NVIDIA Jetson Xavier NX部署VINS-fusion-GPU

一、环境配置（Ubuntu 18.04）

1、Cuda 10.2的安装

sudo apt-get update
sudo apt-get install cuda-toolkit-10-2

安装好之后，在 .bashrc中配置环境变量。source之后，nvcc – version 即可查看cuda版本。

export PATH=/usr/local/cuda-10.2/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-10.2/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export CUDA_ROOT=/usr/local/cuda

2、Eigen（用ROS自带的也可以）

# Remove pre-built Eigen
 sudo apt-get remove libeigen3-dev 
cd ~/Downloads/
wget -O eigen.zip https://gitlab.com/libeigen/eigen/-/archive/3.3.7/eigen-3.3.7.zip #check version
unzip eigen.zip
mkdir eigen-build && cd eigen-build
cmake ../eigen-3.3.7/ && sudo make install
pkg-config --modversion eigen3 # Check Eigen Version

3、Ceres solver

cd ~/Downloads/
sudo apt-get install -y cmake libgoogle-glog-dev libatlas-base-dev libsuitesparse-dev
wget http://ceres-solver.org/ceres-solver-1.14.0.tar.gz
tar zxf ceres-solver-1.14.0.tar.gz
mkdir ceres-bin
mkdir solver && cd ceres-bin
cmake ../ceres-solver-1.14.0 -DEXPORT_BUILD_DIR=ON -DCMAKE_INSTALL_PREFIX="../solver" 
 
  #good for build without being root privileged and at wanted directory
  
make -j3 # 6 : number of cores
make install
bin/simple_bundle_adjuster ../ceres-solver-1.14.0/data/problem-16-22106-pre.txt # to check version

4、Opencv 安装

关于Opencv 的安装需要特别谨慎，不建议频繁删除以前的库，因为多个项目使用的版本可能不同，所以可以将常用的版本安装在/usr/local下，将其余版本安装在自己Download或者home下。
如果需要删除原来的版本，执行以下命令：

# remove prebuilt opencv
sudo apt-get purge libopencv* python-opencv 
sudo apt-get update
sudo apt-get install -y build-essential pkg-config
 
## libeigen3-dev # recommend to build from source
 
sudo apt-get install -y cmake libavcodec-dev libavformat-dev libavutil-dev \
    libglew-dev libgtk2.0-dev libgtk-3-dev libjpeg-dev libpng-dev libpostproc-dev \
    libswscale-dev libtbb-dev libtiff5-dev libv4l-dev libxvidcore-dev \
    libx264-dev qt5-default zlib1g-dev libgl1 libglvnd-dev pkg-config \
    libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev mesa-utils     
 
sudo apt-get install python2.7-dev python3-dev python-numpy python3-numpy

# To fix OpenGL related compilation problems 
 cd /usr/lib/aarch64-linux-gnu/
sudo ln -sf libGL.so.1.0.0 libGL.so
sudo vim /usr/local/cuda/include/cuda_gl_interop.h
 # Comment (line #62~68) of cuda_gl_interop.h 
 //#if defined(__arm__) || defined(__aarch64__)
//#ifndef GL_VERSION
//#error Please include the appropriate gl headers before including cuda_gl_interop.h
//#endif
//#else
 #include <GL/gl.h>
//#endif

安装新的版本（因为VINS-FUSION-GPU版本需要支持CUda的OpenCV，所以选择3.4.1版本）
Then once linking is done, go to Downloads to begin opencv installation

cd ~/Downloads/
wget -O opencv.zip https://github.com/opencv/opencv/archive/3.4.1.zip # check version
unzip opencv.zip
cd opencv-3.4.1/ && mkdir build && cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
        -D CMAKE_INSTALL_PREFIX=/usr/local \     #这里的/usr/local可以换成自己的安装路径，到时候在Cmakelist里设置自己设置的路径即可。
        -D WITH_CUDA=ON \
        -D CUDA_ARCH_BIN=7.2 \     #对于NX和AGX,选7.2，Nano，TX2选6.2 
        -D CUDA_ARCH_PTX="" \
        -D ENABLE_FAST_MATH=ON \
        -D CUDA_FAST_MATH=ON \
        -D WITH_CUBLAS=ON \
        -D WITH_LIBV4L=ON \
        -D WITH_GSTREAMER=ON \
        -D WITH_GSTREAMER_0_10=OFF \
        -D WITH_QT=ON \
        -D WITH_OPENGL=ON \
        -D CUDA_NVCC_FLAGS="--expt-relaxed-constexpr" \
        -D WITH_TBB=ON \
         ../
make  # running in single core is good to resolve the compilation issues         
sudo make install
cd ../../ && sudo rm -rf opencv-3.4.1 # optional (can save 10GB Disk Space)
pkg-config --modversion opencv # Check opencv Version

