[BUG] Cannot locate node of type [stereo_mimic_node] in package [depthai_examples]

[zippyzoo77]

Hello,

I am trying to get separate stereo camera feeds so that I can run various SLAM repositories that need the stereo in two different ros topics (one for left and one for right), and I saw the stereo_mimicer example, and thought that might be just the kind of node I need, but it doesn't seem to have all of the required files to make it work. (Other examples like the stereo inertial node work fine, they just don't have the outputs I need.) So I guess two questions here, first does that example do what I am looking for? Second, how do I fix the error I keep getting? It looks like the file is just missing? I just updated both the standalone depthai stuff and the depthai-ros, and I can't find the needed file in the git repository either.

error: ERROR: cannot launch node of type [depthai_examples/stereo_mimic_node]: Cannot locate node of type [stereo_mimic_node] in package [depthai_examples]. Make sure file exists in package path and permission is set to executable (chmod +x)

ros version: noetic ubuntu version: 20.04

code to reproduce: roslaunch depthai_examples stereo_mimicer.launch

Hi, first I'd like to clarify the desired outputs, do you want to output left and right sensor streams from the stereo node? If yes, this can be enabled in depthai_ros_driver using parameters.

The stereo_mimicer has been deprecated some time ago, although it seems that the launch file was missed for the deprecation in noetic branch, you can find the node code here.

Yes the sensor streams is what I am looking for, I was able to get them by modifying the code that makes the stereo inertial node, but I will keep the parameter method in mind for future uses. Thanks!

Glad I could help. Closing the issue, please reopen or make a new one if you have further questions.
