解除安裝opencv4tegra；重新安裝opencv3.4.0

1、檢視已安裝的opencv版本号

pkg-config --modversion opencv
           

2、解除安裝opencv4tegra

sudo apt-get purge libopencv*
sudo apt autoremove
sudo apt-get update
           

3、下載下傳opencv3.4.0+contrib，安裝依賴包

1. 下載下傳opencv和opencv_contrib

   opencv：https://opencv.org/releases.html

   opencv_contrib：https://github.com/opencv/opencv_contrib/tree/3.4.0

2. 安裝必要的庫

   sudo apt-get install build-essential sudo apt-get install cmake git g++

3. 安裝依賴包

   sudo apt-get install libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev sudo apt-get install checkinstall yasm libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libfaac-dev libmp3lame-dev libtheora-dev sudo apt-get install libopencore-amrnb-dev libopencore-amrwb-dev libavresample-dev x264 v4l-utils

4. 處理圖像所需的包

   sudo apt-get install libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev 
   
              

5. 處理視訊所需包

   sudo apt-get install libxvidcore-dev libx264-dev ffmpeg
              

6. opencv功能優化

   sudo apt-get install libatlas-base-dev gfortran 
              

7. 其他依賴包

   sudo apt-get install libopencv-dev  libqt4-dev qt4-qmake libqglviewer-dev libsuitesparse-dev libcxsparse3.1.4 libcholmod3.0.6 
   sudo apt-get install python-dev python-numpy
              

8. 可選依賴

   sudo apt-get install libprotobuf-dev protobuf-compiler
   sudo apt-get install libgoogle-glog-dev libgflags-dev
   sudo apt-get install libgphoto2-dev libeigen3-dev libhdf5-dev doxygen
              

4、編譯和安裝

解壓opencv3.4.0，再将opencv_contrib-3.4.0解壓到opencv3.4.0目錄中；

進入opencv3.4.0目錄，建立子目錄build：

cd ~/opencv-3.4.0/
mkdir build
           

在build下建立my_cmake.sh：

cd build
touch my_cmake.sh
vim my_cmake.sh
           

檔案内容（cuda8.0）：

#!/bin/bash
cmake \
    -D CMAKE_BUILD_TYPE=Release \
    -D CMAKE_INSTALL_PREFIX=/usr \
    -D BUILD_PNG=OFF \
    -D BUILD_TIFF=OFF \
    -D BUILD_TBB=OFF \
    -D BUILD_JPEG=OFF \
    -D BUILD_JASPER=OFF \
    -D BUILD_ZLIB=OFF \
    -D BUILD_EXAMPLES=ON \
    -D BUILD_opencv_java=OFF \
    -D BUILD_opencv_python2=ON \
    -D BUILD_opencv_python3=ON\
    -D ENABLE_PRECOMPILED_HEADERS=OFF \
    -D WITH_OPENCL=OFF \
    -D WITH_OPENMP=OFF \
    -D WITH_FFMPEG=ON \
    -D WITH_GSTREAMER=ON \
    -D WITH_GSTREAMER_0_10=OFF \
    -D WITH_CUDA=ON \
    -D WITH_GTK=ON \
    -D WITH_VTK=OFF \
    -D WITH_TBB=ON \
    -D WITH_1394=OFF \
    -D WITH_OPENEXR=OFF \
    -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-8.0 \
    -D CUDA_ARCH_BIN=6.2 \
    -D CUDA_ARCH_PTX="" \
    -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-3.4.0/modules/ \
    ../
           

修改腳本權限：

chmod u+x my_cmake.sh
           

執行腳本：

./my_cmake.sh
           

等待。。。

最後執行編譯安裝

sudo make
sudo make install
