歷史記載
OpenCV4.0貌似GPU加速有點小進步。
Ref: How to use OpenCV’s “dnn” module with NVIDIA GPUs, CUDA, and cuDNN [實操]
Ref: OpenCV ‘dnn’ with NVIDIA GPUs: 1549% faster YOLO, SSD, and Mask R-CNN
Official: https://opencv.org/opencv-4-0/
dnn module was updated with Deep Learning Deployment Toolkit from the OpenVINO™ toolkit R4. See the guide how to build and use OpenCV with DLDT support. dnn module now includes experimental Vulkan backend and supports networks in ONNX format.
一、過去
However, the biggest problem with OpenCV’s dnn module was a lack of NVIDIA GPU/CUDA support
Led by dlib’s Davis King, and implemented by Yashas Samaga, OpenCV 4.2 now supports NVIDIA GPUs for inference using OpenCV’s dnn module, improving inference speed by up to 1549%!
刪除老殘窮版本：
cd ./build sudo make uninstall sudo rm `find /usr/ ! -path "/usr/local/anaconda*" ! -path "/usr/local/opencv*" -name "*opencv*"` -rf
二、現在
- C++版本
You can then run the following cmake command, making sure you set the CUDA_ARCH_BIN variable based on your NVIDIA GPU architecture version, which you found in the previous section:
$ cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D INSTALL_C_EXAMPLES=OFF \ -D OPENCV_ENABLE_NONFREE=ON \ -D WITH_CUDA=ON \ -D WITH_CUDNN=ON \ -D OPENCV_DNN_CUDA=ON \ -D ENABLE_FAST_MATH=1 \ -D CUDA_FAST_MATH=1 \ -D CUDA_ARCH_BIN=7.5 \ -D WITH_CUBLAS=1 \ -D OPENCV_EXTRA_MODULES_PATH=/usr/local/opencv/opencv_contrib/modules \ -D HAVE_opencv_python3=ON \ -D PYTHON_EXECUTABLE=/usr/local/anaconda3/bin/python \ -D BUILD_EXAMPLES=ON ..

Install OpenCV 4 on Ubuntu 18.04 (C++ and Python) [安裝依賴包可以借鑒]
How to install OpenCV 4.2 with CUDA 10.0 in Ubuntu 18.04 [看上去不錯的樣子]
OpenCV使能CUDA加速 [感動的要哭了，更好一些，下面那個更好]
配置成功的話，編譯中能看到在編譯.cu文件。

- 安裝python版本
pip install opencv-python
這么做，不是cuda版本。自己編譯完后執行才可以，如下所示：
$ sudo ldconfig
The final step is to sym-link the OpenCV library into your Python virtual environment.
- 安裝虛擬環境
$ sudo pip install virtualenv virtualenvwrapper # ~./bashrc # virtualenv and virtualenvwrapper export WORKON_HOME=$HOME/.virtualenvs export VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 source /usr/local/bin/virtualenvwrapper.sh $ mkvirtualenv opencv_cuda -p python3 $ workon opencv_cuda
- 配置參數歸總
[小建議]：cmake 的 python for build 會自動找python2，暫時將python2改名，騙過cmake即可。

必備步驟實操
GPU 驅動
一、Cuda 卸載
Ref: Build from source
版本都是對應的。
| tensorflow_gpu-1.14.0 | 2.7, 3.3-3.7 | GCC 4.8 | Bazel 0.24.1 | 7.4 | 10.0 |
| tensorflow_gpu-1.13.1 | 2.7, 3.3-3.7 | GCC 4.8 | Bazel 0.19.2 | 7.4 | 10.0 |
For CUDA 10.1, try:
sudo /usr/local/cuda/bin/cuda-uninstaller
For CUDA 10.0, try:
sudo /usr/local/cuda/bin/uninstall_cuda_10.0.pl
二、Cuda 安裝
-
手動安裝方式
Ubuntu installs its driver firstly and uses nvidia-smi to check the version.
We can see that Cuda 10.1 is required.

Add NVIDIA package repositories.
然后，直接從倉庫下載。

OpenCV Cuda 編譯版本
一、依賴問題
OpenCV編譯沒問題，編譯工程可能會出現該問題。
對‘TIFFReadDirectory@LIBTIFF_4.0’未定義的引用
網上有介紹通過sudo apt-get install libtiff4-dev安裝，但是運行該命令后，提示libtiff4-dev已經被libtiff5-dev替代，只可安裝libtiff5-dev，安裝后並未解決問題。
其原因時安裝的libtiff庫和opencv和PLC中調用的libtiff庫版本與安裝的版本不對應，去libtiff管網上下載 tiff-4.0.4.tar.gz壓縮包安裝即可。
開cuda的一些fps對比數據。
Allow the OpenCV's DNN module to work with GPUs
二、已驗證的安裝
