Ros wrapper for the ZED Stereo Camera SDK

This sample is designed to work with the ZED stereo camera only and requires the ZED SDK. For more information: https://www.stereolabs.com

This sample is a wrapper for the ZED library in order to use the ZED Camera with ROS. You can publish Left+Depth or Left+Right images and camera info on the topics of your choice.

A set of parameters can be specified in the launch file. Two launch files are provided in the launch directory:

   - zed_depth.launch: publish left and depth images with their camera info.
   - zed_stereo.launch: publish left and right images with their camera info.

The zed_depth_stereo_wrapper is a catkin package made to run on ROS Indigo, and depends on the following ROS packages:

• roscpp
• rosconsole
• sensor_msgs
• opencv2
• cv_bridge
• image_transport

Place the package folder "zed_wrapper" in your catkin workspace source folder "~/catkin_ws/src"

Open a terminal :

$ cd ~/catkin_ws
$ catkin_make
$ source ./devel/setup.bash

Open a terminal :

$ roslaunch zed_wrapper zed_depth.launch

WARNING : to get the depth in meters (it's a requirement for ROS), the baseline has to be set manually to 0.12 using ZED Settings App
