Point Cloud and Depth Image Processing Nodes in ROS2
With ROS1, it was possible to conveniently process point cloud and depth image in launch file.
For example, below is a point cloud filtering routine using pcl_ros
<node name="cloudify_manager"
pkg="nodelet" type="nodelet" args="manager" output="screen"/>
<node pkg="nodelet" type="nodelet"
name="cloudify_hand_depth_filter"
args="load pcl/PassThrough cloudify_manager">
<param name="filter_field_name" value="z" />
<param name="filter_limit_min" value="0.25" />
<param name="filter_limit_max" value="3.0" />
<param name="filter_limit_negative" value="False" />
<remap from="~input" to="$(arg hand_depth)/points"/>
<remap from="~output" to="$(arg hand_depth)/points_filtered"/>
</node>
Below is a depth image processing routine that converts depth image into point cloud using depth_image_proc
<node name="cloudify_frontleft_depth" pkg="nodelet" type="nodelet"
args="load depth_image_proc/point_cloud_xyz cloudify_manager --no-bond"
output="screen">
<remap from="camera_info" to="$(arg frontleft_depth)/camera_info"/> <!--$(arg camera_info_topic)"/> -->
<remap from="image_rect" to="$(arg frontleft_depth)/image"/>
<remap from="points" to="$(arg frontleft_depth)/points"/>
<param name="queue_size" value="10"/>
</node>
Is this functionality still available with ROS2? If not, how to do the above two things in ROS2? (i.e. Point cloud filtering, and convert depth image into point cloud)
Specifically, I am using ROS 2 Humble.
