Hi,

I am getting a weird error from rviz when trying to show Laser Scan:

Transform [sender=/kinectFRMI] For frame [/openi_depth_frame]: Frame [/openi_depth_frame] does not exist

It is the same frame why needing a tf ?

I am trying to get fake laser scan from the point cloud /camera/rgb/points. And I wrote the node inspired from pointcloud_to_laserscan.

The topic /camera/rgb/points is publishing normally.

Thank you,

Can you confirm that both your fixed frame and target frame are set to /openi_depth_frame (target frame could be set to fixed frame and it should work if the fixed frame is correct)? Also, double check for a misspelling since the default is openni_depth_frame if I recall correctly.

Is it working, i.e. do you get a display, when you handtype your frame as fixed frame, and you just worry about the message?

The error message would be OK as there is no tf, but rviz should display the data in that case.

Hi, I get a display in rviz for the point cloud, from the kinect. And rostopic echo /scan show that there is data in this topic ... the problem is when I try to show /scan in rviz I get the error ! PS : in my laserScan I specified the frame at /openi_depth_frame which exist in tf