OpenCV 在NX上的安装比较慢，差不多需要1个小时。OpenCV安装好以后，需要进一步编译CV-Bridge( cv_bridge是在ROS图像消息和OpenCV图像之间进行转换的一个功能包)。

5、CV-Bridge的编译

CV-Bridge的安装需要下载对应的版本，由于NX 是基于Ubuntu 18.04的ARM系统,因此下载melodic版本的CV-Bridge。首先，通过以下连接进入下载页面：

https://github.com/ros-perception/vision_opencv

如图所示:
vins-fusion-gpu,ubuntu,linux,计算机视觉,动态规划,人工智能

# 选择下载melodic版本到catkin_ws/src目录下，
gedit vision_opencv/cv_bridge/CMakeLists.txt
# Edit OpenCV PATHS in CMakeLists and include cmake file
# /usr/local/share/OpenCV 选择自己安装的OpenCV对应路径
find_package(OpenCV 3 REQUIRED PATHS /usr/local/share/OpenCV NO_DEFAULT_PATH 
  COMPONENTS
    opencv_core
    opencv_imgproc
    opencv_imgcodecs
  CONFIG
)
include(/usr/local/share/OpenCV/OpenCVConfig.cmake)  #under catkin_python_setup()
# Save and close CMakeLists
#  Build the package
cd .. && catkin_make

二、Vins-Fusion GPU编译安装

1、Vins-Fusion GPU

cd ~/catkin_ws/src && git clone https://github.com/pjrambo/VINS-Fusion-gpu #GPU

sudo apt-get install ros-melodic-tf
sudo apt-get install ros-melodic-image-transport
sudo apt-get install ros-melodic-rviz

# Edit CMakeLists.txt for loop_fusion and vins_estimator
cd ~/catkin_ws/src/VINS-Fusion-gpu/loop_fusion && gedit CMakeLists.txt

##For loop_fusion : line 19
#find_package(OpenCV)
# /usr/local/share/OpenCV/ OpenCVConfig.cmake 选择自己安装的OpenCV对应路径
include(/usr/local/share/OpenCV/OpenCVConfig.cmake)

cd ~/catkin_ws/src/VINS-Fusion-gpu/vins_estimator && gedit CMakeLists.txt

##For vins_estimator : line 20
#find_package(OpenCV REQUIRED)
# /usr/local/share/OpenCV/ OpenCVConfig.cmake 选择自己安装的OpenCV对应路径
include(/usr/local/share/OpenCV/OpenCVConfig.cmake)

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

2、数据测试。

2.1公开数据集测试【以EuRoC（Stereo cameras + IMU）为例】

 roslaunch vins vins_rviz.launch
    rosrun vins vins_node ~/catkin_ws/src/VINS-Fusion/config/euroc/euroc_stereo_imu_config.yaml 
    (optional) rosrun loop_fusion loop_fusion_node ~/catkin_ws/src/VINS-Fusion/config/euroc/euroc_stereo_imu_config.yaml 
rosbag play YOUR_DATASET_FOLDER/MH_01_easy.bag

数据可以通过一下链接下载到：

2.2 测试自己的设备（D435i+阿木P450）

在配置参数文件中加入以下参数，使得GPU起作用
vins-fusion-gpu,ubuntu,linux,计算机视觉,动态规划,人工智能

In the config file, there are two parameters for gpu acceleration.
use_gpu: 0 for off, 1 for on
use_gpu_acc_flow: 0 for off, 1 for on
If your GPU resources is limitted or you want to use GPU for other computaion. You can set
use_gpu: 1
use_gpu_acc_flow: 0
If your other application do not require much GPU resources, I recommanded you to set
use_gpu: 1
use_gpu_acc_flow: 1

IMU和相机外参标定可以通过VINS实时在线标定或者使用Kalibr工具包进行标定，相关资料比多了，不再赘述。

下期给各位铁子们汇报在阿木实验室P450上部署VINS+Prometheus+Ggo-Planner的工作。
