3遇到的警告及解决方案 3.1ippicv无法下载
CMake Warning at cmake/OpenCVDownload.cmake:202 (message): IPPICV: Download failed: 6; "Couldn't resolve host name"For details please refer to the download log file:E:/Tools/OpenCV/OpenCV-4.5.5-Build/CMakeDownloadLog.txtCall Stack (most recent call first): 3rdparty/ippicv/ippicv.cmake:37 (ocv_download) cmake/OpenCVFindIPP.cmake:259 (download_ippicv) cmake/OpenCVFindLibsPerf.cmake:12 (include) CMakeLists.txt:732 (include)

【OpenCV|Visual Studio 2022配置OpenCV455+CMake(Win11)】解决方案:参考
  1. 打开E:\Tools\OpenCV\OpenCV-4.5.5-Build文件夹下的CMakeDownloadLog.txt找到
    #do_unpack "ippicv_2020_win_intel64_20191018_general.zip" "879741a7946b814455eee6c6ffde2984" "https://raw.githubusercontent.com/opencv/opencv_3rdparty/a56b6ac6f030c312b2dce17430eef13aed9af274/ippicv/ippicv_2020_win_intel64_20191018_general.zip" "E:/Tools/OpenCV/OpenCV-4.5.5-Build/3rdparty/ippicv"
    #check_md5 "E:/Tools/OpenCV/opencv-4.5.5/.cache/ippicv/879741a7946b814455eee6c6ffde2984-ippicv_2020_win_intel64_20191018_general.zip"
  2. https://raw.githubusercontent.com/opencv/opencv_3rdparty/a56b6ac6f030c312b2dce17430eef13aed9af274/ippicv/ippicv_2020_win_intel64_20191018_general.zip为下载地址,在https://ghproxy.com/的搜索框输入即可下载
  3. 重命名为879741a7946b814455eee6c6ffde2984-ippicv_2020_win_intel64_20191018_general.zip
  4. 将重命名后的文件放入E:\Tools\OpenCV\opencv-4.5.5.cache\ippicv中
3.2ffmpeg无法下载
CMake Warning at cmake/OpenCVDownload.cmake:202 (message): FFMPEG: Download failed: 6; "Couldn't resolve host name"For details please refer to the download log file:E:/Tools/OpenCV/OpenCV-4.5.5-Build/CMakeDownloadLog.txtCall Stack (most recent call first): 3rdparty/ffmpeg/ffmpeg.cmake:20 (ocv_download) modules/videoio/cmake/detect_ffmpeg.cmake:14 (download_win_ffmpeg) modules/videoio/cmake/init.cmake:7 (include) modules/videoio/cmake/init.cmake:11 (add_backend) cmake/OpenCVModule.cmake:298 (include) cmake/OpenCVModule.cmake:361 (_add_modules_1) cmake/OpenCVModule.cmake:385 (ocv_glob_modules) CMakeLists.txt:927 (ocv_register_modules)

解决方案:
  1. opencv_videoio_ffmpeg.dll:https://raw.githubusercontent.com/opencv/opencv_3rdparty/4d348507d156ec797a88a887cfa7f9129a35afac/ffmpeg/opencv_videoio_ffmpeg.dll
    重命名为eece4ec8304188117ffc7d5dfd0fc0ae-opencv_videoio_ffmpeg.dll
  2. opencv_videoio_ffmpeg_64.dll:https://raw.githubusercontent.com/opencv/opencv_3rdparty/4d348507d156ec797a88a887cfa7f9129a35afac/ffmpeg/opencv_videoio_ffmpeg_64.dll
    重命名为20deefbfe023c8b8d11a52e5a6527c6a-opencv_videoio_ffmpeg_64.dll
  3. ffmpeg_version.cmake:https://raw.githubusercontent.com/opencv/opencv_3rdparty/4d348507d156ec797a88a887cfa7f9129a35afac/ffmpeg/ffmpeg_version.cmake
    右键另存为8862c87496e2e8c375965e1277dee1c7-ffmpeg_version.cmake
  4. 将这三个文件放入E:\Tools\OpenCV\opencv-4.5.5.cache\ffmpeg中
3.3wechat_qrcode无法下载 与1.3.1和1.3.2操作类似。
全部完成后点Generate,等待完成。
4Visual Studio编译 (1)生成后点Open Project,选择Debug x64或Release x64。
(2)找到ALL_BUILD,右键生成,等待完成。

(4)E:\Tools\OpenCV\OpenCV-4.5.5-Build\install 该路径为环境配置所需。
5环境配置 1.添加系统环境变量E:\Tools\OpenCV\OpenCV-4.5.5-Build\install\x64\vc17\bin
2.新建项目属性表(这里配置的是Release版)

3.VC++目录–包含目录添加路径:
E:\Tools\OpenCV\OpenCV-4.5.5-Build\install\include
E:\Tools\OpenCV\OpenCV-4.5.5-Build\install\include\opencv2

5.链接器–输入–附加依赖项添加:
opencv_world455.lib(Release版)
opencv_world455d.lib(Debug版)

6测试
#include #include //日志头文件 #include using namespace cv; using namespace std; int main() { //utils::logging::setLogLevel(utils::logging::LOG_LEVEL_SILENT); //不输出日志 //utils::logging::setLogLevel(utils::logging::LOG_LEVEL_ERROR); //只输出错误日志 Mat src = https://www.it610.com/article/imread("C:/Users/12421/Desktop/Lena.jpg"); if (src.empty()) { cout << "please cheak image path" << endl; return -1; } Mat src_x, src_y, src_xy; flip(src, src_x, 0); //沿x轴对称 flip(src, src_y, 1); //沿y轴对称 flip(src, src_xy, -1); //沿x轴对称,沿y轴对称 imshow("src", src); imshow("src_x", src_x); imshow("src_y", src_y); imshow("src_xy", src_xy); waitKey(0); return 0; }

结果:
7其他 1.帮助文档下载:https://docs.opencv.org/
2.OpenCV455Debug版本运行时CMD框会显示很多日志,关闭的方法:参考
添加头文件#include
main()函数里添加语句cv::utils::logging::setLogLevel(utils::logging::LOG_LEVEL_SILENT);
