This is the launch setup, we've been using with the Insta360:

<launch>
  <arg name="camera_name" default="camera360" />
  <arg name="frame_id" default="$(arg camera_name)_center_link"/>
  <arg name="calibration_name" default="insta360"/>

  <node pkg="nodelet" type="nodelet"
    name="$(arg camera_name)_nodelet_manager" args="manager"
    output="screen"
    respawn="true"/>

  <node pkg="nodelet" type="nodelet"
    name="$(arg camera_name)_nodelet_loader" 
    args="load libuvc_camera/driver $(arg camera_name)_nodelet_manager" 
    output="screen"
    respawn="true">

    <!-- Parameters used to find the camera -->
    <param name="vendor" value="0x2e1a"/>
    <param name="product" value="0x1000"/>
    <param name="serial" value="0"/>
    <!-- If the above parameters aren't unique, choose the first match: -->
    <param name="index" value="0"/>

    <!-- Image size and type -->
    <param name="width" value="3008"/>
    <param name="height" value="1504"/>
    <!-- choose whichever uncompressed format the camera supports: -->
    <param name="video_mode" value="mjpeg"/> <!-- or yuyv/nv12/mjpeg -->
    <param name="frame_rate" value="30"/>
    <param name="pub_every_n_th_image" value="3"/>

    <param name="timestamp_method" value="start"/> <!-- start of frame -->
    <param name="camera_info_url" value=""/>

    <param name="brightness" value="100"/>

    <remap from ="/image_raw" to="/$(arg camera_name)/image_raw"/> -->
    <remap from ="/camera_info" to="/$(arg camera_name)/camera_info"/>
    <remap from ="/set_camera_info" to="/$(arg camera_name)/set_camera_info"/>    
  </node>   

</launch>

Thankyou@Stefan Kohlbrecher. Yes I tried what you suggested,but when I try to launch it I have got this as an output. " Unable to open camera calibration file [/home/bittu/.ros/camera_info/camera.yaml]" So can explain me how to get this file.

You normally obtain this by standard camera calibration. As such calibration is meaningless for the Insta360's dual fisheye output, you should be able to ignore this warning. Or is this a error that causes the driver to not come up correctly?

Thank you for the reply.Yes,I was able to ignore that and was successful in publishing the footage.

This launch file worked with which camera version? Insta360 nano, pro, pro2? Did work for 3D streaming?

Dear @Katta Nigam,

might I please ask how you got the Insta360 to be connected properly to Ubuntu?

For us, launching the above launch file throws the error: uvc_find_device: No such device (-4) Looking at dmesg upon connecting the camera, we get the error: [sdb] No Caching mode page found [sdb] Assuming drive cache: write through

Could you point us in the right direction?

@h66
We have used Insta 360 Air android device. And we have used http://wiki.ros.org/video_stream_opencv package.

Thanks for the blazing response, @Katta Nigam ! :) Unfortunately for us, the Insta360 is not even listed as a /dev/device .... it seems we are still missing something low-level that is crucial. Did you face this problem as well? Or did everything work cleanly from the get go?
