Installing and Configuring OpenCV for Visual Studio 2022

I apologize for the stuffy voice and heavy breathing in the video.
This tutorial is for the 2022 release of Visual Studio, and release 4.7.0 of OpenCV.
Example code:
In comments. KZbin does not allow angled brackets in the description of videos for some reason.

Thank you! You're the bright light of hope that saves us, beginner programmers, from uncertainties.

[@billakos_san4479]

Thanks so much mate, finally a tutorial that explains everything in depth.

[@noahnetz649]

Example code: **Don't forget to change the path location of the image** #include #include #include #include using namespace cv; int main() { cv::Mat img = cv::imread("C:/Users/Noahj/Desktop/Image.png"); namedWindow("First OpenCV Application", WINDOW_AUTOSIZE); cv::imshow("First OpenCV Application", img); cv::moveWindow("First OpenCV Application", 0, 45); cv::waitKey(0); cv::destroyAllWindows(); return 0; }

For everyone who getting a error like "LNK1104: cannot open file 'opencv_world470d.lib" you probly using different version opencv change your Additional Dependencies value to "opencv_world490.lib, opencv_world490d.lib" if your using 4.90 version

[@screwandwrenchrob4778]

Thank You! You're a life saver, for me I'm running 4.10 and its world4100 if you are having trouble finding it its in x64>v16>lib

GUys help what do I do I nedd OpenCV for x86 visual studio 2022

[@techcooper911]

Change x86 to x64 the option is on the top

[@rexuph7242]

hi sir i get "LNK1104: cannot open file 'opencv_world470d.lib'" error

[@rexuph7242]

Update I Fixed it i changed opencv_world490d.lib and the opencv_world490.lib this will only work if your using openCV 4.9v

[@noahnetz649]

What version of OpenCV are you running? the file opencv_world470d.lib file is for OpenCV 4.7. If you are running a different version of OpenCV, the number in the name of the file will change. For example, for OpenCV 4.9, the file would be opencv_world490d.lib Hope that helps!

same problem, any updates ?

[@SleepyyyStardust]

@@bumbac7440 it works for me now but im not sure how i did it, try this: 1. Make sure you went to Project Properties -> Linker -> Input and added the two lib files to "Additional dependencies", the file names change throughout versions, so opencv_world470d.lib is for version 4.70, and opencv_world4100d.lib is for 4.10.0 2. Make sure you went to the VC++ Directories in the Project Properties and added the two folders you needed to include, eg.. C:/pathtoyouropencvdirectory/build/include and C:/pathtoyouropencvdirectory/build/x64/vc16/lib 3. Try restarting your Visual Studio if that all did not work.... try contacting him or watch the tutorial again but more carefully, hope that helped :)

[@lucasvu1539]

the video is a little outdated but use this example code instead! : #include #include #include #include using namespace cv; int main() { // Replace the path with the actual path to your image cv::Mat img = cv::imread("C:\\Users\\osoao\\OneDrive\\Pictures\\image.png"); if (img.empty()) { std::cerr

[@tbogamer2244]

it is not working image is not being read ive done exactly as your video [ WARN:0@0.022] global loadsave.cpp:248 cv::findDecoder imread_('►n°-1☻ Could not open or find the image

[@MrsLyxing]

that's because you have to put an image by yourself to the path you indicated. So just go to google download an image and your image path on your code should be the same as where your image is. This test code is made to show the image in a new window :)

[@tbogamer2244]

@@MrsLyxing I added the correct path

[@MrsLyxing]

@@tbogamer2244 and it still doesn’t work ? That’s weird, I just tested it and it worked for me

[@tbogamer2244]

@bumbac7440 I couldn't find any solution, and i then started using the STB image library instead of open cv
