I have Ros Electric and I use ubuntu 11.10 in a Hp Pavilion. I use Kinect. I would visualize a pcl without Rviz (because Rviz in my pc goes to crash and I don't know why). I have created one node that gets the pcl from this topic /camera/rgb/points and converts it to an Image. this is a part of my code:

pcl::toROSMsg (*cloud, image_); image_.header.frame_id = cloud->header.frame_id; pub.publish (image_);

In my main i write: pub = nh.advertise<sensor_msgs::image> ("topic_image", 1000);

Then I make and run my node and in a new terminal when I write: rosrun image_view image_view image:=/topic_image

I see only window without image, I don't see my pcl. Why??? I hope that someone can help me....thanks

Hello, I hope you can help me.I have a problem with kinect. I open a terminal and write "roscore" then I open a new terminal for lunch my kinect. I open a new terminal for a make and after I open a new terminal for run my ros node. The first time I always get my results, but if I want to repeat the acquisition kinect, because I want to redo the run of the node (because I made the changes), the kinect disconnects. When I try to restart it no longer connects and I have to restart the PC to make it work. I use ros electric in ubuntu 11.10. This is the message when the kinect disconnects: [camera_nodelet_manager-1] process has died [pid 2623, exit code -6].
