[ WARN]: Wait for a new image to proceed

[willdzeng]

Hi,

I am a software engineer in Transcend Robotics.
I am trying to use ZED as our vision camera to do SLAM.

When I use algorithm like rtabmap_ros, zed_wapper_node keep sending warning of wait for new images.
With rivz showing the image, it also have this warning.
Is this happening because of computation power? or maybe the image pointer published being occupied by other program or something like that?

Thanks.

Hi,

You can safely ignore this.
This warning appears when the processing is faster than the framerate of the camera. It means that the SDK still doesn't have a new image to work with, so it waits for a few ms.

It is not a problem and this should be more a ROS_DEBUG than a warning. In a next update, it will probably be removed since it isn't so useful.

Cool, Yeah, it doesn't affect other programs to run also.
