[custom] Problem trying to run with rtabmap_odom

[khuechuong]

I'm using ROS noetic and was trying to get odometry for oak-d pro poe. First, I tried the stereo_inertial_node.launch in depthai_example and wrote another launch odom.launch.

odom.launch

<node type="rgbd_odometry" name="rgbd_odometry" pkg="rtabmap_odom">
        <remap from="/rgb/image"        to="/stereo_inertial_publisher/color/image"/>
        <remap from="/rgb/camera_info"  to="/stereo_inertial_publisher/color/camera_info"/>
        <remap from="/depth/image"      to="/stereo_inertial_publisher/stereo/depth"/>
        <param name="frame_id"      type="string"   value="oak-d_frame"/>
        <param name="initial_pose"  type="string"   value="0 0 0.636 0 0 0"/>
        <param name="publish_tf"    type="bool"     value="true"/>

        <rosparam param="wait_imu_to_init">False</rosparam>
        <rosparam param="approx_sync">True</rosparam>
        <rosparam param="approx_sync_max_interval">0.1</rosparam>        
    </node>

it worked as it suppose to; it gives odometry and the tf tree:

However, when I tried it with the ros driver, it didn't give any error message, when I echo /odom, nothing appears. The tree also didn't change. basically I didn't see the odom frame in tf tree.

I'm not sure what's going on. Any thoughts? Thanks!

Hi, is every topic connected properly when you run rqt_graph? Also, is this file working for you?
