I have gone through the tutorials for finding the IP address and setting up the camera for my desktop. When I run one the launch files (streaming or prosilica).launch in the with the correct camera IP address I don't see an image topic produced. I only get

vision@ubuntu:~/catkin_ws$ rostopic list

/diagnostics

/prosilica_driver/parameter_descriptions

/prosilica_driver/parameter_updates

/rosout

/rosout_agg

I am expecting to see a /prosilica/image_raw but I never see it and I am not sure what I am missing. I am using Groovy

I have the same problem. I tried fixing it by adding self.listener.waitForTransform(parent, child, rospy.Time.now(), rospy.Duration(5.0)) before (off,rpy) = self.listener.lookupTransform(parent, child, rospy.Time(0)) but then I get this tf.Exception: Lookup would require extrapolation into the past

just had to change it to lower case mono8.

That is set manually with dynamic reconfigure as the driver has many different types of images it can return Right now it is set as MONO8 before it is published. I am using electric ros.

This is from grabbing my image from a focus robotics stereo cam then I use stereo bridge and get this

When I try and run image viewer I get the error in the title what is going wrong?

fixed with target_link_libraries(${PROJECT_NAME} netpbm)

um I was missing a { in one of my header files.

I am trying to use and external library foo.a and I was told by the manufacturer to add -lnetpbm as a switch to your final link. as I am getting Linking CXX executable bin/fr_cam /home/scott/focusrobotics/release_20120111/lib/libfrdev.a(FrImage.o): In function FrImage': /home/scott/focusrobotics/release_20120111/src/libfrdev/FrImage.cpp:226: undefined reference topm_openr'

how do I do what he suggests?

I am trying to write a node for the Focus Robotics fpga stereo cam. I copied the code from bumblebee2 package and modified it to take the stereo cam and publish to image messages and a stereo message. My problem is with the dynamic reconfigure. I copied the bumblebee2 config file and added some of my own. It autogenerates the header file but it is full of errors like the following

In file included from /home/scott/ARA_Stack/fr_cam/cfg/cpp/fr_cam/Fr_camConfig.h:50:0,

I can build the bumblebee package without any errors. What is going on?
