Hi everyone,

I'm using Senz3d to get depthimage data, and I would like to use this depthimage data with package depthimage_to_laserscan. But when I run this data with depthimage_to_laserscan package, it showed the warning message below:

[ WARN] [1407311794.272714061]: [image_transport] Topics '/softkinetic_camera/depth_registered/image' and '/softkinetic_camera/depth_registered/camera_info' do not appear to be synchronized. In the last 10s: Image messages received: 33 CameraInfo messages received: 0 Synchronized pairs: 0

I think I have to publish '/softkinetic_camera/depth_registered/camera_info', but I don't have any experienced with this. So, anyone can help me?

Thanks, Duong

It looks like your camera driver isn't publishing CameraInfo messages for the depth image properly.

The driver probably needs to be updated to support maintaining and publishing CameraInfo. The camera_info_manager library makes this easier.

Hi ahendrix,

Thank for your answer. Do you have any guides or tutorials to work with camera_info_manager and CameraInfo ?

Comment by ahendrix on 2014-08-07:
Not really. The only tutorial available in the camera_info_manager package just links to the source code the camera1394 driver: http://wiki.ros.org/camera_info_manager/Tutorials/UsingCameraInfoManagerInCameraDriver%28C%2B%2B%29

Thank ahendrix, I'm trying to use camera_info_manager. I will post the solution when success.

Hi @ahendrix, do you have experienced with following error: Could not convert depth image to laserscan: scan_height ( 1 pixels) is too large for the image height.?
