostream>(ros::serialization::OStream&, std::vector<float, std::allocator<float=""> > const&)]+0xae): undefined reference to `ros::serialization::throwStreamOverrun()' collect2: ld a retourné 1 code d'état d'exécution

When I try that, I still have the error about my FaceRecognitionAction.h that doesn't exist. I don't understand why it wasn't auto genrated.

I think it's the FaceRecognitionaction.h auto created from my action that also generate messages. I clean the message folder so the message can be built automatically and try to buil again but I still have the error about the FaceRecognitionaction.h missing. My folder devel/include is empty.

The error message says that the file FaceRecognitionAction.h doesn't exist but actually it exists and it's in my include folder. I don't know where I should put it so the program can find it. In the include file, I put all my headers. I don't know where else should I put them.

Yes that's what I am trying to do. I just did a catkin_make, the generation is done automatically.

I rename my action as FaceReco.action and it worked. but now I have a message : /home/www/ros/src/face_recognition/src/face_rec_client.cpp:12:52: fatal error: face_recognition/FaceRecognitionAction.h : Any file or folder of this type. I try to include a .h that I put in the folder include but I guess that's not where I should put it?

Hi, I got face recognition tutorial on ros wiki page:

www.ros.org/wiki/face_recognition

but i can't build it. I tried to build the workspace using catkin_make and rosmake. I use the command "catkin-make" in the face_recognition workaspace but it already contains a CMakeLists.txt so the command doesn't work. I also tried the "rosmake face_recognition" but I have this error "ERROR: No arguments could be parsed into valid package or stack names." despite the fact that there is a "stack.xml" file in the folder.

Can somebody help me please? Thank you

Hi everybody,

I am trying to install gscam http://wiki.ros.org/gscam ans I have many problems . First, when I did the command rosrun gscam gscam I had the warning
"Camera calibration file .ros/camera_info/camera.yaml not found."
So I find a camera.yaml and add it. Now I have the warning
"[camera] does not match name ~ in file .ros/camera_info/camera.yaml"
I think I have to add the camera name in the file but I can't find it with lsusb. If someone knows how to find it, it will really help me.

And as it is only a warning, I think I still can run the command. I have something like :

and my webcam is turned on but when I tried to display it with "rosrun image_view image_view image:=/gscam/image_raw" a small blank window pops up, but without any picture or video from my camera.
So I did a "rostopic hz --window=1000 /gscam/image_raw" to see what is published, but there are no messages published by the node.

When I list the topic, I have all topics published by gscam .
/camera/camera_info
/camera/image_raw
/camera/image_raw/compressed
/camera/image_raw/compressed/parameter_descriptions
/camera/image_raw/compressed/parameter_updates
/camera/image_raw/compressedDepth
/camera/image_raw/compressedDepth/parameter_descriptions
/camera/image_raw/compressedDepth/parameter_updates
/camera/image_raw/theora
/camera/image_raw/theora/parameter_descriptions
/camera/image_raw/theora/parameter_updates
/rosout /rosout_agg

And "rosrun rqt_graph rqt_graph" shows me the /gscam_publisher node and the /image_view nodeb and they are not linked.

I don't know what to do. Can somedody help me please?
Thank you
