What Is This

This node finds the nearest plane from input pose and publish pose aligned to that plane.

Subscribing Topic

  • ~input_obj_cloud (sensor_msgs/PointCloud2)

    Object point cloud used for initialization.

  • ~input_bkgd_cloud (sensor_msgs/PointCloud2)

    Background point cloud used for initialization.

  • ~input_obj_pose (geometry_msgs/PoseStamped)

    Object pose used for initialization.

Note that ~input_obj_cloud, ~input_bkgd_cloud and ~input_obj_pose should be synchronized.

  • ~input_cloud (sensor_msgs/PointCloud2)

    Target point cloud.

  • ~input_pose (geometry_msgs/PoseStamped)

    Object pose used for updating motion displacement.

Note that ~input_cloud and ~input_pose shoule be synchronized.
