color_converter_sample.launch
-----------------------------

.. code-block:: bash

  roslaunch jsk_pcl_ros color_converter_sample.launch

color_filter_sample.launch
--------------------------

.. code-block:: bash

  roslaunch jsk_pcl_ros color_filter_sample.launch

pointcloud_screenpoint_sample.launch
------------------------------------

.. code-block:: bash

  roslaunch jsk_pcl_ros pointcloud_screenpoint_sample.launch



This script displays which point the user pointed on a 2D screen in the 3D rviz.

Sample images below:

.. image:: launch/images/pointcloud_screenpoint_3people.png
  :width: 640

There are two parameters to input.

1. 'image' is used in showing a image view on the image_view2, and its camera_info parameter is used for changing the coordinates of points.
2. 'points' is the pointcloud source to estimate 3D points that the user wantedt to specify on a 2D screen.

For example,
By default, pointcloud_screenpoint takes camera image and point clouds from kinect.

.. code-block:: bash

  roslaunch jsk_pcl_ros pointcloud_screenpoint_sample.launch

You can mix wide_stereo camera and assembled_tilt_scan.

.. code-block:: bash

  roslaunch jsk_pcl_ros pointcloud_screenpoint_sample.launch image:=/wide_stereo/left points:=/tilt_laser_cloud2

Or, you can mix kinect camera and assembled_tilt_scan.

.. code-block:: bash

  roslaunch jsk_pcl_ros pointcloud_screenpoint_sample.launch image:=/camera/rgb points:=/tilt_laser_cloud2
