Synchronization problem between image and camera info using apriltags #33

Open jcarballeira opened 6 years ago

Hi there,

I am trying to use apriltags_ros package with Kinect v2. Keep getting the same warning saying image and camera info are not synchroniized. I'm using libfreenect2 and ros kinetic.

[ WARN] [1516297878.437969359]: [image_transport] Topics '/kinect2/hd/image_color' and '/kinect2/hd/camera_info' do not appear to be synchronized. In the last 10s: Image messages received: 189 CameraInfo messages received: 189 Synchronized pairs: 0

Having a look at apriltag_detector.cpp it is not entering the image callback, I think thats at least the immediate problem but I don't understand why. Could use some help, thank you

I don't know your program, the cause of my problem is running the camera program and apriltag on different computers, after I run them on a same computer, problem solved, I think it's net's problem

Did you manage to find a solution to this issue?

I also got the same issue, and I'm running camera and apriltag in the same PC.
