When I launch my camera using:

roslaunch pointgrey_camera_driver camera.launch

it starts working and publishing all topics, very normal!

Then I launch my node that subscribe to /camera/image_raw and it works fine. But when I shut down my node and launch it again, it doesn't work! even though the topic is still published.


rostopic echo /camera/image_raw

doesn't give anything after that.

I noticed I get that error:

[ERROR] [1491313248.152009223]: PointGreyCamera::grabImage Failed to retrieve buffer | FlyCapture2::ErrorType 41 There is an image consistency issue with this image.

What's the issue?

I'm using:

Ubuntu 16.04

ROS kinetic

Camera Blackfly 0.9 MP Color GigE PoE (Sony ICX692)

Driver camera:

The image packets are getting dropped, might be due to bandwidth congestion. Try increasing the packet delay or decreasing the packet size. Have a look at these two:

Increase Packet Delay

Increase PC Buffer capacity
