Removal of all ROS related stuff from the PCL

Work in progress

Issues

ROS conversions

3rd Party conversion

To make it safe to mix PCL and ROS library- and include- paths, the following changes have been made:

  • The namespaces sensor_msgs and std_msgs no longer exist. Use the pcl namespace
  • PointCloud2 -> PCLPointCloud2, Image -> PCLImage, PointField -> PCLPointField, Header -> PCLHeader
  • The include paths reflect the new conventions. i.e., #include <std_msgs/Header.h> -> #include <pcl/PCLHeader.h>
  • Conversion functions no longer reference ROS. toROSMsg -> toPCLPointCloud2, fromROSMsg -> fromPCLPointCloud2
  • Conversion functions are now located in the pcl namespace. #include <pcl/ros/conversions.h> -> #include <pcl/conversions.h>
  • USE_ROS is deprecated -- your code should operate as if USE_ROS were set to false. E.g., PCLHeader.stamp is always an unsigned long.

To help with the migration process, you can use the following interactive script to do all the replacements. Replace DIFF_CMD and EDIT_CMD with your favorite diff and editing tools, and run

./remove_ros_3rdparty.bash path/to/my/project

This will only modify files once you've explicitly accepted the diffs with "(y)". Til then, the proposed changes are stored in .tomerge files. To break out of this, simply Ctrl+C and run

find path/to/my/project -name "*.tomerge" | xargs rm

remove_ros_3rdparty.bash
