realsense_ros_camera

This package provides a ROS node for using the Intel® RealSense™ R200, LR200, and ZR300 cameras.

Features

  • Color RGB stream, up to 1920x1080 resolution
  • Depth 16bit stream, up to 640x480 resolution
  • Fisheye 8bit monochromotic stream, up to 640x480 resolution (ZR300 only)
  • IMU accel and gyro data streams (ZR300 only)

Firmware

To ensure you camera has the most current, supported firmware, please review the librealsense compatible device information. If the camera requires a firmware upgrade, please refer to the Intel® RealSense™ Camera software support page. Note: Currently there is no native Linux tool for FW updates; all updates require a system with Microsoft Windows.

Supported Camera Types

Intel RealSense R200 Intel RealSense LR200 Intel RealSense ZR300

ROS API

realsense_ros_camera

The Intel RealSense camera driver nodelet

Parameters

~serial_no (string, default: blank)
	Specify the serial_no to uniquely connect to a camera, especially if multiple cameras are detected by the nodelet. You may get the serial_no from the info stream by launching the camear.launch file.
~enable_depth (bool, default: true) 
	Specify if to enable or not the depth camera.
~depth_width (int, default: 480)
	Specify the depth camera width resolution.
~depth_height (int, default: 360)
	Specify the depth camera height resolution.
~depth_fps (int, default: 30)
	Specify the depth camera FPS.
~enable_color (bool, default: true)
	Specify if to enable or not the color camera.
~color_width (int, default: 640)
	Specify the color camera width resolution.
~color_height (int, default: 480)
	Specify the color camera height resolution.
~color_fps (int, default: 30)
	Specify the color camera FPS.
~enable_fisheye (bool, default: true)
	(ZR300 only) Specify if to enable or not the fisheye camera.
~fisheye_width (int, default: 640)
	(ZR300 only) Specify the fisheye camera width resolution.
~fisheye_height (int, default: 480)
	(ZR300 only) Specify the fisheye camera height resolution.
~fisheye_fps (int, default: 30)
	(ZR300 only) Specify the fisheye camera FPS.

Usage

To start the camera:

$ roslaunch realsense_ros_camera camera.launch

To start the camera and camera viewers to see the video stream:

# For R200/LR200 camera:
$ roslaunch realsense_ros_camera demo_r200_camera.launch
# For ZRZ300 camera:
$ roslaunch realsense_ros_camera demo_zr300_camera.launch

Differences between this node and realsense_camera

A full featured realsense camera node is available as open source at http://github.com/intel-ros/realsense. This camera node is intended to be a smaller and more compact node illustrating use of the included middleware.

  • This node is provided as sample source code only, and is not available pre-built as a ROS package.
  • This node only supports the R200, LR200, and ZR300 cameras
  • This node does not support use with a RGBD launch script
  • This node does not support dynamic configuration of camera parameters
  • This node does not export use of IR streams from camera
