win10下VSCode配置opencv4.4.0(超详细教程,亲测有效)

VSCode作为一个轻量级的编程软件,无论在界面、内存占用和速度等方面都完胜VS。但用vscode来写opencv代码需要自己编译OpenCV(如果是VS安装opencv则不需要自己编译opencv,因为在opencv的官网上就有编译好的文件),主要用到MinGW-w64和CMake工具。前前后后折腾了好久,终于配好了opencv的环境,写篇博客,一是为了怕自己忘了,又要重新学,二是分享一下自己的经验。主要参考两篇博客:

1.安装MinGW-w64

MinGW-w64下载地址

(参考博客:https://www.cnblogs.com/kensporger/archive/2020/02/19/12320622.html)

配置环境变量

2.安装CMake

CMake下载地址:

https://cmake.org/download/

配置环境变量

记得重启电脑使3个环境变量生效

3.生成MakeFiles

需要去官网下载OpenCV的sources源文件,如果下载太慢,可以找找百度网盘,或者是国内镜像网站

https://www.bzblog.online/wordpress/index.php/2020/03/09/opencvdownload/

注意:是下载opencv对应的source源文件
打开CMake-gui.exe,点击configure,会出现一些问题,主要是会卡在下载ffmpge文件,需要改下host文件,这时只能耐心等待了。再次点击configure,完成后点generate。

Cmake下载文件时一次不成功,那就再来一次

4.编译opencv

CMD到MakeFiles所在文件夹(shift+右键,选择powershell打开),执行minGW32-make命令,或者使用多线程minGW32-make -j 4命令:

编译过程中可能会出现各种各样的错误,不要急,主要是返回第三步,去掉勾选,再次点击configure,generate。

好了,opencv编译成功,最后只剩下在VSCode中配置opencv了(筒子们,离最后的胜利不远了,坚持)

编译完成后记得输入minGW32-make install完成装载,这样才会生成Install文件夹。
