Failed to run ROS node #12
Comments
First off, I have only tested the node on Ubuntu 16.04 so there could be something going on about that. |
@vik748 thank you for your prompt reply. |
@vik748 thanks for the hint. I actually just remembered that I forgot to add this to the description, I changed the try-catch block to actually output the exception and the result was this error:
I did find this issue here. But I'm not sure how to use this, since I'm not triggering the camera. Also the gdb bt is:
|
@mfehr we are in fact using a software trigger in our version. Have you added your camera serial number as the 'master' because that is how the camera is triggered? Also why is the initial sleep at 20 secs can you lower that to like 2. |
@mfehr did you have any luck with your issue? |
@shahvi I tried with a lower skip and I added the serial number in master, no luck. I'm probably configuring sth wrong. I ended up using this ROS node for now. But I might try again with this one, since the other one is quite heavy in terms of dependencies that we don't really need. Since this is probably a very specific issue with how I configure things, I will close this issue and reopen it if I end up trying again. Thanks a lot for your support. |
@mfehr Can I have some instructions on installing the package referenced in your comment as the README file doesn't seem very useful (or it could be me misunderstanding some of the concept in the README file). Many thanks. |
If I remember correctly it's mostly installing the Spinnaker sdk and then building the catkin package. It depends on some msgs from the pointgrey_camera_driver package so that should be present in the workspace or system as well. |
@mfehr thanks for your reply. I keep getting the following errors and I don't know how to solve it. -- ~~ traversing 2 packages in topological order:
Add the installation prefix of "image_exposure_msgs" to CMAKE_PREFIX_PATH -- Configuring incomplete, errors occurred! Many thanks. |
Hi,I also encountered this problem, and I use Ubuntu 16.04, So, how did you solve this problem? |
Can you try installing |
Hi
I was trying to install the driver and ROS node for a Blackfly S 0.4MP (Mono) USB 3 camera, but the ROS node keeps failing with an obscure error message:
Console output:
Exception:
I modified the try-catch statement in
capture.cpp
to actually output the exception and got this:I did find this issue here. But I'm not sure how to use this, since I'm not triggering the camera. I'm just using the default
test_params.yaml
file (with changing the ID of course).GDB backtrache:
spinview works:
The camera application that came with the driver
spinview
works fine and successfully displays the camera image.My System:
Ubuntu 18.04, ROS melodic, I installed the driver (followed the instructions in the README) and pulled current master from this repo.
I tried searching online and also ran gdb, but it's an error from inside the driver, not the ROS node itself.
Could you give me a hint how I can fix this issue?
