在WSL-Ubuntu20.04下安装OpenCV-3过程以及遇到的问题和相应的解决办法 - LesPlumes - 博客园
我是wsl2-ubuntu18.04安装ros后已有opencv3.2.0现在要再装opencv3.3.1
一.下载和安装依赖包
1、首先更新 apt-get在安装前最好先更新一下系统不然有可能会安装失败。在终端输入
sudo apt-get update
sudo apt-get upgrade2、接着安装官方给的opencv依赖包在终端输入
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev 下面的步骤我做了 错误E: 无法定位软件包 libjasper-dev sudo add-apt-repository deb http://security.ubuntu.com/ubuntu xenial-security main sudo apt update sudo apt install libjasper1 libjasper-dev 二.下载源文件
下载opencv-3.3.1以及opencv_contrib-3.3.1。
opencv-3.3.1可以到官网或者github上去下载源文件官网版本选择在下方翻页github上通过tag选择。
wget -q https://github.com/opencv/opencv/archive/3.3.1.zip解压源文件并进入
unzip opencv-3.3.1.zip
cd opencv-3.3.1/ opencv_contrib下载连接GitHub - opencv/opencv_contrib: Repository for OpenCVs extra modules 将opencv_contrib-3.3.1文件夹放入opencv-3.3.1文件夹内(我这里的opencv_contrib-3.3.1改名为opencv_contrib)。 三.安装
1.编译前的准备工作
①在进行cmake之前将“Opencv3缺失文件”这个文件夹中的所有.i文件都复制到 opencv3_contrib\modules\xfeatures2d\src\这个目录下。 (百度网盘https://pan.baidu.com/s/15QlHwu5ur2vc6ncyVS4e_Q 提取码sysu)
②在进行make之前将以下路径 opencv-3.3.1\opencv_contrib\modules\xfeatures2d\include\opencv2\ 的xfeatures2d文件夹和xfeatures2d.hpp都copy到 opencv-3.3.1\build\opencv2\路径下。 opencv_contrib下载连接https://github.com/opencv/opencv_contrib
sudo mv opencv_contrib/modules/xfeatures2d/include/opencv2/xfeatures2d build/opencv2
sudo mv opencv_contrib/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp build/opencv2 ③在进行make之前下载nvida_sdk链接https://pan.baidu.com/s/1IykEbf7SZgf2IE0T52_bqA 提取码sysu
然后把下载下来的Video_Codec_Interface_12.1.14\Video_Codec_Interface_12.1.14\Interface\目录下的三个文件
都复制到opencv-3.3.1/modules/cudacodec/src/下
再依次打开以下文件 precomp.hpp、video_decoder.hpp、cuvid_video_source.hpp、 frame_queue.hpp、video_parser.hpp 将 #if CUDA_VERSION 9000 修改为 #if CUDA_VERSION 9000 CUDA_VERSION 10000
sudo mv /home/leaf1804/Video_Codec_Interface_12.1.14/Interface/cuviddec.h /home/leaf1804/opencv-3.3.1/modules/cudacodec/srcsudo mv /home/leaf1804/Video_Codec_Interface_12.1.14/Interface/nvcuvid.h /home/leaf1804/opencv-3.3.1/modules/cudacodec/srcsudo mv /home/leaf1804/Video_Codec_Interface_12.1.14/Interface/nvEncodeAPI.h /home/leaf1804/opencv-3.3.1/modules/cudacodec/src ④在进行make之前打开opencv-3.3.1\modules\videoio\src\ cap_ffmpeg_impl.hpp添加以下宏定义 #define AV_CODEC_FLAG_GLOBAL_HEADER (1 22) #define CODEC_FLAG_GLOBAL_HEADER AV_CODEC_FLAG_GLOBAL_HEADER #define AVFMT_RAWPICTURE 0x0020 2.编译opencv
cd opencv-3.3.1
mkdir build cd build
sudo cmake -D CMAKE_BUILD_TYPERelease -D CMAKE_INSTALL_PREFIX/home/leaf1804/software/opencv3.3.1 -D CUDA_NVCC_FLAGS-D_FORCE_INLINES -D BUILD_opencv_cudacodecOFF -D OPENCV_EXTRA_MODULES_PATH../opencv_contrib/modules ..sudo make -j6
sudo make install
报错1
运行sudo make -j6的时候报错 [ 46%] Building NVCC (Device) object modules/cudabgsegm/CMakeFiles/cuda_compile.dir/src/cuda/cuda_compile_generated_mog2.cu.o /home/leaf1804/opencv-3.3.1/modules/core/include/opencv2/core/cuda/vec_math.hpp(203): error: calling a constexpr __host__ function(abs) from a __device__ function(abs) is not allowed.

成功了 然后运行sudo make install 成功 报错后可以清理并重新配置
在尝试修复之前可以确保清理 build 目录以避免遗留问题
cd /home/leaf/opencv-3.3.1/build
rm -rf *我还删除过一次opencv-3.3.1和opencv_contrib文件夹从头开始再来过一次 四.切换不同版本opencv
打开bashrc文件(~/.bashrc)主目录下 gedit ~/.bashrc 并加入
# # opencv-3.3.1
# export PKG_CONFIG_PATH~/software/opencv3.3.1/lib/pkgconfig
# export LD_LIBRARY_PATH~/software/opencv3.3.1/lib#OpenCV 3.2.0
export PKG_CONFIG_PATH/usr/local/lib/pkgconfig
export LD_LIBRARY_PATH/usr/local/lib 用那个取消注释另一个可以使用 pkg-config --modversion opencv 进行验证。
source ~/.bashrc
pkg-config --modversion opencv# 查看详细的路径
pkg-config --cflags --libs opencv 使用多版本opencv
在写CmakeList.txt如果只有一个版本的opencv,我们一般直接使用
FIND_PACKAGE(OpenCV REQUIRED)
如果现在要使用的是默认安装的opencv3.2.0,则使用使用上面的指令就足够了。
如果现在要使用的是我们自己指定路径的opencv-3.3.1则在上面指令前面加上如下指令
set(OpenCV_DIR /home/wh/opencv4/lib/cmake/opencv4)引号里面的地址是OpencvConfig.cmake地址 OpenCVConfig.cmake 是 OpenCV 库的 配置文件。它是用来告诉项目如何使用 OpenCV 库的。它包含了 OpenCV 库的路径信息、版本信息和链接信息等。当项目使用 find_package(OpenCV) 命令时CMake 就会去寻找这个文件并读取其中的信息最终使项目可以使用 OpenCV 库。 比如我的就要在原来的cmakelist.txt里面加上一句
set(OpenCV_DIR /home/leaf1804/software/opencv3.3.1/share/OpenCV)因为我的OpencvConfig.cmake地址是这里
