Learning Robotics using Python - Second Edition

Creating a ROS package with OpenCV support

We can create a package called sample_opencv_pkg with the following dependencies: sensor_msgs, cv_bridge, rospy, and std_msgs. The sensor_msgs dependency defines ROS messages for commonly used sensors, including cameras and scanning-laser rangefinders. The cv_bridge dependency is the OpenCV interface of ROS.

The following command will create the ROS package with the aforementioned dependencies:

    $ catkin-create-pkg sample_opencv_pkg sensor_msgs cv_bridge  rospy std_msgs  

After creating the package, create a scripts folder inside the package; we will use it as a location in which to save the code that will be mentioned in the next section.
