I have pointcloud2 data related to my lidar_frame. I would like to transform the data to my base_frame to use them with my ICP Algorithm. I found a sample here: https://answers.ros.org/question/291735/pointcloud2-transform-cpython/ but this example seems to be related to ros1.
Somehow I can not find tf2_sensor_msgs.tf2_sensor_msgs which contains do_transform_cloud
Is there any other sample out there?
I don't know if it is too late but to anyone wondering how to do this, in this PR just they solved that for ros2 (https://github.com/ros2/geometry2/pull/507) So you need to upgrade your ros version to Iron. There you should be able to use and import it as
from tf2_sensor_msgs import do_transform_cloud
