issue viewing multicameras from rviz or image_view about pointgrey_camera_driver HOT 7 CLOSED

I still have this problem with two GigE PGE cameras. I get this error when some node demands images from the second camera:

[ERROR] [1419250192.411562627]: PointGreyCamera::grabImage Failed to retrieve buffer | FlyCapture2::ErrorType 41There is an image consistency issue with this image.

@konradb3 @ecuzzillo Do you guys know anything about this?

Potentially related: #28 #27 (comment)

Not at all. The only thing I would note is that the 'There is an image consistency issue with this image." spams quite regularly in normal operation. I imagine there is some crazy bug with reusing memory when it's not supposed to, but I have no good idea for where it would be.

I have reinstalled the ros-package and checked the version of libflycapture2. I still have the same issues. In the video I run a launch file with two nodelet-managers (one per camera).

Hi Patrick,

I use your launch file #8 (comment) for two flea3 cameras. But only the first camera is streaming, although i got topics from both left_camera and right_camera. I have already follow the instruction of usbfs setting. Do you have a clue of what might be wrong?

many thanks

Hello,
I am trying to use two Pointgrey cameras, and also have this problem:
[ERROR] [1446217164.145882434]: PointGreyCamera::grabImage Failed to retrieve buffer | FlyCapture2::ErrorType 41There is an image consistency issue with this image.

The cameras are connected, and I can see the topic for both, but once I want to see the stream from them, using image_view, the error occurs for image_raw topic. And to compare for image_mono, the window just opens but no stream is visible (white window) and no error message is sent.
I tried increasing memory buffer, I followed the solutions from ROS Wiki but it doesn't help - still the same error.
The funny thing is, that my friend is using exactly the same launch file on his computer and the same version of driver and ROS, and it works for him strangely: he can see the stream but once in a few seconds he receives the same error message, but the stream doesn't stop.
Can anyone help with that? I would really appreciate it
