hi all i have an ueye UI-1221-M camera and i am trying to use ueye_cam to drive it. i have installed the IDS driver and can use the driver to open the camera. when i use "roslaunch ueye_cam rgb8.launch" the erro comes as follow.

    process[nodelet_manager-1]: started with pid [2384]
    process[ueye_cam_nodelet-2]: started with pid [2385]

* It seems that missing lib file how to deal with the problem? any help is appriciate*

[Update] Hi, thanks for your reply I have re-cloned the code and the error didn't disappear:

And i find problems when i build the package"rosmake ueye_cam" The MAKE process is really fast , i think many of the file did not MAKE correctly...

@anqixu please help me with it

Your new run shows the correct nodelet type of ueye_cam/ueye_cam_nodelet rather than ueye_cam/include/ueye_cam_nodelet. Also, the default repo branch is for catkin, not rosmake. So either use catkin_make (groovy&up) or switch branch: git clone https://github.com/anqixu/ueye_cam.git --branch fuerte

anqixu ( 2013-11-09 04:41:35 -0600 )edit

hi anqixu thanks i am useing the groovy but i can't config the catkin_make (i'm new here), so i downloaded the fuerte code and it works with my ueye.

vippt ( 2013-11-10 19:05:16 -0600 )edit

Hi anqixu. I'm using ROS hydro, compiling the package with catkin_make, but I still have the same problem: [ERROR] [1389397299.178431342]: Failed to load nodelet [/ueye_cam_nodelet] of type [ueye_cam/ueye_cam_nodelet]: Could not find library corresponding to plugin ueye_cam/ueye_cam_nodelet. Make sure the plugin description XML file has the correct name of the library and that the library actually exists. ------ The library exist and it is in the right path. How can I solve this problem?

Vero ( 2014-01-10 11:56:48 -0600 )edit

@Vero: hmm that's very weird. try checking out the fuerte branch and compiling (with rosbuild). Please also confirm that under the path [catkin_ws]/devel/lib, you have the files libueye_cam_nodelet.so libueye_wrapper.so

anqixu ( 2014-01-11 05:37:34 -0600 )edit

The package ueye_came-fuerte compiles and runs. The hydro version still has a problem. I can confirm that under the path [catkin_ws]/devel/lib there are the files libueye_cam_nodelet.so libueye_wrapper.so

Vero ( 2014-01-11 22:41:39 -0600 )edit

Since the libraries exist but are not getting found we need some more information to narrow it down. Can you please add the output of the following commands from the shell where your roslaunch invocation failed to your question? "rospack plugins --attrib=plugin nodelet | grep ueye" and "env | grep CMAKE_PREFIX_PATH" and "".

Dirk Thomas ( 2014-01-12 05:44:12 -0600 )edit

Since your CMAKE_PREFIX_PATH does not contain the path of your workspace it looks like that you have not sourced the workspace/devel/setup.bash file. Can you make sure to do that and try again?

I solve the problem. It was a problem of the id of the cameras. I used the master_slaves_rgb8.launch and I modified the id name.

Hi I basically have the same problem

I am using a UI 1221LE camera from a raspberry pi running minibian with ROS indigo. The camera is confirmed to be working from a ubuntu environment but have problems starting it from the minibian.

I have installed the arm 7 drivers and started successfully the daemon. I have tried to use the ueye_cam from apt-get, everything was ok but could not launch. Now i have cloned the git, compiled with catkin successfully, but when trying to run roslaunch ueye_cam rgb8.launch

i get the output

/root/ueye/ueye_cam/catkin_ws/devel/lib/ueye_cam/check_ueye_api: error while loading shared libraries: libueye_api.so: cannot open shared object file: No such file or directory=REQUIRED process [check_ueye_api-1] has died! process has died [pid 7478, exit code 127, cmd /root/ueye/ueye_cam/catkin_ws/devel/lib/ueye_cam/check_ueye_api __name:=check_ueye_api __log:=/root/.ros/log/2823c8ee-1392-11e7-a344-b827eba280a7/check_ueye_api-1.log]. log file: /root/.ros/log/2823c8ee-1392-11e7-a344-b827eba280a7/check_ueye_api-1*.log Initiating shutdown!

I confirm to have sourced catkin_ws/devel/setup.bash also, i confirm that the directory /devel/lib includes the files libueye_cam_nodelet.so and libueye_wrapper.so and they are not empty.

Moreover, Having commented the line

node name="check_ueye_api" pkg="ueye_cam" type="check_ueye_api" required="true" /

in src/launch/rg8.launch. i get a different error:

[ERROR] [1490697836.989684294]: Failed to load nodelet [/ueye_cam_nodelet] of type [ueye_cam/ueye_cam_nodelet] even after refreshing the cache: Failed to load library /root/ueye/ueye_cam/catkin_ws/devel/lib//libueye_cam_nodelet.so.

** having followed this thread on the ros page, I get the same problem, but unable to fix.

Moreover. i tried also to compile the fuerte branch, but with no success.

Thank you!

So it turns out i was using the wrong camera driver. I was using the driver for arm7 architecture with soft float instead of the one with hard float. the correct driver works fine and the ros_ueye_cam works well.

I +1ed for your sharing valuable info, but your posts should have been posted as a separate question (and answer) so that people with the same issue/interest can find it easily in the future.

It appears that your launch file is incorrectly trying to load a nodelet of type "ueye_cam/include/ueye_cam_nodelet" and failing, since the actual nodelet is of the type "ueye_cam/ueye_cam_nodelet" (which has been compiled successfully on your machine, if you look at the rest of the printout).

Please try updating your code from the github repo and trying again.

See: https://github.com/anqixu/ueye_cam/blob/master/launch/rgb8.launch

Hello, the topic is quite the same.

I have 2 cameras (UI-1241-LE-C-HQ) and I want to use both of them for sterevision. I'm trying to use the ROS package ueye_cam (fuerte branch).

When I run:

roslauch ueye_cam master_slaves_rgb8.launch

I get this error:

any suggestion? maybe @anqixu can help me.

thank you!

master_slaves_rgb8.launch is a special launch file, designed for a hardware-triggered synchronized multi-camera setup. Please see the wiki for additional information if interested. For non-synchronized stereo, please modify rgb8.launch to duplicate 2 instances of cameras, with different IDs.
