visensor-node

ROS interface to the Visual-Inertial Sensor developed by the Autonomous Systems Lab (ASL), ETH Zurich and Skybotix AG. This sensor provides fully time-synchronized and factory calibrated IMU- and stereo-camera datastreams. A detailed spec sheet of the sensor can be found here. The low-level driver for the VI-Sensor can be found here.

A detailed description on how the sensor can be used in ROS is found in the corresponding ROS-Wiki.

Installation

Check out the sensor library and this node to your catkin workspace:

cd your_catkin_workspace
git clone https://github.com/ethz-asl/visensor_node.git
git clone https://github.com/ethz-asl/libvisensor.git

Make sure that you installed all necessary ROS packages

sudo apt-get install libeigen3-dev libopencv-dev libboost-dev ros-indigo-cmake-modules

Adjust the packet name to your ros version.

Build the package using catkin_make
