How to use in `VIORB <https://github.com/jingpang/LearnVIORB>`_
|
|||
|
|
=============================================================---
|
|||
|
|
|
|||
|
|
|
|||
|
|
If you wanna run VIORB with MYNT® EYE，please follow the steps:
|
|||
|
|
---------------------------------------------------------------
|
|||
|
|
|
|||
|
|
1. Download `MYNT-EYE-S-SDK <https://github.com/slightech/MYNT-EYE-S-SDK.git>`_ and install mynt_eye_ros_wrapper.
|
|||
|
|
2. Follow the normal procedure to install VIORB.
|
|||
|
|
3. Update camera parameters to ``<VIO>/config/config_mynteye.yaml``.
|
|||
|
|
4. Run mynt_eye_ros_wrapper and VIORB.
|
|||
|
|
|
|||
|
|
Install MYNT-EYE-VIORB-Sample.
|
|||
|
|
------------------------------
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
|
|||
|
|
git clone -b mynteye-s https://github.com/slightech/MYNT-EYE-VIORB-Sample.git
|
|||
|
|
cd MYNT-EYE-VIORB-Sample
|
|||
|
|
|
|||
|
|
``ROS_PACKAGE_PATH`` environment variable. Open ``.bashrc`` file and add at the end the following line. Replace ``PATH`` by the folder where you cloned ``MYNT-EYE-VIORB-Sample``:
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
|
|||
|
|
export ROS_PACKAGE_PATH=${ROS_PACKAGE_PATH}:PATH/Examples/ROS/ORB_VIO
|
|||
|
|
|
|||
|
|
Execute:
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
|
|||
|
|
cd MYNT-EYE-VIORB-Sample
|
|||
|
|
./build.sh
|
|||
|
|
|
|||
|
|
Get image calibration parameters
|
|||
|
|
----------------------------------
|
|||
|
|
|
|||
|
|
Assume that the left eye of the mynteye camera is used with IMU. Through the ``GetIntrinsics()`` and ``GetExtrinsics()`` function of the `MYNT-EYE-S-SDK <https://github.com/slightech/MYNT-EYE-S-SDK.git>`_ API, you can get the image calibration parameters of the currently open device:
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
|
|||
|
|
cd MYNT-EYE-S-SDK
|
|||
|
|
./samples/_output/bin/tutorials/get_img_params
|
|||
|
|
|
|||
|
|
After running the above type, pinhole's ``distortion_parameters`` and ``projection_parameters`` is obtained, and then update to ``<MYNT-EYE-VIORB-Sample>/config/mynteye.yaml``.
|
|||
|
|
|
|||
|
|
Run VIORB and mynt_eye_ros_wrapper
|
|||
|
|
--------------------------------------
|
|||
|
|
|
|||
|
|
.. code-block:: bash
|
|||
|
|
|
|||
|
|
roslaunch mynt_eye_ros_wrapper mynteye.launch
|
|||
|
|
roslaunch ORB_VIO testmynteye.launch
|
|||
|
|
|
|||
|
|
Finally, ``pyplotscripts`` can be used to visualize some results.
