This ROS package contains a driver node that reads frames from an RTSP video stream (e.g., IP Camera) and publishes them out as sensor_msgs/Image ROS messages.

rtsp_ros_driver implements the ROS camera_info_manager interface. This means that the driver node can seamlessly handle camera calibration files. rtsp_ros_driver stores camera calibration files in the directory $ROS_HOME/camera_info/. Export the environment variable $ROS_HOME to point to your catkin_ws directory.

 export ROS_HOME=<path_to_your_catkin_ws>

You can launch the rtsp_ros_driver main node by running:

roslaunch rtsp_ros_driver rtsp_camera.launch <arguments>

Launches the main node of the package (i.e., rtsp_driver_node). Unlike the rtsp_driver_node node, this launch file allows us to specify hostname, username, password, and other parameters about the camera separately. These parameters will be combined into a standard URL format and sent to the rtsp_driver_node node.

None.

Identical to the rtsp_driver_node node (see below).

hostname    (string)
         Hostname or IP of the RTSP camera.

username    (string)
         Username for the RTSP camera.

password    (string)
         Password for the RTSP camera.

stream    (string)
         Name of the video stream published by the RTSP camera.

camera_name    (string, default: rtsp_camera)
         Namespace of the camera.

camera_frame    (string, default: rtsp_camera_link)
         Name of the camera reference frame.

image_raw_topic    (string, default: ~image_raw)
         Name of the output image topic.

camera_info_topic    (string, default: ~camera_info)
         Name of the output camera info topic.

port    (int, default: 554)
         Port of the RTSP camera.

Main node of the package, it is responsible for reading frames from the given RTSP video stream source and publishing them out as sensor_msgs/Image ROS messages.

None.

/<camera_name>/<image_raw_topic>    (sensor_msgs/Image)
         Raw image stream from the camera.

/<camera_name>/<camera_info_topic>    (sensor_msgs/CameraInfo)
         Camera metadata.

~rtsp_resource    (string)
         RTSP URL to the camera string.

~camera_name    (string, default: rtsp_camera)
         Namespace of the camera.

~camera_frame    (string, default: rtsp_camera_link)
         Name of the camera reference frame.

~image_raw_topic    (string, default: ~image_raw)
         Name of the output image topic.

~camera_info_topic    (string, default: ~camera_info)
         Name of the output camera info topic.
