how to get point cloud data from Kinect ROS

edit

what we are trying to do is to get point clouds from Kinect. Is there any way to do it by using python ??

You need to install the driver first.

Take a look at this package: Drivers

In your python subscribe to point cloud Topics.

#!/usr/bin/env python
import rospy
import pcl
from sensor_msgs.msg import PointCloud2
import sensor_msgs.point_cloud2 as pc2
import ros_numpy

def callback(data):
    print(data)
    # Enter your code here


rospy.init_node('listener', anonymous=True)
rospy.Subscriber("/<Your topic name>", PointCloud2, callback)
rospy.spin()
