I put my target_link_libraries (pose_sensor boost_system) after my target_link_libraries(pose_sensor ssf_core) and for apt-get install libboost-all-dev the results I get is 0 upgraded, 0 newly installed, 0 to remove and 29 not upgraded. Still get error haha..

Yeah..So what I did is put that line after rosbuild_add_executable(pose_sensor src/main.cpp src/pose_sensor.cpp). And..the results is the same. Any other idea..Thanks!

Hi, I've put it the line under my "target_link_libraries(pose_sensor ssf_core)", but still I'm generating the error. Any other solution, thanks!

Hi guys, I've been getting this error lately every time I compile my ethzasl_sensor_fusion.

The error I received is below:

Can you guys help me out with this problem. Thanks!!

Hi guys,

Does anyone of you know how to perform a decentralized cooperative slam for multi uav. Like the one in sFly project. I just want to know what kind of software they used. Thanks, really appreciate for any replies!!

I'll take a look at it, thanks!

Okay thanks for the information. Another question I want to ask is how you get the information regarding the "Header"?

Hi guys,

I am doing this robot simulation on the UDK/UsarSim and have been able to publish image from the Robot Camera in the simulator to the ROS System. Then I want to use this image to perform SLAM using the V-Slam from willow garage. The problem is that the V-Slam node also subscribe to the CameraInfo Message. So my question is how to obtain the Camera Info Message from the USARSim/UDK?

Thanks

Hi guys,

Do anyone of you know how to reconstruct scene model/area from the information obtained from PTAM (using point cloud maybe) or any visual slam algo like RGBD SLAM or V-Slam.

Thanks

Ok man, thanks for the link! :) I try mine using python btw

Hi guys, I have this python code that is able to save an image on my hardrive in JPEG format. The question I want to ask if any of you guys know how to publish this image as a sensor_msg/image in ROS. Thanks

Haven't yet. Up until now, I still don't know how to debug the ROS Gazebo.

On the UDK/USARSim, there's this dedicated port for image stream from a camera in a simulation. It uses the UDK's Image Server. Does anybody know how to obtain the image from the UDK Image Server using any package available in ROS? Btw the UDK is located in a different computer. Thanks.

Hi, just wanna ask, is it possible two have more than 2 ROS system on one Ubuntu system? Example Ubuntu will both have fuerte and electric.
