arg 'serial_stereo' is not defined. #54

I'm using ensenso N30-802-16-IR stereo 3D camera. For the launch file, I don't know the number of Serial of the Ensenso stereo camera and Serial of a mono camera supported by the NxLib. How to find this two number?

The serial number is printed on a label on the device. You can also see it in NxView, when you open the camera there. See this topic in the manual for more information on how to set up your camera.

Yes. I know how to get serial number of this camera. For exanple, in the nodelet.launch file, when I use the "", I change the value to my camera's serial number. But when I want to use "color_point_cloud.launch", I also need to change the value of

When I change both value into my serial number, the launch file is not work. It will show: RLException: arg 'serial_stereo' is not defined. Arg xml is The traceback for the exception was written to the log file So what should I do?

Unfortunately I don't really understand the problem. The message RLException: arg 'serial_stereo' is not defined. is a ROS error message. Did you define this parameter when starting the launch file? Note that in color_point_cloud.launch there is currently no value for the serial_stereo argument. You have to specify it on the command line or when including it in another launch file. Alternatively you can modify the launch file and add value="<YOUR SERIAL>".

For using this launch file, you should also have a color camera in addition to your stereo camera. It sounds like you only have a stereo camera.

So I looked at the tutorial. There is no existing code to visualize depth images. Am I right?

What exactly are you searching? You can visualize all the data from this node in RViz.
