I am trying to generate Arcuo Marker and Detect the marker in Visual Studio 2019 vc16, I am using OpenCV version 4.7 and i am using a already written code of generating Arcuo marker, in the code they have aruco.hpp header file but in the new version they do not have that, it is moved in the objectdetect folder. I am just confused that how can I use or call Arcuo, because I am not sure what was in the previous version. Any help will be appreciated.
I tried to use older version, in those I could not see aruco.hpp as well. I am confused because how it is not there while everyone is using it? what am I Missing??
You need to build OpenCV with its contribs.
There's also an option for that in Conan if you happen to use it.
Then aruco.hpp will be available here.

I am trying to do the following: getting to work
CUDA 9.1 with
openCV 3.4.2 and
Visual Studio Enterprise 2015 (v 14.0 Update 3) on
Windows 7 Enterprise x64 SP 1 using
CMake 3.12.0
and also searching for others with the same problem - no success there.
I have worked through this tutorial on getting the software to work together. I do not intend to use Intel MKL and TBB.
I have succeeded in
installing CUDA
generating the Makefiles for openCV with CMake, and having the CUDA libraries included without any mistakes (barring the download of optional stuff, as the PC I am working on is to stay off the internet)
generating the .sln solution file for building openCV in Visual Studio
The problem is in the next step - building openCV. The compiler claims that "opencv2/opencv_modules.hpp" cannot be opened by gpu_mat_cu when it tries to build opencv_world. The thing is that the include path works according to Visual Studio - it detects the right file in the gpu_mat.cu. The project (opencv_world) has the right directory in its include paths as static path.
I am new to Visual Studio (I worked in Linux with QT, CUDA and openCV before), so I am not too sure I am not missing some kind of settings I should change.
The opencv_world.hpp only consists of #define instructions. I have tried deleting the include of opencv_world.hpp and instead just defining the parameter in gpu_mat.cu itself, but if I do, the next include (that, again, VS finds the path to without problems) is not resolved.
I guess there is something obvious I am missing, but I don't seem to be able to resolve this issue, so thanks in advance for your help.

P.S.: The files CMake wanted to download for openCV and failed at (obviously; no internet connection) are: opencv_ffmpeg.dll, opencv_ffmped64.dll, ffmpeg_version.cmake, ippicv_2017u3_win_intel64_general_20180518.zip, res10_300x300_ssd_iter_140000_fp16.caffemodel and opencv_face_detector_uint8.pb
I'd add the CMakeCache.txt file in a spoiler tag, but it has too many characters. If you think it would help, let me know and I'll upload it somewhere.
I got the solution, just in case someone stumbles over the same problem: it's the most simple thing that everybody knows until they don't - my include path contained a white space that apparently somewhere was treated as a String divider for whatever interprets that path.
This is my first post to this site. I'm hoping that someone can help me out.
I am doing some work with the Microsoft Kinect for Windows and I am trying to set up visual studio to use GLUT. The code builds successfully, but I keep getting the following error message when I try to run the program in Visual Studio:
The program can't start because freeglut.dll is missing from your
computer. Try reinstalling the program to fix this problem.
I have installed the Microsoft SDK and Developer Toolkit for the Kinect and I am using Visual Sutdio 2010. I followed the instructions on this tutorial, Kinect SDK C++, in order to set everything up, including downloading the freeglut 2.8.1 MSVC Package and copying the appropriate files into various folders as per the tutorial instructions. I have tried renaming freeglut.dll to glut32.dll as the tutorial suggests and leaving it unchanged.
The code I'm using is the sample code from the second page of the tutorial. I've also tried the source code provided in this tutorial: Programming KINECT in C++ and OpenGL — Color Stream Rendering. Both build fine, but yield the same error when run.
I tried deleting the freeGLUT files and replacing them, rearranging their folder structure in the SDK folders (and changing the corresponding filepaths in my project properties) as well as following the solution presented in this post: compiled program cannot find freeglut.dll. So far nothing is working and that last solution actually caused the both codes I'm using to fail building with error MSB3073.
I would appreciate any insight you might have into this issue.
Thank you!
I have written an openCV code and my code has following statement:
cv::imshow("Matches", matchesImg);
cv::waitKey(0);
When I run the code either in Debug or Release I am not able to see window which shows me the output.
And this is happening for every project I create.
Not able to figure out the reason, Can someone please guide me on this?
I am coding on Windows 7 and Visual studio 2010, with opencv version of 2.4.6
As I mentioned in the comments, you have to create a window first, using namedWindow with the same window name as in imshow
See this tutorial for details.
EDIT
This strongly suggest that you have to create the window beforehand.
Some may argue that it didn't work this way for previous versions of OpenCV. Then, let's say this solution apply at least to OpenCV 2.4.6, which is the version of concern here (and it solved the problem).
I am starting up with OpenCV (using C++) and was playing around with the "Feature matching with FLANN" tutorial from here:
http://opencv.itseez.com/doc/tutorials/features2d/feature_flann_matcher/feature_flann_matcher.html
I did not modify anything, just tried running it as it is. Unfortunately, when running it, I am getting this error when the program tries to detect the keypoints (on the line detector.detect(img_1, keypoints_1)) :
I had no problems with running other OpenCV tutorials out of the box...did anyone experience similar problems?
My system: Visual Express 2010 and OpenCV 2.3, under Windows 7 64-bit. Could this be a bug of v2.3, or some issues related to the 64-bitness of my system?
It sure helps to know more about C++ than a worm :) I realized I had linked against the release version of the feature2d lib. As always, solved automatically by virtue of the "power of posting"...
I have same mistake with your‘s，because you have use different Version of lib file.
If you use debug,you must use lib ended by 'd'.
I am trying to run an application that can train and fit active appearance models for my research. The application is the AAM-library (and can be found here http://code.google.com/p/aam-library/)
I am using Visual Studio 2005 in Windows XP 64-bit. I am using openCV 1.0 because the developer of the application writes that he's not sure that the app will work with openCV 2.0.
I have compiled openCV and the AAM-library. When I try to run the AAM-library I get the error message:
Unsupported format or combination of formats (The image/matrix format is not supported by the function) in function cvBoundingRect, C:\User\VP\opencv\cv\src\cvshapedescr.cpp(1171)
The developer writes in the readme that:
In order to make it work, you must modify a bug in OpenCV and rebuild it:
cvBoundingRect() doesn't work fine.
opencv/cv/src/cvshapedescr.cpp around line 1161
replace CV_32SC1 to CV_32SC2 and CV_32FC1 to CV_32FC2.
I have done this. I have also rebuilt both openCV and the AAM-library. But I keep on getting the same error. I'm new to Visual Studio and openCV (and C++!) so may be missing something obvious. Any suggestions?
I had trouble running OpenCV 1.0 on 64bit systems when working with our image processing software for a robot project. We used the legacy version because of some code files we had. We eventually had to move up to 2.2. If you have already tried 2.0, is there anyway to remove that portion of the library?
