安裝Eigen3

sudo apt-get install libeigen3-dev
#拷貝
sudo cp -r /usr/local/include/eigen3/Eigen /usr/local/include

在自己要安裝opencv的位置下載opencv3.4.1 github source: 可以到gitub下載:(可能比較慢)

wget https://github.com/opencv/opencv/archive/3.4.1.zip
wget https://github.com/opencv/opencv_contrib/archive/3.4.1.zip

sudo apt-get install aria2
aria2c -c -s10 -k1M -x16 --enable-rpc=false -o "opencv-3.4.1.zip" --header "User-Agent: netdisk;5.3.4.5;PC;PC-Windows;5.1.2600;WindowsBaiduYunGuanJia" --header "Referer: https://pan.baidu.com/disk/home" --header "Cookie: BDUSS=paa3hGV3dYbnpoQlRDOG5jYnlqSEVlU3lDbXVNV2dybFF6ZTEzbzZJZ0JlMmxiQVFBQUFBJCQAAAAAAAAAAAEAAACyHgg5aGhnw~vR78zsz8IAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHuQVsB7kFbS3; pcsett=1538270082-2dc1426f5364346f2129902dc3319353" "https://pcs.baidu.com/rest/2.0/pcs/file?method=download&app_id=250528&path=%2FOpencv%2Fopencv-3.4.1.zip"
 

下載opencv contrib:

aria2c -c -s10 -k1M -x16 --enable-rpc=false -o "opencv_contrib-3.4.1.zip" --header "User-Agent: netdisk;5.3.4.5;PC;PC-Windows;5.1.2600;WindowsBaiduYunGuanJia" --header "Referer: https://pan.baidu.com/disk/home" --header "Cookie: BDUSS=paa3hGV3dYbnpoQlRDOG5jYnlqSEVlU3lDbXVNV2dybFF6ZTEzbzZJZ0JlMmxiQVFBQUFBJCQAAAAAAAAAAAEAAACyHgg5aGhnw~vR78zsz8IAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHuQVsB7kFbS3; pcsett=1538270082-2dc1426f5364346f2129902dc3319353" "https://pcs.baidu.com/rest/2.0/pcs/file?method=download&app_id=250528&path=%2FOpencv%2Fopencv_contrib-3.4.1.zip"
 

下載cmake的時候需要下載的檔案:(這一步不是必須,可能會用到,博主沒有用到這個):

aria2c -c -s10 -k1M -x16 --enable-rpc=false -o "cache.zip" --header "User-Agent: netdisk;5.3.4.5;PC;PC-Windows;5.1.2600;WindowsBaiduYunGuanJia" --header "Referer: https://pan.baidu.com/disk/home" --header "Cookie: BDUSS=paa3hGV3dYbnpoQlRDOG5jYnlqSEVlU3lDbXVNV2dybFF6ZTEzbzZJZ0JlMmxiQVFBQUFBJCQAAAAAAAAAAAEAAACyHgg5aGhnw~vR78zsz8IAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHuQVsB7kFbS3; pcsett=1538273029-13c03449b730a73ee159ac325a27deb6" "https://pcs.baidu.com/rest/2.0/pcs/file?method=download&app_id=250528&path=%2FOpencv%2Fopencv3.4.1%E7%BC%96%E8%AF%91%E6%97%B6%E9%9C%80%E8%A6%81%E4%B8%8B%E8%BD%BD%E7%9A%84%E6%96%87%E4%BB%B6%2Fcache.zip"

按道理上面的下載好,分別解壓,然後如下操作就可以編譯通過了

unzip opencv-3.4.1.zip
unzip opencv_contrib-3.4.1.zip

將opencv_contrib-3.4.1 拷貝到opencv-3.4.1資料夾下

cd opencv-3.4.1
mv ../opencv_contrib-3.4.1/   ./opencv-3.4.1/
mkdir build
mkdir install
cd build
#cmake的時候選項對應自己的情況作相應的修改,一下 -D CMAKE_INSTALL_PREFIX= 後面的地址改為你要安裝的地址

修改: #include<unsupported/Eigen/MatrixFunctions> 為: #(此處為你最上面安裝eigen的時候的路徑,可以在computer下搜尋MatrixFunctions確定路徑位置) #include</usr/include/eigen3/unsupported/Eigen/MatrixFunctions>

設定opencv環境變數:

#設定環境變數,這裡依據自己上面設定的安裝路徑來設定
