opencv配置安装

1、安装方式

https://blog.csdn.net/qq_45022687/article/details/120241068

根据这个网址的配置进行安装

2、解编译

1. mutex/thread等

   似乎因为mingw的问题,#include 等直接引入线程无法直接引用，这导致了原有代码中直接使用mutex/thread的部分需要修改

2. opengl未成功链入

   • 问题描述

     

   • 解决过程

     • 尝试在出问题的文件中，添加头文件#include <windows.h>，解决

       参考：https://blog.csdn.net/zhongjling/article/details/7535585

3. 重复定义

   • 问题描述

     

   • 解决过程

     在同一个文件中定义了同一个宏定义，在对应的定义和使用的地方做相应的修改

     

     

4. 返回类型不完全

   • 问题描述

     

   • 解决过程

     把有问题的函数全部注释了

5. ERROR: Unable to start debugging. Unexpected GDB output from command “-exec-run”. During startup program exited with code 0xc0000135.

     调整mingw/bin在环境变量中的相对位置

4、安装编译mediapipe

1）python下载mediapipe

1. pip install mediapipe

2. 下载mediapipe库

   • 地址：https://pypi.org/project/mediapipe/#files

   • 命令：pip install --user mediapipe-0.8.9.1-cp310-cp310-win_amd64.whl

     

     安装失败了……

     

   • opencv-contrib-python

     • opencv-contrib-python

     • 下载资源包

       • 地址：https://pypi.tuna.tsinghua.edu.cn/packages/b2/b8/d5c14d6a0b1d898f7fe273de9b41f84dd94a5cc4c816a32da300fc70a1d5/opencv_contrib_python-4.7.0.68-cp37-abi3-win_amd64.whl#sha256=7a75f1775790106e54bcfb101c0e00e1f801a57d9baebc82d0b6758fc83a4ca0

       • pip install --user opencv_contrib_python-4.7.0.68-cp37-abi3-win_amd64.whl

       • 安装成功

         

   • 再次安装mediapipe

2) c++安装

1. MSYS2安装

   • 下载地址：https://www.msys2.org

   • 安装

     

   • 配置环境变量

     地址：D:\Setting\msys64\usr\bin

     

   • 升级msys2包数据库

     

     pacman -Syu

   • 下载unzip

     MSYS2没有内置unzip，需要手动安装

     pacman -S git patch unzip

     

2. python配置

   装过了

3. 安装VS2019和WinSDK

   VS官网：https://aka.ms/vs/17/release/vs_BuildTools.exe

   

4. 配置Bazel

   • 地址：https://github.com/bazelbuild/bazel/releases/download/5.2.0/bazel-5.2.0-windows-x86_64.exe

   • 移动到目的位置，并修改为bazel.exe

     

   • 修改环境变量

     set BAZEL_VS=D:\Software\Microsoft Visual Studio\2022\Community
     set BAZEL_VC=D:\Software\Microsoft Visual Studio\2022\Community\VC
     set BAZEL_VC_FULL_VERSION=14.34.31938.0
     set BAZEL_WINSDK_FULL_VERSION=10.1.22000.832
     

     

     

   • 设置Bazel变量

5. mediapipe仓库克隆及bazel的编译文件WORKSPACE的修改

   • git clone https://github.com/google/mediapipe.git

   • 设置opencv地址-WORKSPACE

     

   • 设置open_windows.BUILD

     

6. 编译

   切换打破media仓库目录，运行：bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 --action_env PYTHON_BIN_PATH="D:\\Setting\\Python\\python.exe" mediapipe/examples/desktop/hello_world

   

7. 执行

   set GLOG_logtostderr=1

   bazel-bin\mediapipe\examples\desktop\hello_world\hello_world.exe
