I am sorry to disturb you, but I am really facing a problem I cannot resolve. There is no error while running the command: roslaunch c2tam_visualizer visualizer.launch, but after I ran this command, there is nothing in the windows /vslam/real_visualizer and CTAM:VirtualWorld, then I found that the node C2TAMtracking Subscriber two topics:/camera/rgb/image_rect_color and /camera/depth_registered/image, but I found that in my computer, the topic /camera/depth_registered/image publishes nothing, then I use the topic /camera/depth_registered/image_rect to replace it, however, there is still nothing in these to windows! I have tried many ways, and till now, I get nothing..... OHH, I forget that in my ros, there is no openni_node.launch file in my package openni_camera, so I use the launch file openni.launch which is located in the package openni_launch to replace it. And my ROS is fuerte. I really need your help, thank you!! Thank you very much!!

what camera do you use? my camera is Asus. And I have the same problem...

Adangge commented 7 years ago

@longlongagox my camera is asus xtion too! How about your camera_parameters.yaml file into c2tam_tracking/launch folder? I have not changed it! And when I run all nodes in a laptop, then the rosservice call c2tam_vslam/start failed, and in Tracking node there is a feedback info "startCB". How about you?

Adangge commented 7 years ago

@longlongagox Through rosservice info c2tam_vslam/start, I find the the type of the rosservice is c2tam/RunVslam, and it is running in tracking node. So I think if the rosservice is not working, then there is no info from the camera.
