• Camera frame rate
  • lower - low time delay, poor performance
  • higher - high time delay, better performance
  • has to be set from camera launch file: 10~30hz
• Max tracking Feature number max_cnt
  • 100~150, same correlation as camera frame rates
• time offset between IMU and cameras estimated_td: 1, td : value from kalibr
• GPU acceleration use_gpu: 1, use_gpu_acc_flow: 1 (for GPU version)
• Threads enabling - multiple_thread: 1

• Eigen latest Stable version below new home or old home

$ wget -O eigen.zip https://gitlab.com/libeigen/eigen/-/archive/3.3.7/eigen-3.3.7.zip #check version
$ unzip eigen.zip
$ cd eigen-3.3.7
& mkdir build && cd build
$ cmake .. && sudo make install

• Eigen 3.3.90 version or later for using slicing and Indexing as here

$ git clone https://gitlab.com/libeigen/eigen.git

$ mkdir build && cd build
$ cmake .. && sudo make install

• Ceres solver home

$ sudo apt-get install -y cmake libgoogle-glog-dev libatlas-base-dev libsuitesparse-dev

$ make install

• Install CUDA and Graphic Driver:

    $ sudo apt install gcc make
    get the right version of CUDA(with graphic driver) .deb file at https://developer.nvidia.com/cuda-downloads
    follow the installation instructions there!
        # .run file can be used as nvidia graphic driver. But, .deb file is recommended to install tensorRT further.

        # if want to install only graphic driver, get graphic driver install script at https://www.nvidia.com/Download/index.aspx?lang=en-us
        # sudo ./NVIDIA_<graphic_driver_installer>.run --dkms
        # --dkms option is recommended when you also install NVIDIA driver, to register it along with kernel
        # otherwise, NVIDIA graphic driver will be gone after kernel upgrade via $ sudo apt upgrade
    $ sudo reboot

    $ gedit ~/.bashrc
    # type and save
    export PATH=<CUDA_PATH>/bin:$PATH #ex: /usr/local/cuda-11.1
    export LD_LIBRARY_PATH=<CUDA_PATH>/lib64:$LD_LIBRARY_PATH #ex : /usr/local/cuda-11.1
    $ . ~/.bashrc

    # check if installed well
    $ dpkg-query -W | grep cuda

• check CUDA version using nvcc --version

# check installed cuda version
$ nvcc --version
# if nvcc --version does not print out CUDA,
$ gedit ~/.profile
# type below and save
export PATH=<CUDA_PATH>/bin:$PATH #ex: /usr/local/cuda-11.1
export LD_LIBRARY_PATH=<CUDA_PATH>/lib64:$LD_LIBRARY_PATH #ex : /usr/local/cuda-11.1
$ source ~/.profile

● Trouble shooting for NVIDIA driver or CUDA: please see /var/log/cuda-installer.log or /var/log/nvidia-install.log

• Installation failed. See log at /var/log/cuda-installer.log for details => mostly because of X server is being used.
  • turn off X server and install.

# if you are using lightdm
$ sudo service lightdm stop

# or if you are using gdm3
$ sudo service gdm3

# then press Ctrl+Alt+F3 -> login with your ID/password
$ sudo sh cuda_<version>_linux.run

• The kernel module failed to load. Secure boot is enabled on this system, so this is likely because it was not signed by a key that is trusted by the kernel…
  • turn off Secure Boot as below reference
  • If you got this case, you should turn off Secure Boot and then turn off X server (as above) both.

• Download here
• install as below: reference in Korean

$ sudo tar zxf cudnn.tgz
$ sudo cp extracted_cuda/include/* <CUDA_PATH>/include/   #ex /usr/local/cuda-11.1/include/
$ sudo cp -P extracted_cuda/lib64/* <CUDA_PATH>/lib64/   #ex /usr/local/cuda-11.1/lib64/
$ sudo chmod a+r <CUDA_PATH>/lib64/libcudnn*   #ex /usr/local/cuda-11.1/lib64/libcudnn*

• Build OpenCV with CUDA - references: link 1, link 2
  • for Xavier do as below or sh file from jetsonhacks here
  • If want to use C API (e.g. Darknet YOLO) with OpenCV3, then:
    • Patch as here to use other version (3.4.1 is the best)
      • should comment the /usr/local/include/opencv2/highgui/highgui_c.h line 139 as here after install
• -D OPENCV_GENERATE_PKGCONFIG=YES option is also needed for OpenCV 4.X
  • and copy the generated opencv4.pc file to /usr/local/lib/pkgconfig or /usr/lib/aarch64-linux-gnu/pkgconfig for jetson boards
