[ERROR] /camera/driver - No cameras detected!

[SMish7]

Hi,

When I try to run the camera node by typing roslaunch realsense_camera lr200m_nodelet_default.launch , I get the following output..

...

[ INFO] [1500396825.912293125]: Initializing nodelet with 4 worker threads.

Why is it so? Can't I run the camera without using the web interface?

Hi SubMarIn,

the above command "roslaunch realsense_camera lr200m_nodelet_default.launch" is the correct command and should work.

Can you please check if there is any running scenario that locks camera ?

Thanks,

No, there is no running scenario.

Hi SubMarIn,

So when you start Euclid 'Cameras' scenario all runs fine, and only when you do roslaunch it fails ?

Basically you can see from the web api if you go under 'Euclid Nodes' -> Edit 'Cameras' node the exact launch file used.

it should be the same as the one you launch manually.

I am having the same issue as above. I don't know what happened but I am no longer able to launch lr200m_nodelet_default.launch. It said the package and file could not be found so I downloaded realsense_camera from github and followed the installation instructions. After I finished, I get the error above when I launch the file. If I try to run the camera scenario, it says it works, but when I go to the monitors, I cannot see any images. I would love some help with this.

Some more background: I have the realsense_camera package and launch file in the euclid_ws. I thought I already had the realsense_camera package in /opt/ros/kinetic/share/realsense_camera but it does not have the lr200m launch file in it. It has all of the different camera type launch files like zr300_nodelet_default.launch and r200_nodelet_default.launch.

Hi,

For ROS, you need to have the Euclid version. it is in herehttps://github.com/IntelEuclid/realsense_camera https://github.com/IntelEuclid/realsense_camera

https://github.com/IntelEuclid/realsense_camera GitHub - IntelEuclid/realsense_camera: Intel Euclid RealSense camera for Intel Euclid.

Try also to run the binaries - cpp_capture for example. (just type the command in a terminal)

Thanks,

Amit
